This allows the polluters a smoke screen to hide behind and geiger counter businesses to pop up everywhere. (START YOUR AMZN SHOPPING HERE). These particles are emitted at random intervals, and a large number of particles produced in a short span of time sound … I'm no physicist, but basically here's how it works: There is a large (400+ V) … What type of inhalation exposure did they receive? So basically – its from one extreme to the next. What gives with the big differences between the RADNETWORK website and the NETC website??? Values on our radiation monitors are displayed in both mrem/hr and µSv/h. Thank you for your advice. Do you understand this website? Days compared with the average annual human exposure (U.S.)207 (at 100 CPM)42 (at 500 CPM)14 (at 1,500 CPM)2 (at 10,000 CPM), Days to receive chronic dose for increase cancer risk of 1 in a 1,000432 (at 100 CPM)86 (at 500 CPM)28 (at 1,500 CPM)4 (at 10,000 CPM), Days for earliest onset of radiation sickness25,937 (at 100 CPM)5,187 (at 500 CPM)1,729 (at 1,500 CPM)259 (at 10,000 CPM). Background correlates to expected in South West UK here of around 0.05 to 0.09 uSv/hr. 2.) Thats why its important to know your NORMAL background levels in your area, for your geiger. TGR CPM Annualized City, State Date Read 2019 TGR CPM Why is this so much higher than the alert level you discuss which is 100 CPM? 7/24 33,561,626 Speaking as a wife, I have always totally understood that high levels are NOT a good/safe thing. $99 – rating average on Amazon 4.2 stars (100 reviews) … old) I find I have 3 types of cancer. It was not a CPM measurement, MR/hr I think. 28 (at 1,500 CPM) Reactors are spewing MORE THAN 200 isotopes! To report the ambient radiation levels we can use international units: Gray per hour (Gy/h) Sievert per hour (Sv/h) You didn’t post what measurement scale CPM, mR/h or uSv/h. Don’t sleep with your uranium glass next to you in bed and don’t carry it 24/7 with you and you have nothing to worry about. we had found an expert locally, and at the time it was not unduly expensive (considering the cost of a house/ one’s health) to pay. I understand that the scale and cpm readings you have laid out here are for air born, but do they also work for food. Radiation Units of Measurement. First, we must understand a few radiation facts and numbers regarding dosage. Time (limit exposure time)2. Average annual human exposure to radiation (U.S.)600 milliRem (mRem)6 milliSievert (mSv), Radiation dose for increase cancer risk of 1 in a 1,0001,250 milliRem (mRem)12.5 milliSievert (mSv), Earliest onset of radiation sickness75,000 milliRem (mRem)750 milliSievert (mSv), Onset of radiation poisoning300,000 milliRem (mRem)3,000 milliSievert (mSv), Expected 50% death from radiation400,000 milliRem (mRem)4,000 milliSievert (mSv). No you were not in danger, even at 2,490 CPM that’s only about 20mR an hour, so a total of 40 for the trip. so, having tried to explain all that, It’s possible for one device to have a reading of 150 CPM while another device only reads 50 CPM. 25,937 (at 100 CPM) new solar system on existing commercial roof-top. I believe that we need to talk about our daily survival. Therefore, annual dosage from the radioactive ore equals 200 mR (100 mR/hr x 2 hours per year). In standard operation, the unit makes a quiet beep as a Geiger counter, with a small unlit LCD showing microSv/hour. Should I be concerned for my future health? What we also know OS there are still Hiroshima survivors living today. Experiments with the Geiger counter Is this a safe level? we had someone come and test it, it was ok. but, we absolutely agreed that if levels were high, we would not purchase. total system si. I just bought an inspector Exp and am going around the house checking things out. It is also about distance – distance is your friend. Terms Of Use Here are some basic numbers to use as a guide (μSv means microSieverts): 40 μSv – The radiation you receive by taking a flight from New York to L.A. 800 μSv – Total radiation dose at Three-Mile Island for the duration of the accident. Others are not. 2017 and no one yet knows whether this has occurred. So the background radiation level in my office is varying roughly between 0.05-0.10 uSv/hr, which is a normal, safe level of background radiation (see Radiation Units below). I (at this point) don’t know what “high” levels are, but if the wife’s pottery is high, chuck it. a nuclear