Question

What unit of measurement does a geiger counter output?

Answer 1

Most Geiger counters measure radioactivity in several units. A common one is "counts per minute". You will also see measurements in both mrem/hr and µSv/h. The µSv (microSievert) is an internationally accepted unit for tissue dosage. The REM (Roentgen Equivalent Man) was much more common in the past, but is still in use.



1 rem = 0.01 Sv = 10 mSv = 10,000 µSv

1 mrem = 0.001 rem = 10 uSv



=========================



Units of Measurement (Radiation)

1 rad = 0.01 gray (Gy)

1 rem = 0.01 sievert (Sv)

1 gray (Gy) = 100 rad

1 sievert (Sv) = 100 rem

Rad and Gray are ‘absorbed dose’ units.

Rem and Sievert are ‘equivalent dose’ units.
