"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."

Thoughts

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
