Dosimeter - radiometer MKS - 83B "Expert-M2" is intended to :
- Continuous measurement of personal dose equivalent (hereinafter - ED) external gamma and X-ray (hereinafter - the photon ) radiation;
- Continuous measurement of accumulation time and display accumulation time;
- Measurement of ambient dose equivalent rate of photon radiation (hereinafter - DER ) external photon ( X-ray and gamma ) radiation;
- Flux density of beta - particle sources and beta radiation from contaminated surfaces;
- Indication of the density of alpha particles from sources of alpha radiation from contaminated surfaces;
- Quick search of contaminated items or radioactive sources;
- When completing the measuring cuvette - the measurement of the volumetric activity by Cs (gamma ) and Strontium-Yttrium (beta) of samples of water, soil, food, plant products, etc.;
- Indication of the date, time and ambient temperature;
- When connected to a computer - the chronology of events indicating the accumulation of ED and general statistics measuring device programming;
- Graphical representation on the own indicator of stories of the dose rate measuring;
- Measurements area illumination with built-in LED flashlight ;
- When connecting external detection units, the measuring capabilities of the device is greatly enhanced.
Dosimeter is recommended for:
- Field activities in the of environmental protection;
- Implementation of security activities in emergency situations;
- Implementation of the production control of compliance with the legislation of the Russian industrial safety requirements for operation of hazardous production;
- Work to ensure a safe environment and health.
Dosimeter has bilingual (English/Russian ) inside the settings menu.
