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

Features:

availability of a version with a remote beta detector unit, BDZB-09D, or alpha detector unit, BDZA-07D;
smooth adjustment of alarm thresholds within full measurement range;
voice instructional support while measuring;
determination of hand/foot position in the detected area; voice and visual support for correct positioning;
simultaneous colour and sound indication of measurement results;
automatic compensation of external gamma background after every measurement;
alarm if detector units are defective and/or contaminated.

Application:

measurement of contamination level by beta-active materials of personnel’s hands, feet/shoes and clothing and alarm when the thresholds are exceeded;
monitoring contamination level by alpha-emitting radionuclides;
monitoring personnel contamination at NPPs, nuclear fuel cycle facilities, radiologic laboratories and other enterprises that use radioactive substances.
