geiger counter units safe levels

A multiplication factor (radiation factor) is used that represents the ‘effective’ biological damage of a given type of radiation. We are looking at places on the East coast such as Vermont, Upstate NY, Maine and New Hampshire. CPM = 33,050 At least I can now send the bills back with a little zip to it. Thanks for your advice in advance. Stop using the toilet? This is more than 300 times above normal and 17 times higher than the pocket of radiation we ran away from the day before. 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). It can also be affected greatly (spikes) by sun-spot activity. The cores of reactors 1, 2, 3. are in the EARTH… they are now running free and are radioactive steam volcanoes! had a nuclear stress test with contrast … tested my bodys radiation with Geiger counter first day over 65000 cpm that was the most my Geiger counter would read … took some zeolite count was normal in 2 days … is 65000+ cpm,s normal for a nuclear stress test ? a) wear lead underwear, don’t think aluminum will cut it. How to calculate your annual radioactive dosage or exposure: First measure your dose rate using a Geiger counter that reads out in mR/hr. Is this a safe level? 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. 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). in the ocean water and that for the last week there radiation reading has tripled from the normal reading they get. Adding man-made sources (medical procedures, and others) the average annual U.S. radiation dose is about 600 milliRem, which is equivalent to 6 milliSieverts (6 mSv). Apparently the radiation concentrates in the ditch. b) I seem to recall, that the expert we hired, stated that specific in home levels will / can vary, depending on air flow. I was considering to start collecting antique vaseline (uranium) glass. Original measuring unit for expressing the absorption of all types of ionizing radiation (alpha, beta, gamma, neutrons, ... what radiation exposure level is considered safe. Nobody knew and no government to tell the people it is harmful. Anyone experience this? rene says: September 23, 2013 at 10:39 AM For example, one chest X-ray will result in about 0.2 milliSievert (mSv) of radiation dose. Here are the results (in Grays, which are a unit of size, not of the effective dose received by people in the area). Assume the dose rate from a granite countertop in a kitchen is .05 mR/hr. 30,001,738 Yaphank, NY. 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. 4 (at 10,000 CPM), Days for earliest onset of radiation sickness: 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. The readings came back 539, 575, 668 and 1077 (cpm). Therefore, annual dosage from the granite equals 55 mR (.05 mR/hr x 1,095 hours per year). its worth pointing out that CPM can be misleading UNLESS you know how the device is calibrated. 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! 3,600 μSv – Average radiation a US citizen receives in a year from all sources. Assume the dose rate from a high grade, 1" radioactive sample of Uraninite equals 100 mR/hr. TGR CPM Annualized City, State Date Read 2019 TGR CPM Recently we removed a trailer load of materials from work. So comparatively it will always pick up a larger CPM value. Almost all States have had sustained CPM’s of just the CS-137 of 50 or above. Exposure measures the effect of radiation on substances that absor… https://www.veteranstoday.com/2020/07/24/gamma-radiation-in-america-2020-8b/ 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. Values on our radiation monitors are displayed in both mrem/hr and µSv/h. These meters are available in different units, including mR/hr, or milli-Roentgens per hour (popular in the US and Israel), and µSv/hr, or micro-Sieverts per hour (popular in Canada and overseas ). get wife to chuck it. if you use a DIFFERENT, more sensitive geiger in the afternoon and get 1000cpm that isn’t comparable as you are not comparing like for like. Background averaging about 36 cpm. 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. We measure two general phenomena when we discuss radiation. Next to the door into the storage facilty – 25 feet from my desk – it reads 33.05 X1000. 2.) 