2.2 Threshold level values of gamma radiation DER in the range from 0 to
5000 μSv/h with discreetness of 0.01 μSv/h are programmed in the dosimeter.
Threshold level value is set automatically after the dosimeter is switched on and
equals 0.30 µSv/h. It corresponds to the maximum permissible level of gamma
background for premises in compliance with the regulatory documents of Ukraine.
2.3 Threshold level values of gamma radiation DE in the range from 0 to
9999 mSv with discreteness of 0.001 mSv are programmed in the dosimeter.
