Professional dosimeter-radiometer MKS-151.

Dosimeters, radiometers, roentgenometers and other similar devices.The professional dosimeter-radiometer "MKS-151" has been produced presumably since 1993. The device is designed to measure the equivalent dose rate (DER) of photon (gamma) radiation and the flux density of beta particles. DER measurement range 0.10 ... 99.99 μSv / h. The error is no more than 15%. Flux density measurement range 0.20 ... 99.99 beta freq. / (s.cm.kv). The error is no more than 20%. Power supply - battery of the "crown" type. The overall dimensions of the device are 46x76x169 mm. Weight 0.5 kg.
