1 DESCRIPTION

1.1 Purpose of use

The RKG-14 "VIRTUOSO" multipurpose environment activity radiometer
(hereinafter called – the radiometer) is designed for
- detection of
objects of the environment;
- evaluation of the detected radiocesium content in the values of specific,
volume and surface activities;
- control of background radiation level in the environment, including
evaluation of the radiocesium emission level as the value of ambient dose
equivalent rate strictly from radiocesium, which is included in the natural
background;
- measurement of volume and specific activities of naturally occurring
radioactive materials
environment.
