Radiation Measurement System is built around the Radiation Counter and GM tube along with different types of radioactive sources and absorbers to study the characteristics of radiation, background radiation, Gm’s operation and the interaction of radiation with matter. The radiation counter includes the features of a preset time function, a digital rate-meter with audible beeper and alarm and digitally controlled high voltage supply and computer interfacing via USB cable.

Operation may be as a stand-alone station or directly from the computer when used. Data files are saved in spreadsheet compatible format for importing in most common spreadsheets allowing the student to perform calculations and graph the results for printing.
The Radiation Counter is equipped with upgraded high voltage and an internal pre-amplier allowing operation with optional scintillation detectors for gross gamma counting.
