"Argh... the lack of units in the descriptions of these photos is driving me nuts! Presumably the meter is set to γ, not β, but it's hard to tell from the photo. If gamma, it looks like the readout is set to exposure rate, which appears to read out in mR/hr (мР/ч). And Googling that brand of meter, "Pripyat" (similar at http://lplaces.com/en/dosimeter/16-devices/67-pripyat-rks20-03), it appears the scale is set to the lower range which maxes out at 2 mR/hr. So, if you stayed put here at 0.6 mR/hr, you'd receive roughly the same dose in 30 minutes that you'd get from natural terrestrial background and other "normal" sources of radiation over the course of a year in the U.S."
- "If that switch on the right is set to "X-dot" then it's in mR/hr. If it's set to "H-dot" then microSv/hr. Hard to tell which from the photo."

1 millirem = 10 µSv 1 rem = 10 mSv = chest scan and then some normal normal = 10-20 microroentgen per hour or, 200 milliroentgens per year / 23 microroentgens per hour elevated reading was 0.3 (per hour?) that's probably 300 micro-roentgen per hour 91 mR/yr == 4milli Sv the russian counter is likely in milliroentgen 0.6mR/hr == 600uR per hour
