Hand-foot-clothing monitor RZBA-07D

Hand-foot-clothing monitor RZBA-07D

High sensitivity monitor RZBA-07D is designed for measurement of contamination level by alpha and beta-active materials of personnel’s hands, feet/shoes and clothing and alarming when the thresholds are exceeded. The monitor is recommended for monitoring personnel contamination at NPPs, nuclear fuel cycle facilities, radiologic laboratories and other enterprises that use radioactive substances.

Reference standards
Nuclear: IEC 61098