bomb blast gives-off just over 20 short-lived isotopes. b) I seem to recall, that the expert we hired, stated that specific in home levels will / can vary, depending on air flow. 56 of them in the #3 pool went up! Our tests are showing 30 to 50% above background. So what do we do? Back round averaging about 36 cpm. 1 rad = 0.01 gray (Gy) 1 gray (Gy) = 100 rad. I cannot imagine anything which I would not chuck, given this. That depends on how long you are exposed at any given level. A small ditch (10 inches deep) next to my house – 22,000 CPM. I have a vintage 1958 wristwatch and the lume radiates at a high level compared to others I own. Not only counting Chernobyl and Fukushima all NPP leak from what that say. Keep in mind that Geiger counters indicate the creation of an ion pair. Older than that uptake is limited because our body’s slow down. Most Geiger counters also have an audio readout that sounds one "click" for each particle count. There were MOX rods there.. but also full rods of Plutonium… BREEDER RODS !!! The common shared pool building has BURNED 5 times! However, you should verify the following government data - research the NIH (. 87,824,984 Portland, ME. I am now sitting here writing this note and see it spiked up to 65. For this, the purchase of a radon detector with an activated carbon filter. might not. The experts have told me that “things are fine, just fine.”, Why don’t I believe them? Does anyone know? The Cs137 calibration factor listed above (120 CPM) was converted to obtain the proper factored results listed below (0.83x). 1,200 CPM on the meter (for Cs137) is about 1 mR/hr (milliRad per hour).120 CPM on the meter (for Cs137) is about 1 uSv/hr (microSievert per hour). Total dose per year, if exceeded increases your chances of cancer. I don’t know what detector they are using to get that reading, and there’s little way to know exactly what kind of radiation it is. The vet assured me their Geiger counter is calibrated at some hospital and her level was safe to go home. Depending on the type of Geiger counter used and the elevation, the average natural background radiation level ranges between five and 60 counts per minute or more. Assume close proximity to the countertop of 3 hours per day, or 1,095 hours per year. A multiplication factor (radiation factor) is used that represents the ‘effective’ biological damage of a given type of radiation. Thanks to the admin and all contributors here for running some good data. Didn’t know what to do. NNormal background levels are very low; 3x very low levels are still very low levels. I’m interested in further understanding the level of MOX plutonium headed here and how to logically respond to it. Ecotest has been successful in maintaining its quality image throughout the time. 120 CPM on the meter (for Cs137) is about 1 uSv/hr (microSievert per hour) or 1000 nanoSieverts/hour. To determine the energy levels of the particles, use a proportional counter. If you ever fly older 747’s, watch out for the DU weight’n’balance in the tail, OK? Additionally, "acceptable" levels of radiation exposure are somewhat subjective, so we encourage you to make your own conclusions as to the maximum levels of radiation exposure which would be acceptable to you: The US Government recommends that you limit your dosage or exposure of radioactivity to the following: *estimated annual exposure to background radiation. Therefore, annual dosage from high altitude flights equals 312 mR (.3 mR/hr x 1,040 hours per year). Geiger counters can not accurately measure the presence of radon gas in a house. Rad and Gray are ‘absorbed dose’ units. Can we use the same scale you are using to determine what our results are telling us? This type of detector is common, but there are other similar products. Fish from Japan, Hawaii, Washington state, Santa Barbara, Alaska, the Atlantic and North Carolina. Therefore, annual dosage from the granite equals 55 mR (.05 mR/hr x 1,095 hours per year). The following data is from an industry source believed to be reliable. (please realize, I am seriously paraphrasing, due to lack of specifics of memory…grin). the first 2 weeks of Fukushima put more than 12 TONS of Plutonium into the air… and the out-gassing that’s been going on since.. only ADDS to the total! I’ve seen several YouTube videos where air filters were measured and the readings were very high. Our salvage ship spent 30 