geiger counter units safe levels

new solar system on existing commercial roof-top. 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). A multiplication factor (radiation factor) is used that represents the ‘effective’ biological damage of a given type of radiation. Gamma radiation Counts have shot up as much as 21.59% in the last week. 87,824,984 Portland, ME. 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. Any advice most appreciated. The hypothesis is that a Geiger counter can be built and the accuracy of the measurement was comparable to a commercially availabl… NNormal background levels are very low; 3x very low levels are still very low levels. This allows the polluters a smoke screen to hide behind and geiger counter businesses to pop up everywhere. 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. Measuring the radiation level in … The Cs137 calibration factor listed above (120 CPM) was converted to obtain the proper factored results listed below (0.83x). It was not a CPM measurement, MR/hr I think. the effect it has on human tissue, which is measured in sieverts, abbreviated as Sv.As 1 sievert represents a very large dose the following smaller units are commonly used; 1. Strontium is confused with calcium and is embedded in bones. when your levels fluctuated, were there increases in air flow – fans/air conditioning/windows – doors open? 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. Remember the digital geiger counters ar137 radioactive e calibrated using a Cs-source. Recently we removed a trailer load of materials from work. Assume 20 hours of flight time per week, or 1,040 hours per year. 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. might not. Fiestaware production did not include uranium or red again until 1959. Other foods that have above-average levels are potatoes, kidney beans, nuts (especially brazil nuts), and sunflower seeds. The higher we go, the less our atmosphere protects us (as if we didn’t have enough to worry about). Crazy thing about it is that we have had it for about 25 years. The source of the radiation is the radium 226 in the lume that was outlawed in 1960’s in the manufacture of wristwatches. 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. This is more than 300 times above normal and 17 times higher than the pocket of radiation we ran away from the day before. Over the days and weeks her CPM numbers went down into the 600s finally and then the 300s and lower. period.. Older than that uptake is limited because our body’s slow down. The PTB are psychopaths for doing this to us. Given that 365 days a year x 24 hours per day equals 8,760 hours per year of exposure. have a few question in mind, and ask each of them, sort of give them to understand you might hire them, but for now just getting info. Building a Geiger counter was my project to prove that a simple Geiger counter can be made so it could detect radiation. I conclude that everyone has already blown through their typical 600mrem & even their harmful 1200mrem by now. What we really know is all radiation is dangerous to breath and eat. Therefore, annual dosage from the radioactive ore equals 200 mR (100 mR/hr x 2 hours per year). I marveled at it for a moment and then ran in, swam around without knowing it was harmful. Privacy Policy All the available data seems to be related to radiation entering the body but not much about an irradiated body aside from radiotherapy related cases. For this, the purchase of a radon detector with an activated carbon filter. But a quick reality check on the safe levels of radiation we absorb every day might at least help some people save a few dollars on a Geiger counter. Alerts. The following information may help you understand Geiger Counter Readings, the units of measurement for Geiger Counters (nuclear radiation detectors). Interesting fact:All food sources combined, expose a person to around 40 millirems per year on average.Many foods are naturally radioactive, and bananas are particularly so, due to the radioactive potassium-40 they contain. The unit of absorbed radiation dose is the sievert (Sv). mica is opaque to radiation. Radiation dosage is a measure of risk – the biological harm that tissues receive in the body. Higher freq gets there faster. As a kid, I went to church, and still do. Therefore, annual dosage from the granite equals 55 mR (.05 mR/hr x 1,095 hours per year). @Luanne, There are a multitude of sources available by doing a Google search. It’s not done on purpose. Therefore, annual dosage from the granite equals 55 mR (.05 mR/hr x 1,095 hours per year). Oh yes I forgot to mention this is in a building outside of the building I get zero counts per minute. Almost all States have had sustained CPM’s of just the CS-137 of 50 or above. Related article:5 Geiger Counter Radiation Detectors. High accuracy geiger counter, radiation detector with Dosimeter: RADEX 1503+ Radiation Detector(view on amzn). Thus at 3cms the reading was 8.8µSv/hour, at 4cms: 5.0µSv/hour, at 8cms: 1.24µSv/hour, at 12cms: 0.56µSv/hour. 