1 DESCRIPTION AND OPERATION OF THE PRODUCT

1.1 Product functionality

Dose-rate meter/radiometer MKS-15D "Snegir" (hereinafter - dosimeter) is intended for

measurement of ambient equivalent dose

 

 

(hereinafter - AEDR) of photon radiation and beta particle flux density. as well as for estimation

of count rate at the combined measurement of gamma- and beta-radiation (hereinafter γ + β).

The dosimeter is used for radiation survey at industrial enterprises; in ecological studies;

checking of radioactive contamination of bank notes in banks; radiation measurements in housing

premises, buildings and structures, and adjacent territories, household appliances, clothes, garments,

soil surface of the homestead lands, vehicles.

The dosimeter provides threshold excess alarm signals.