continues days in Bikini lagoon salvaging material off the bottom plus hosing down other equipment. Kale and tomatoes grown in various areas in southern and Central California. Every thing was secret and couldn’t be talked about under threat of court marshal and jail. Days to receive chronic dose for increase cancer risk of 1 in a 1,000 Thanks for your advice in advance. Typo, I was thinking it was the Jan. 4th when it was Jan. 3rd. Higher freq gets there faster. Radiation @ Fukushima Dai-ichi MP-1, Fukushima, JP is 2400 nSv/hr; Radiation in downtown Los Angeles is 301 CPM, or 2500 nSv/hr. The are “Expended” unless you are exposed to a dirty bomb.. with more material than can be burned-up in the blast. Next to the door into the storage facilty – 25 feet from my desk – it reads 33.05 X1000. On average, our annual radiation exposure from all natural sources is about 300 milliRem, which is equivalent to 3 milliSieverts (3 mSv). What did you mean by this? Ear lobes are the highest (most blood ?). for example, he suggested that if there was sufficient air flow “out” of the home/local, it would “carry off” some. i live on maui and have for 35 years. How can I find the gamma ray particle. Question. Where I work (Mineralized Core storage Facility) I am exposed to may levels of radiation (from pitchblend) – is there an easy way to come up with a exposure dose? As for the measurement unit, Geiger counters simply measure the counts per minute (CPM). What danger am I in if I wear the watch regularly? Models include Ecotester, SOEKS 112, 01M, Ecovisor F4, Quantum. Revelation 16:3 in the ocean water and that for the last week there radiation reading has tripled from the normal reading they get. Assume a commercial airline pilot flies at a ceiling of 40,000', and at that altitude, where cosmic rays are more intense, receives a dose rate of .3 mR/hr. with most sites across the U.S. at elevated readings averaging between 150 – 200 CPM. Any experts would teach me whether the reading of 0.12 uSv/h is safe? So, we have radiation level readings, but is there any way to get readings on WHAT is coming over here? Assume the dose rate from a granite countertop in a kitchen is .05 mR/hr. Others are not. But usually much lower. We work around this stuff every day. In short, no. Does this post mean that the radiation has reached the East Coast? You can check out a radiation safety textbook, read a few hundred pages and everything is explained in detail. I have had no radio therapy. The units of ‘rem’ and ‘sievert’ relate to biological damage done to human tissue. Lots of various opinions about thresholds, etc…. My family and I want to know where the safest place to live would be. – I am now stepping off my soap box. Most Geiger counters are calibrated to Cs137 (Cesium), a radioactive isotope. I think we’re OK for now. We live on a radioactive planet get used to it. I marveled at it for a moment and then ran in, swam around without knowing it was harmful. I have been thinking about what you said, I was really shocked at these huge numbers thinking that my aching was because of these high numbers. SOEKS is the leading manufacturer of top-rated Geiger Counters, Nitrate Food Testers and EMF meters. Yeah I think Fukushima is about 10,000 times worse, And that’s if it’s just uranium if the Mox fuel – plutonium gets involved and it’s about 2 million times worse I’ve heard. 259 (at 10,000 CPM). On March 18, Japan’s science ministry measured radiation at 18 locations in areas 30 to … 1.) Watching the geiger counter rate against time and compairing to the background level seems a good way to go. All of the others, range 2 through 10, mean other things having to do with the isotopes themselves. Some are incredibly sensitive. Then multiply the dose rate, expressed in mR/hr, by the number of hours of your exposure over the course of a year. 7/24 78,648,600 83,059,359 Raleigh, NC. After having a medical test mri with contrast my cpm went to 29000 for 1 day a few months later after a stress test with contrast my cpm count was over the 65,000 limit on my Geiger counter for 1 1/2 days is this normal …, You people are all fools if you believe any level of man made radiation is safe. This is more than 300 times above normal and 17 times higher than the pocket of radiation we ran away from the day before. Assume the dose rate from a high grade, 1" radioactive sample of Uraninite equals 100 