Patent ID: 7049599

Claim:
A radiation detection 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 means for counting; first means positioned on said probe for, in a first state, remotely causing said means for counting to accumulate a scintillation count over a first period and, in a second state, remotely causing said means for counting to accumulate a scintillation count over a second period, said second period being longer than said first period; and second means positioned on said probe for causing, upon activation, said output means to manifest an accumulated scintillation count from said count means, wherein said first means and said second means are mounted on a carrier that electrically isolates said first means and said second means from said probe, said carrier being releasably attached to said probe.