1 rad = 0.01 gray (Gy)1 gray (Gy) = 100 rad, 1 rem = 0.01 sievert (Sv)1 sievert (Sv) = 100 rem. Activity is basically just how much radiation is coming out of something, whether it's particles or waves. It immediately started crackling like fireworks, and alarm beeps went off and it climbed into the hundreds, and very fast up to 2,490 CPM at which point I backed away in a panic. The following information may help you understand Geiger Counter Readings, the units of measurement for Geiger Counters (nuclear radiation detectors). All it has to do is score tracks through tissue enough times to cause a cancer. Being that I am new to all of this, I took an hour background test and came up with 38.166. Shielding(alpha: nearly anything… a sheet of paper will stop it – danger of breathing it)(beta: wood, water, plastic-acrylic, aluminum)(gamma: water, concrete, lead). Thank-you for this article. Most Geiger counters also have an audio readout that sounds one "click" for each particle count. Is this a normal reading? I will do my background test again. Our tests are showing 30 to 50% above background. I thought that these looked like huge numbers, but then I divided down into literal CPM and got 17.7 CPM for Portland, ME for the year between July 24, 2019 thru July 24, 2020. Of course the vet keeps her there a few days until her level is “safe” enough to go home. Watching the geiger counter rate against time and compairing to the background level seems a good way to go. Ear lobes are the highest (most blood ?). Back round averaging about 36 cpm. Pattie ,,larry,,,anon,,,have any of you ever been to fuku ?have you ever worked with nuke s ? 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). Gamma radiation Counts have shot up as much as 21.59% in the last week. Last modified: March 22, 2011 at 6:15 pm 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. However, you should verify the following government data - research the NIH  (. Tiger Electric Inc in Brea, CA | Photos | Reviews | 335 building permits for $571,300. Fiestaware production did not include uranium or red again until 1959. mR/r = 33,050 … he said he suggested this, just in case they were aware of any such problems and wanted to reduce readings, if they suspected we were having readings done. The workers that were working on the equipment used compressed air to blow off the equipment. However, after reading this page,I am having second thoughts about this hobby! Therefore, annual dosage from the radioactive ore equals 200 mR (100 mR/hr x 2 hours per year). The experts have told me that “things are fine, just fine.”, Why don’t I believe them? The objective: Why don’t we have radiation monitors in our homes. Radiation levels in the areas surrounding the crippled reactor vary wildly from day to day and place to place. We measure "activity" and "exposure". How can we change it? Why would this guy Bob Nichols use such large numbers when 17.1 CPM is really how many clicks there are a minute? I cannot help but reflect on this verse in the Bible. Models include Ecotester, SOEKS 112, 01M, Ecovisor F4, Quantum. A half life is the amount of time it takes for a radioactive element to lose half its energy. The highest I ever got was 30 or 33 CPM. I know I am posting a lot of posts, but I just measured my air filter and with a normal background of 38cpm I read 340cpm. If you’ve heard that Fiestaware is highly radioactive then you should know that it isn’t a myth. So, how do we correlate CPM numbers with ‘badness’? As a kid, I went to church, and still do. This is called a “red tide” Harmful algal blooms, or HABs. Although most vaseline glass sites maintain that it is perfectly safe (unless ground and ingested), I have my doubts. The vet assured me their Geiger counter is calibrated at some hospital and her level was safe to go home. geiger counter is reading in my lab at any particular instant, so I do notknow the Q factor of the radiation and therefore can not calculate the mrem. As Helen Caldicott tells us, one atom of plutonium could kill over time if lodged in the body near vulnerable tissues. (please realize, I am seriously paraphrasing, due to lack of specifics of memory…grin). 3.) 432 (at 100 CPM) A Geiger-Mueller counter is one good example. Experiments with the Geiger counter 752 Level 1 to U.L. The young people up to their 40s are in danger. 