mR/hr. Radiation dosage is a measure of risk – the biological harm that tissues receive in the body. Microsieverts, one millionth of a sievert and abbreviated as uSv (1,000,000uSv = 1Sv)Do… and how dangerous is this…. This is the main reason for these units – to factor the differences in damage that is caused from one type of radiation to the next. 7/24 57,573,062 In cases of high-radiation fields, the Geiger tube can saturate, causing the meter to read a … Sitemap | Tiger Electric Inc in Brea, CA | Photos | Reviews | 335 building permits for $571,300. Steve, I would have actually found that fun and interesting to see in person. The cores of reactors 1, 2, 3. are in the EARTH… they are now running free and are radioactive steam volcanoes! We’ve also tested local produce. A half life is the amount of time it takes for a radioactive element to lose half its energy. This is called a “red tide” Harmful algal blooms, or HABs. FWIW there is NO “safe” dosage of non natural radiation. I bought the GQ GMC-300E Plus, a nice little Geiger counter, to test the levels around my cat who would be having I-131 treatment for her hyperthyroid condition. Assume close proximity to the countertop of 3 hours per day, or 1,095 hours per year. Some are high quality. CPM readings are not necessarily consistent from one device to another. I am new to Geiger Counters. @Jack, you need to look at this one: “Beta Gross Count Rate (CPM): 17”, which is near the top of the list for each station. Does anyone know what is going on? Question. 2.) I’m an airline pilot and would love to hear your take on this: I would say pilots and airline stewardesses will be developing radiation sickness in 5 to 15 years, cancer risk is already way up. “Acceptable levels”have been raised everywhere. 7/24 25,724,470, SUPPORT MSB at no extra cost to you: So, let’s use the number 100, since this is the threshold that the Radiation Network website has chosen. Most background I have here in Medford Oregon is about 35 – 40 cpm. they can’t tell anyone things are not fine, would not be able to keep the roads open. Do we know if its Iodine or Cesium or Plutonium? Also note kerosene fires and older 747’s aren’t a good idea if the DU is atomized. 86 (at 500 CPM) It has held candy and cookies and now holds the bills. Technically, “It is the number of atoms in a given quantity of radioactive material that are detected to have decayed in one minute.”. 3.) Not to mention using our ocean as a dump ground for toilet waist and other very nasty chemicals. The whole unit is bullet resistant, (U.L. Week of July 24, 2020 bad enuf you need to make sure you have your iodine in and keep iron levels up for starters.. as you pack to leave…which will put it off for a whileif you can get out of the direct wind currents. Rob, nuclear phenomena are complex, as are many topics in science- there are semantics and the different quantifing words mean different things as far as energy, absorbed dose, etc. There is over whelming proof from Govt testing many years back and recently that the smallest amounts of exposure to man made radiation will always give humans and animals cancer… no natural radiation can ever give you cancer and that is how they fool all of you into thinking it’s the same when it is totally different and toxic to all living animals… What is the normal background and what do I do with my wifes dish without being thrown out of the house? What we really know is all radiation is dangerous to breath and eat. Advertise a week or two ago, an employee of the non profit whale sanctuary organization in kihei, maui All of America is downwind from Fukushima, and since October 2013, we’ve got the radiation count to prove it. Exposure to radiation can cause cancer. Kale and tomatoes grown in various areas in southern and Central California. 7/24 72,873,751 :-). Not only from Fukushima, but also from the many, many and I mean many radiation dumps we and other countries have done. (detected by GQ GMC-300, Geiger Muller Counter, for 60 seconds, on sea food.) “The cores of reactors 1, 2, 3. are in the EARTH” Keep in mind please that these risk levels explained above reflect external exposure to radiation and do not address what happens when radionuclides lodge inside the body after being inhaled or ingested. What I’d like to know is just how hot 80,000 CPM is?? I have never been given any training on evaluating or interpreting this radiation monitor. Contact Us Steve, The workers that were working on the equipment used compressed air to blow off the equipment. For example, the CPM readings that you might see on the Radiation Network Map or elsewhere. I witnessed H bomb test “Bravo” in March 1954 aboard the USS Gypsy ARSD-1. Exposure measures the effect of radiation on substances that absor… The G-M counter is one of the oldest radiation detector types in existence. 