stock here: Simple: He is using the EPA reports that include very sensitive gamma radiation reading (in 8 different energy ranges incidentally), compared to radnet which is comprised of VARIOUS Geiger counters, that are catching some Alpha, but mostly beta and gamma and they are not as sensitive. So a CPM means little unless you the type of Geiger that took it Granite Countertops: 1.) Assume the dose rate from a granite countertop in a kitchen is .05 mR/hr. 2.) Assume close proximity to the countertop of 3 hours per day, or 1,095 hours per year. 3.) Therefore, annual dosage from the granite equals 55 mR (.05 mR/hr x 1,095 hours per year) Models 106B and 107B are battery operated Geiger Counters. These instruments have three scale ranges; 0.2, 2, and 20 milliroent-gens per hour (MR/HR) and employ Geiger tubes as detecting elements. The presence of radioactivity is indicated by a meter, a neon light and through an earphone. The Model 106B detects Beta and Gamma radiation. It is.

you also can get very high reading from smoke detectors with some Geiger counters all readings of background radiation should be done in the open and from the same point every time. I use to prospect for uranium back in the 1970s. The highest reading i ever got in a home was a old grandfather clock. The clock face was over 1000 counts per minutes On the one hand, we might use a Geiger counter to perform a radiation scan of a suspected object or situation, and in a weird sort of way, we want a hit to confirm our fears, but on the other. Geiger Counters. When it comes to Geiger counters there are many to choose from, some are hundreds of dollars, and some can be as low as $25. Generally, the lower the price of the Geiger counter, the lower the sensitivity. I am going to focus on some low cost, but affective items

For the most part they rely on the serial output of the FTDI connector. (Sorry if you find this PC centric, it's what I have.) The Gamma-Scout geiger counter has a large digital display that can display the radiation detected as dose rate (µSv/hr or mRem/hr) or in pulses (total count or per second). There is also an analog logarithmic bar chart to quickly visualize the magnitude of the measured dose rate

Radiation exposure: a quick guide to what each level means

However the Geiger counter can measure counts but not the energy of the radiation, so a technique known as energy compensation of the detector tube is used to produce a dose reading. This modifies the tube characteristic so each count resulting from a particular radiation type is equivalent to a specific quantity of deposited dose A very good video with excellent demonstration just to know some basics about how a Geiger Counter works. Other thing for consideration is a chart with the CPM over time on Tokyo. The first chart correspond to the levels registere in the past hours.. the chart is constantly updating.. bellow this one is the Reference Chart In this investigation the scintillation counter was not calibrated and the readings are merely relative measures of radiation intensity. The Geiger-Muller counter employs a gas-filled tube which reacts to about 1 percent of the gamma rays that penetrate it. The Geiger-Muller counter used in this investigation has two devices for indicating. When I was unable to find any published real-time data for California radiation levels during the Japanese meltdown in March 2011, I bought my own Geiger Counter to take my own readings and protect my family, especially if we needed to evacuate to Nevada.. Once I had this data, I realized that everyone else in California was curious, too, so I publish the levels here

Among other possibilities, Geiger counter malfunctions, proximity of the counters to certain medical procedures, radioactive items and natural ocurring background levels (Ex: Radon) can cause high readings at a Monitoring Stations. Always refer and rely on your local Radio and TV stations for informatio Checks radiation levels in your home, food, water, and surroundings.

If you take this radiation stuff at all seriously, then get a Geiger Geiger Counter guide for testing the environment, goods, and food, for Radioactive Contamination! (Do not just rely on this document, do more research, it is only meant to be a basic guide.) The CPM to uSv/hr conversion in the chart above is based on the pictured GammaScout Geiger counter tub • µR/hr (MicroRoentgen) - displays the radiation level from 1 to 9999. Once the levels exceed 9999 µR/ hr, the unit of measure will change to mR/hr. Once the radiation levels go below 9999 µR/hr, the unit of measurement will revert back to µR/hr. • µSv/hr (MicroSeivert) - displays the radiation level from .01 to 1000 The high radioactive readings commenced after the 5 mph North wind dropped to zero mph. Our best guess based on the area under the curve in the Weibull chart we used, is that the Geiger counter's exposure at the Geiger counter was about 21 millirems, about 2 chest x-rays. Of course the Geiger counter did not inhale anything, no telling what.

The highest readings registered 4 R/hr (Roentgens per hour), high but not alarming (a lethal dose is 500 R/hr over 5 hours). But the Geiger counters they were using only went up to 4. The real reading was 20,000 R/hr and unprotected workers received fatal doses in less than a minute. It took two days to order the evacuation of Pripyat, the town. The high uranium content causes relatively high readings on the Geiger counter. Because of its elevated uranium, the Heebner is more radioactive than the overlying Kanwaka Shale and the underlying Lawrence Shale which are gray shales. However, both black and gray shales have radioactive sources of thorium and potassium and contrast with low.
