FCM300 Floor Contamination Monitor

FCM300 Floor Contamination Monitor 

The FCM300 Floor Contamination Monitor is a device for measuring ground radioactive contamination. It uses a plastic scintillator (ZnS:Ag coating), which is sensitive to β/γ rays and a ZnS : AC coating that is sensitive to α rays, thereby achieving simultaneous measurement of x and B/γ rays and displaying the α and β/γ count rates of the contaminated area in real time.

The Floor Contamination Monitor has a higher detection efficiency, improves the sensitivity of the instrument and expands the detection limit.