1 rad = 0.01 gray (Gy)1 gray (Gy) = 100 rad, 1 rem = 0.01 sievert (Sv)1 sievert (Sv) = 100 rem. Some isotopes will remain radioactive for a longer time though. The tube on a quality Geiger counter will typically be several times larger than the tube on a cheaper Geiger counter (for example). Any advice most appreciated. 2.) I just realized that you are talking about readings that were taken on Jan 4th but Jan 4th is not here yet? I tested the Geiger counter at home and at work and in all kinds of rooms, granite counter tops, and the CPM was low (0-50 is background). So as we stand right now we are not sure what these results mean. The following explanation focuses on SI units. At this time (79 yrs. Fish from Japan, Hawaii, Washington state, Santa Barbara, Alaska, the Atlantic and North Carolina. If you could go anywhere on the East Coast for safety where would you go and where do you reside now? for example, the expert suggested we drive by the home several times day of when he was coming to test, to check and make sure the sellers were not leaving all windows open, maybe even with fans, to increase air flow and “reduce” any levels. I have an arduino based Geiger kit running an SBT11A GM tube. You are probably shielding some of the regular background radiation with the seafood. We measure "activity" and "exposure". Pattie ,,larry,,,anon,,,have any of you ever been to fuku ?have you ever worked with nuke s ? Thanks. Well, these readings do not seem to be coming down with a drought, so it can’t all be rainfall radon anymore (which is typically over 1200 CPM). You work at a decontamination project and you aren’t issued one? Whenever X1000 is shown above the numeric display, multiply the displayed reading by 1000 to determine the radiation level. The following information may help you understand Geiger Counter Readings, the units of measurement for Geiger Counters (nuclear radiation detectors). Stop by my house any time if you do not believe the readings. The unit of absorbed radiation dose is the sievert (Sv). Privacy Policy Conclusion: The Geiger Counter readings that one may experience can be compared to the equivalent ‘what-IF’ scenarios listed above for potential health impact. Who knows after that. Also different at various latitudes because atmosphere depth changes with latitude. It’s not done on purpose. 3.) Background averaging about 36 cpm. This is to maintain the pressure sensor , changing the settings for the low level switch or adding the setting for a output flow meter . 104 were burned in #4 reactor.. 40 additional ones burned in #4 pool while SITTING IN WATER… due to no borination and low water level events. I have done extensive research on this subject and I would have to say that I don’t think alpha particles are the most damaging. With fluctuations to 14,000 CPM and more. The input menu will have all available inputs. Previous news Next news So as we stand right now we are not sure what these results mean. 3.) A Geiger counter is an instrument used for detecting and measuring ionizing radiation.Also known as a Geiger–Muller counter (or Geiger–Müller counter), it is widely used in applications such as radiation dosimetry, radiological protection, experimental physics, and the nuclear industry.. at the time of house purchase we did a fair bit of research, and honestly snuck the “tester” into the previous owners garage (he had labelling on his vehicle, so we did not want the neighbours etc to become alarmed). Do you still “think we’re ok”? etc…. Is this normal or are there radiation clouds in the upper atmosphere from Fukushima? Is this a safe level? But with enough voices, you can have a beach. If left on continuously, the batteries should last about a week before needing replacement. Related article:5 Geiger Counter Radiation Detectors. RadNet Total Gamma Radiation Data (TGR) NorthEast US Coast Feel blessed to have lived this long (lot’s didn’t) brother died at 51 from stomach cancer, but would like to have