The detector is fitted with a bracket to attach to the Model 375-31H. It consists
of a cadmium-located polyethylene sphere surrounding the
3
He detector. A
study has demonstrated that the 9-inch cadmium-located sphere has a response
similar to that of a 10-inch dimeter rem-responding sphere.
See Section 2 for more information on the detector.
A five-decade logarithmic analog output is provided. A battery backup provides
48 hours of additional use after the primary power is removed.
