Abstract

A radiation detecting apparatus comprising means for counting a scintillation count value; means for outputting a scintillation count value to a utilization device; a hand-held probe including a scintillation detector; means for connecting the probe to the count means; and a switch assembly adapted to be removably mounted to the probe. The switch assembly has a first trigger positioned on the probe for, in a first state, remotely causing the count means to accumulate a scintillation count over a first period and, in a second state, remotely causing the count means to accumulate a scintillation count over a second period. The second period is longer than the first period, the switch assembly has a second trigger positioned on the probe for causing, upon activation, the output means to manifest an accumulated scintillation count from the count means.

Claims

CLAIMS:
1. A radiation detecting apparatus comprising:
means for counting a scintillation count value;
means for outputting a scintillation count value to a utilization device;
a hand-held probe including a scintillation detector;
means for connecting said probe to said count means; and a switch assembly adapted to be removably mounted to said probe, said switch assembly having a first trigger positioned on said probe for, in a first state, remotely causing said count means to accumulate a scintillation count over a first period and, in a second state, remotely causing said count means to accumulate a scintillation count over a second period, said second period being longer than said first period, said switch assembly having a second trigger positioned on said probe for causing, upon activation, said output means to manifest an accumulated scintillation count from said count means.
