A radiation detection apparatus having a hand-held radiation detection probe with a switch assembly removably mounted thereon is hereinafter disclosed. The switch assembly having first and second switches, one to initiate transmission of electrical signals representing scintillations detected over a set time period to a remotely located control unit for counting and averaging, and the other to direct the control unit to download and preferably record the counted and averaged scintillation values for further use. The switch assembly has an insulating member for electrically insulating the switches from the probe, and spaced gripping members that releasably grip the probe. A movable stand is provided preferably with a holder for holding the probe. The probe can have a protective cover thereon with a switch assembly mounted onto the probe over the cover.

Radiation detection apparatus

There is provided a radiation detection apparatus having a hand-held radiation detection probe with a switch assembly removably mounted thereon. The switch assembly having first and second switches, one to initiate transmission of electrical signals representing scintillations detected over a set time period to a remotely located control unit for counting and averaging, and the other to direct the control unit to download and preferably record the counted and averaged scintillation values for further use. The switch assembly has an insulating member for electrically insulating the switches from the probe, and spaced gripping members that releasably grip the probe. A movable stand is provided preferably with a holder for holding the probe. The probe can have a protective cover thereon with a switch assembly mounted onto the probe over the cover.

A radiation detection apparatus includes a scintillation counter, a download control device for outputting a scintillation count to a utilization device, and a hand-held probe including a scintillation detector. The apparatus also includes a connector for connecting the probe to the counter, and a switch assembly removably mounted to the probe. The switch assembly has a first trigger for causing the counter to accumulate a first scintillation count over a first period, the counter to accumulate a second scintillation count over a second period, and the detection apparatus to display the second scintillation count. The switch assembly has a second trigger for causing, upon activation, the download control device to manifest an accumulated scintillation count from the counter. A lack of activation of the second trigger during the display of the second scintillation count causes the counter to resume accumulating scintillation counts over the first period.
