Universal dosimeter - radiometer MKS -87 "Expert- 3" is designed to :
- Quick search of contaminated items or radioactive sources ;
- Flux density measurement of alpha particles from alpha radiation sources and from contaminated surfaces ;
- Flux density of beta - particle sources and beta radiation from contaminated surfaces ;
- Measurement of ambient dose equivalent rate of photon radiation (hereinafter - DER ) external photon ( X-ray and gamma ) radiation;
- Continuous measurement of accumulation time;
- Continuous measurement of personal dose equivalent (hereinafter - ED) external gamma and X-ray (hereinafter - the photon ) radiation;
Dosimeter is recommended in state regulation to ensure the uniformity of measurements :
- Activities in the field of environmental protection;
- Activities to ensure safety in emergency situations;
- Implementation of the production control of compliance with the legislation of the Russian industrial safety requirements for operation of hazardous production;
- Execution of a secure environment and health.
Dosimeter is a portable measuring instrument .
Dosimeter is bilingual (English / Russian ) inside the settings menu.
Power supply from the built lithium-polymer battery, which is charged via USB-port .
Used counter - "Beta- 2 ."
