The FHT 1372 Radioactivity Monitor is used as a
stationary system for fully automatic monitoring of personnel gates or luggage belts for
entrainement of radioactive sources.
A highly sensitive scintillation detector and the use of ADF (Advanced Digital Filter)
allows extremely sensitive and very fast checking.
The persons or objects may move at normal speed without necessity to stop.By virtue of
the NBR technique (NBR = Natural Background Rejection) developed by ESM, it is possible to
detect small amounts of artificial gamma radiation in the nSv/h range even against a
fluctuating natural background. Additionally an integral alarm level can be adjusted in
order to detect an excessive total dose rate level.
Operation of the monitor is indicated by a green LED on the front of the monitor.
If a radioactive source is detected an alarm is triggered as long as the artificial gamma
radiation is present.
Summary of features
- Very high gamma sensitivity: 20000 cps / microSv/h
- Selective detection of artificial radioactivity with NBR
- No user operation necessary - except reactions to alarms
- Automatic or manual alarm reset selectable
- Easy installation and setup
- Optional neutron monitoring channel
