ALPHA SCINTILLATION MONITOR [Type : AM736]
Technical Data
ALPHA SCINTILLATION MONITOR Type : AM736 Alpha Scintillation monitor type AM736 manufactured and supplied by NUCLEONIX SYSTEMS is designed around 8 bit microcontroller. It uses a ZnS (Ag) screen as the alpha scintillator which is covered with a thin aluminized mylar window to prevent light leakages. Efficiency better than 25% at centre is guaranteed with background counts being less than 1CPM.
It is primarily used for routine checking of Alpha contamination on floor, work benches, walls and beams etc. in active labs. It is a microcontroller based unit designed to indicate contamination in CPS or CPM or preset scaling modes on a LCD display. It has large sensitive area of about 100 Sq.Cm. It operates on 7.5V, dry cells. Well designed handle for holding has been provided the instrument.Features
