Radiation averages to know and memorize as an easy guide to your locale
Counts Per Minute CPM
Micro Sieverts per hour uSv/hr
Milli Sieverts Per year
Background Radiation Level Guide for
detections 1 meter above ground
12 0.10 0.88 Average background, pre Fukushima Japan .081 uSv/hr, Australia .17 uSv/hr,
25 0.21 1.83 0.23 uSv/hr world average, USA average 0.34 uSv/hr,
50 0.42 3.65 It is normal to occasionally get short duration peaks above normal background for any location.
60 0.5 4.34 Larger peaks of longer duration indicate detection of a hot spot, or a cloud of radiation is passing through!
100 0.83 7.3 Larger peaks of longer duration indicate detection of a hot spot, or a cloud of radiation is passing through!
150 1.25 10.95 Detections 1.0 uSv/hr and above you are getting into the very dangerous area of detection, shelter or leave immediately!
500 4.17 36.5 Even more dangerous, shelter or leave immediately! Know what your local average background radiation level was

What the scientists use to test airborne radiation from fissionable materials and radionucleides.

And no, I do not recieve any click pay or anything. Just letting you know the play. Was advised that Japanese and US makers of such devices are INTENTIONALLY disabled to make them ineffective in discovering fissionable isotopes in our environment as a control feature to make people go back to sleep. This one is made in Germany. It's what the Universities are using because they trust it. Most US and Japo machines are owned by GE, etc., AS A PARENT COMPANY and GE makes NUCLEAR REACTORS. BE ADVISED.