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. Do we know if its Iodine or Cesium or Plutonium? Assume close proximity to the countertop of 3 hours per day, or 1,095 hours per year. Most Geiger counters are calibrated to Cs137 (Cesium), a radioactive isotope. I can find no net data regarding human body output. – I am now stepping off my soap box. Assume the dose rate from a granite countertop in a kitchen is .05 mR/hr. At least I can now send the bills back with a little zip to it. Revelation 16:3 The EPA’s website shows the GAMMA GROSS COUNT RATE (CPM) in Anaheim to be in the 3000 range. 3.) Many thanks in advance. This is called a “red tide” Harmful algal blooms, or HABs. should we be worried out here in the hawaiian islands? when we bought our last house, it had some lovely stonework on fireplace. We are looking at places on the East coast such as Vermont, Upstate NY, Maine and New Hampshire. 7/24 78,648,600 83,059,359 Raleigh, NC. My family and I want to know where the safest place to live would be. 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 Although most vaseline glass sites maintain that it is perfectly safe (unless ground and ingested), I have my doubts. 1,729 (at 1,500 CPM) Advertise 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. You didn’t post what measurement scale CPM, mR/h or uSv/h. 1. There were MOX rods there.. but also full rods of Plutonium… BREEDER RODS !!! 24/7 drinking water, swimming to set buoys, eating food cooked with water, handling items salvaged and more. 752 Level 3) It meets LEEDs guidelines and gains LEEDs points; Meets current seismic Ca. Is this a safe level? The workers that were working on the equipment used compressed air to blow off the equipment. that doesn’t mean that you shouldn’t still wash off well after getting out of the ocean. Keep changing that filter everyday? My wifes freaking out. 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. Could you give a reference for the increase in cancer rates related to radiation? The ocean has limited life remaining. 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). As it turns out though the earlier production runs were the only ones using natural uranium. hunt around for some local or state experts who do this sort of testing. The readings came back 539, 575, 668 and 1077 (cpm). 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. 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. The highest I ever got was 30 or 33 CPM. I drove home from the vet for 2 hour trip with my kitty in her carrier on the seat next to me, and tried the Geiger counter around her at home. Detects gamma radiation at levels as low as 0.1 megaelectron volts; Accurately reads radiation levels in 20 seconds; Simple enough for a child to use, but as accurate as professional-grade equipment; Reads accumulated dose for total exposure; Utilizes the same SBM20-1 … 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. 1 rad = 0.01 gray (Gy)1 gray (Gy) = 100 rad, 1 rem = 0.01 sievert (Sv)1 sievert (Sv) = 100 rem. Except for my wifes favorite pottery dish that reads 120 cpm. My dogs have died. There may be other reasons such as pollution or algae swells or something like that. 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. We are all contaminated! I have an arduino based Geiger kit running an SBT11A GM tube. Station ID 6:2434132255 Fukushima Dai-ichi MP-6, Fukushima, JP nSv/h: current 2500 Low 2400 High 2800, 2.5 x 120 CPM = 300 CPM = 2500 nanoSieverts/hour, I remember as a kid on the beach of Santa Cruz CA the surf was red. 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. Dont worry, the govt raised the safe allowance level, so we’re all good lol. Geiger counters can only detect the presence and intensity of radiation. Didn’t know what to do. Our tests are showing 30 to 50% above back round. CPM readings are not necessarily consistent from one device to another. Experiments with the Geiger counter Who knows after that. Exposure measures the effect of radiation on substances that absor… 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. RadNet Total Gamma Radiation Data (TGR) NorthEast US Coast Most background I have here in Medford Oregon is about 35 – 40 cpm. Do you know of any such device? It has held candy and cookies and now holds the bills. I am now sitting here writing this note and see it spiked up to 65. 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.
