Model 4200-600 Differential Die Away Active/

Passive Neutron System

Benefits

Capable of the measurement of

·

low levels of fissile and fertile

material in waste

Capable of  both "active" and

·

"passive" operation for the

measurement of fissile and fer-

tile nuclides

Model 4200-600 chamber size

·

will accept waste drums up to

400 litre capacity

The active mode Lower Limit of

·

Detection (LLD) of the model

4200 is approximately 0.61 mg

239

Pu and 0.91 mg 235U

The passive mode detection

·

efficiency for the model 4200 is

approximately 12%
