Measuring Radiation With Geiger Counters Via CPM: How Bad is Bad?
What do the Radiation Network CPM numbers mean with regards to health risk?
With the examples of radiation dose listed above, we can correlate how long it would take to experience those effects based on a hypothetical Geiger counter CPM number.
So, let’s use the number 100, since this is the threshold that the Radiation Network website has chosen. The Cs137 calibration factor listed above (120 CPM) was converted to obtain the proper factored results listed below (0.83x). Higher CPM numbers are also listed for relevancy.
Days compared with the avg. 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 dose for increase cancer risk of 1 in a 1,000
432 (at 100 CPM)
86 (at 500 CPM)
28 (at 1,500 CPM)
4 (at 10,000 CPM)
Days for earliest onset of radiation sickness
25,937 (at 100 CPM)
5,187 (at 500 CPM)
1,729 (at 1,500 CPM)
259 (at 10,000 CPM)
Conclusion: Regarding the radioactive fallout from Japan reaching here to the U.S., the metered Geiger Counter CPM that we see on the Radiation Network can be compared to the equivalent ‘what-IF’ scenarios listed above. Not saying though that anything less would not be ‘bad’ for us, there are lots of theories out there regarding long-term effects of various types of radioactive ionized particles making it into the food chain, etc…
