Geiger-Mueller Detectors
GP 25 - NOTE: Substitute GP35 after
January 2012A complete detector assembly utilizing a 25 mm diameter end-windowed GM tube for Alpha, Beta, Gamma detection. The plastic stand includes a sample tray and features 10-slots with 1 cm spacing for performing inverse square law experiments and holding radiation absorbers. The GM probe is readily removed from the stand for safe storage, hand-held applications or replacement.

 Splitter BoxThe SB100 Splitter Box enables the use
of a single connector NaI detector with the UCS30 Universal Computer
Spectrometer. Two MHV connectors accept the NaI
detector Input and the High Voltage Input, respectively. The
BNC Signal Out connector goes to the Input
connector on the back of the UCS30. ORDER: SB100 |