someone explain in dummy’s language what 1000 to 2200 mrems mean to a human body. The Readings are then annualized and compared with the same city Gamma Readings for 2019. Where on the East Coast is safest? Here are the results (in Grays, which are a unit of size, not of the effective dose received by people in the area). However for general purposes I consider them the one and the same. Furthermore, Chris Busby and others have documented very thoroughly that the risk model explained so carefully above is flawed (no discredit to the very helpful efforts above)and lacks predictive value. I would guess all that is contaminated as well ! We are all contaminated! I live 10 (ten) miles from the Pacific in central California. As a kid, I went to church, and still do. Rad and Gray are ‘absorbed dose’ units.Rem and Sievert are ‘equivalent dose’ units. TABLE TO CONVERT GEIGER COUNTER READINGS TO CPM TO ANNUAL OR LIFETIME EXPOSURE LEVELS ‐ Shaikh Jalal Ahmad Units Meter reading (take average of at least 3 minutes of counts) Conversions: cpm 10 20 30 60 100 150 200 300 cpm to mR/hr divide cpm by 1500 to get mR/hr cps 0.17 0.33 0.5 1 1.67 2.5 3.3 5 Attn Tom: Hey, I’m former C-130 flight-crew, and I can say this is within normal range, especially at higher altitudes. Is this a normal reading? My dogs have died. The µSv (microSievert) is an internationally accepted unit for tissue dosage. What are your reactions to the reported increase in birth mortalities & alarming findings in food, water & milk…at this late date & after my above possibly flawed reasoning. Shopping Cart Software by Bigcommerce, The following data is from an industry source believed to be reliable. No, but it may enable you to escape a contaminated area, and therefore continue eating. It is really measured in amount of exposure per hour. There may be other reasons such as pollution or algae swells or something like that. At least I can now send the bills back with a little zip to it. The CD V-700 is a Geiger counter employing a probe equipped with a Geiger–Müller tube manufactured by several companies under contract to US federal civil defense agencies in the 1950s and 1960s. Also, the body mistakes radioactive iodine for the stable form and essentially sucks it up in the thyroid. This chart is much clearer on the website. Last modified: March 22, 2011 at 6:15 pm At 4:30 PM on 3/20/14 the RADNETWORK website had no readings over 55 on their U.S. Continental map. Radiation levels in the areas surrounding the crippled reactor vary wildly from day to day and place to place. @Luanne, There are a multitude of sources available by doing a Google search. ps – the monitor is “Inspector Alert – Nuclear Radiation Monitor”. Ecotest MKS 05. requirements sought after by the larger banking customers; Appears frameless, greatly improving the appearance of the lobby; It is easy to move or reconfigure, as the clients needs change 4 (at 10,000 CPM), Days for earliest onset of radiation sickness: you might find, the wife’s pottery is not your only home / yard exposure source. they fully melted down. My wifes freaking out. i have a geiger counter but am lost on how to read what is harmful or not. 42,185,407 New York City, NY. These are more universal units of measurement that can help you better understand your radiation exposure. Except for my wifes favorite pottery dish that reads 120 cpm. Gamma radiation Counts have shot up as much as 21.59% in the last week. iOSAT Potassium Iodide Tablets(view on amzn), CPM abbreviates Counts Per Minute and is a measure of radioactivity – a unit of measurement seen on some Geiger counters. Assume a Sherpa living in Tibet at 12,000', which high altitude means less atmospheric and electromagnetic shielding of cosmic rays, receives a constant dose rate of .04 mR/hr. A Geiger-Mueller counter is one good example. @Gelaine, Although apparently currently very low readings, we might expect to see Iodine-131, Cesium-137, and possibly Plutonium-239, based on the fuel that had been used in Fukushima. It can also be affected greatly (spikes) by sun-spot activity. I have a CD-700 and I get 50 clicks per minute, when it clicks it will move the needle half way up the meter scale set on times one. That everyone has already blown through their typical 600mrem & even their harmful 1200mrem by now sample. Her there a few radiation facts and numbers regarding dosage 10:39 am question on my table.