87,824,984 Portland, ME. Sorry. ps – the monitor is “Inspector Alert – Nuclear Radiation Monitor”. I understand that the scale and cpm readings you have laid out here are for air born, but do they also work for food. I conclude that everyone has already blown through their typical 600mrem & even their harmful 1200mrem by now. Pressure senso r input (S1), Low Level sensor input … etc…. What did you mean by this? Assume the dose rate from a granite countertop in a kitchen is .05 mR/hr. Conclusion: The Geiger Counter readings that one may experience can be compared to the equivalent ‘what-IF’ scenarios listed above for potential health impact. Building a Geiger counter was my project to prove that a simple Geiger counter can be made so it could detect radiation. You are probably shielding some of the regular background radiation with the seafood. A Geiger counter for measuring radiation sits on a map of the Fuksuhima area. Yup. Our tests are showing 30 to 50% above back round. Speaking as a wife, I have always totally understood that high levels are NOT a good/safe thing. I took my geiger counter on the plane from Cairns to Brisbane and then Brisbane to Auckland and each time the Geiger counter levels rose from 12 cpm at ground level up to 2,500cpm at 30,000 feet. I saw a clip of a reporter’s Geiger counter with the number 171 on it. Does anyone know what is going on? The one hour total timer sitting next to my desk reads 9. Also, I recall there is considerable on line. It was introduced by Hans Geiger and Walter Müeller in 1928, hence the abbreviation “G-M.” (Note: If a person refers to a G-M counter or detector as a “Geiger counter,” it immediately pegs him or her as a nuclear novice.) Is the Northern part like Vermont, Maine and new Hampshire or Southern? The following data is from an industry source believed to be reliable. There are limits on these. – I am now stepping off my soap box. Digital Geiger counters can usually detect 1 to 200 milliroentgens per hour (mR/hr), although more expensive devices can reach up to 1,000 mR/hr. @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. About 7/24 72,873,751 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). An alpha emitter may not give off a super energetic particle but it’s frequency of emission is (most often?) Days to receive chronic dose for increase cancer risk of 1 in a 1,000 The input menu will have all available inputs. This allows the polluters a smoke screen to hide behind and geiger counter businesses to pop up everywhere. There may be other reasons such as pollution or algae swells or something like that. i live on maui and have for 35 years. Some isotopes will remain radioactive for a longer time though. All of the others, range 2 through 10, mean other things having to do with the isotopes themselves. By plodding through the math, we can determine a relationship of Geiger counter numbers versus the risks to your health. But usually much lower. I’m interested in further understanding the level of MOX plutonium headed here and how to logically respond to it. The Gamma Gross Count Rate shows how many gamma rays the monitor detects each HOUR. Therefore, annual dosage from high altitude flights equals 312 mR (.3 mR/hr  x 1,040 hours per year). Didn’t know what to do. Geiger counters can only detect the presence and intensity of radiation. This unit is quite sensitive and can be used to measure low levels of Gamma radiation and detect Beta radiation. The unit defaults to an Auto-off setting but this can be adjusted in settings mode. What type of inhalation exposure did they receive? Older than that uptake is limited because our body’s slow down. Just for fun I hooked the geiger tube up to my cheap USB Oscilloscope (Syscomp Design currently only $189). The higher we go, the less our atmosphere protects us (as if we didn’t have enough to worry about). Not only from Fukushima, but also from the many, many and I mean many radiation dumps we and other countries have done. a nuclear bomb blast gives-off just over 20 short-lived isotopes. pottery is not worth the risk associated with high levels. The lower the better. The unit of absorbed radiation dose is the sievert (Sv). Related article:5 Geiger Counter Radiation Detectors. That depends on how long you are exposed at any given level. I thought that these looked like huge numbers, but then I divided down into literal CPM and got 17.7 CPM for Portland, ME for the year between July 24, 2019 thru July 24, 2020. As for the measurement unit, Geiger counters simply measure the counts per minute (CPM). Can anyone help me understand what that means? After 1943, uranium was disallowed from any civilian purposes as fresh uranium was needed for the War Effort. Previous news Next news I understand the condition is bad!! 5,187 (at 500 CPM) Keep changing that filter everyday? Check ebay. 42,185,407 New York City, NY. It is also about distance – distance is your friend. this is a brief outline. that doesn’t mean that you shouldn’t still wash off well after getting out of the ocean. Fish from Japan, Hawaii, Washington state, Santa Barbara, Alaska, the Atlantic and North Carolina. Ecotest MKS 05. Does this post mean that the radiation has reached the East Coast? It’s possible for one device to have a reading of 150 CPM while another device only reads 50 CPM. 