    • 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.
    • 辐射检测装置包括闪烁计数器,用于将闪烁计数输出到利用装置的下载控制装置,以及包括闪烁检测器的手持探针。 该装置还包括用于将探针连接到计数器的连接器和可移除地安装到探针的开关组件。 开关组件具有用于使计数器在第一周期内累积第一闪烁计数的第一触发器,所述计数器在第二周期内累积第二闪烁计数,并且所述检测装置显示第二闪烁计数。 开关组件具有第二触发器,用于在激活时使得下载控制装置显示来自计数器的累积闪烁计数。 在显示第二次闪烁计数期间缺少第二触发器的激活导致计数器在第一周期内恢复累积闪烁计数。
