The sensitivity of the dosemeter is 1 count per νSv (micro Sievert) and the accuracy is within ±15% from 60keV to 1.25 Mev of X or Gamma radiation.

For example, terrestrial gamma radiation is measured according to general values from 0.03 - 0.3 µSv/h (microsievert / hour).

The map shows "radiation levels of up to ten micro Sieverts per hour in Iitate village, 40km northwest of the crisis-stricken Fukushima/Daiichi nuclear plant, and 20km beyond the official evacuation zone.

The “Area A” (purple color) defines a region with a maximum load of 0.3 micro Sievert per hour.

Area B” (blue) marks a region with 3 Micro-Sievert per hour.

millisievert (mSv): One one-thousandth of a sievert (see also sievert). (millisievert [mSv])

One sievert is equivalent to one joule per kilogram:

The sensitivity of the dosemeter is 1 count per νSv (micro Sievert) and the accuracy is within ±15% from 60keV to 1.25 Mev of X or Gamma radiation.

The unit was named after the Swedish medical physicist Rolf Sievert.

The name is derived from the Swedish physicist Rolf M. Sievert.

The unit for effective dose is the sievert (Sv

During a flight from Paris to San Francisco or Tokyo, aircraft are exposed to an overall dose of about 70 micro-Sievert.

The rem has recently been replaced with the Sievert (1 Sv = 100 rem).

sievert (Sv) is the special name of the unit of equivalent or effective dose.

The unit for committed effective dose is the sievert (Sv
