APPLICATION
Used at VEHICLE (TRUCK) checkpoints.

Detection threshold, no more than:

Cs - 137
300 kBq
Co - 60
150 kBq
Ba - 133

The probability of detecting the reduced masses of nuclear materials is 0.5 with a confidence level of 95%, background intensity of no more than 20 μR/h and a false alarm rate of no more than 1/1000.

Note:

The sensitivity of the gamma channel can be increased by replacing the gamma detector: 4 plastics of 7.1 l;
Can be supplied in a single-rack design;
Can be supplied without a neutron channel.