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. I just bought an inspector Exp and am going around the house checking things out. That is well below normal background levels. Mechanics that were working on a dozer that cleaned off an area which contained radiation dust. Oh yes I forgot to mention this is in a building outside of the building I get zero counts per minute. when we bought our last house, it had some lovely stonework on fireplace. 3.) Lots of various opinions about thresholds, etc…. there are herbs you can use…must do full research ..and use with knowledge.. among the things to use are cordycepts…and chorella.. You must know exact procedures…There are several things that can be used.. Cosmic radiation is higher at 30,000′ than at sea level because the atmosphere is thinner and there is less atmosphere above to shield the radiation coming from space. To determine the energy levels of the particles, use a proportional counter. The Readings are then annualized and compared with the same city Gamma Readings for 2019. Do you understand this website? My dogs have died. Any experts would teach me whether the reading of 0.12 uSv/h is safe? So as we stand right now we are not sure what these results mean. We have been dehydrating food samples and testing them for radiation. Also, the body mistakes radioactive iodine for the stable form and essentially sucks it up in the thyroid. T… Stam Peden Except for my wifes favorite pottery dish that reads 120 cpm. © 2020 GeigerCounters.com the KEY thing is to look at the trend and know your meter, if your geiger measures 100cpm on monday morning and then the same geiger measures 500cpm in the same location in the afternoon then you have a problem. Our salvage ship spent 30 continues days in Bikini lagoon salvaging material off the bottom plus hosing down other equipment. Other foods that have above-average levels are potatoes, kidney beans, nuts (especially brazil nuts), and sunflower seeds. For example, the list above shows that a ‘rad’ or ‘gray’ unit of ‘Alpha’ energy that is absorbed by soft human tissue does 20 times more damage than a ‘rad’ or ‘gray’ of Gamma, X-ray or Beta radiation. We have been dehydrating food samples and testing them for radiation. I cannot answer your question but I know who can, some of the folks on No Nukes NW on Facebook have the ability to clarify or steer you to those who can. Geiger counters in the movies start to emit a ticking sound in the presence of radioactivity. I can find no net data regarding human body output. The PTB are psychopaths for doing this to us. Recently there was an radioactive explosion in Nyonoska, Russia. Comparatively, on the NETC website their numbers range from 13 CPM at Lemaire, LA to 569 CPM at Billings, MT. Is this a safe level? But with enough voices, you can have a beach. 2.) Strontium is confused with calcium and is embedded in bones. So as we stand right now we are not sure what these results mean. That seems super low according to this web site’s large numbers. Higher freq gets there faster. Do we know if its Iodine or Cesium or Plutonium? 259 (at 10,000 CPM). Days for earliest onset of radiation sickness 3 x 5,187 = 15,561 /365 = 42.6 years at 300 CPM, Days to receive chronic dose for increase cancer risk of 1 in a 1,000 = 86 x 3 = 258 days at 300 CPM. REM’s are converted to Sieverts at the following ratios:1 rem = 0.01 Sv = 10 mSv = 10,000 µSv Major problem for aircrew and frequent flyers. Thanks. Can we use the same scale you are using to determine what our results are telling us? These are more universal units of measurement that can help you better understand your radiation exposure. and how dangerous is this…. 2.) Exposure to radiation can cause cancer. My wifes freaking out. With fluctuations to 14,000 CPM and more. Isn’t my presumption correct, because none of these “items” fully deplete in less than a month & no-one’s decontaminating or even testing their water, food, shoes, pets, playing fields, streets, sidewalks, stores, offices, houses or cars. 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.. 7/24 25,724,470, SUPPORT MSB at no extra cost to you: The µSv (microSievert) is an internationally accepted unit for tissue dosage. Thanks to the admin and all contributors here for running some good data. even if you do not hire them, maybe you can do what I have with some other situations. It is really measured in amount of exposure per hour. I’ve seen several YouTube videos where air filters were measured and the readings were very high. Got a smatlabs geiger counter for my android for 25$. With 2,500 CPM ( or higher ) of Gamma radiation counts have shot up much!
