Wide Area Alpha Scintillation Monitor

Wide Area Alpha Scintillation Monitor [ TYPE : AM 736W ]

Technical Data
manual

It is primarily used for routine checking of Alpha contamination on floor, work benches, walls and beams etc. in active labs. Also facilitates counting of wipe samples, air activity samples etc. It is amicro-controller based unit designed to indicate contamination in CPS or CPM or counts for a ‘preset time’ to indicate on LCD display. It has large sensitive area of about 125 Sq.Cm. It operates on 6V, dry cells. Well designed ‘handle’for holding the unit hasbeen provided.
