The Introductory Nuclear Lab System is a complete student system designed for high school and college level nuclear science instruction.

The System is built around the ST260 Ratemeter which has a large analog meter for direct reading in both cpm and cps.

The ST260 also has an internal rechargeable battery that allows for up to 8 hours of portable operation. Continuous operation is accommodated with an AC charger (included).

The ST260 can also be operated using a computer (PC) via a USB connection. This allows for data to be collected and displayed on the screen in either analog or digital format. All of the data is stored in a format that can easily be transferred directly to many common spreadsheet programs.

The Introductory Nuclear Lab System also comes with a set of 3 U.S. NRC exempt quantity sources (RSS3 or RSS3UN for international orders): 1- alpha, 1-beta, and 1-gamma emitter. This allows users to study the characteristics of different types of radiation.

  • Operating Modes: Counts, High Voltage
  • 4.5 in analog display: CPS, CPM, and High Voltage
  • Internal, rechargeable battery (up to 8 hrs of operation)
  • GM detector assembly complete with sample holder (six positions, 1 cm separation) and BNC cable (3 ft)
  • 20 piece absorber set: Aluminum, plastic, lead (4.5 to 7367 mg/cm2)
  • Set of 3 radioactive sources: 1 alpha, 1 beta, 1 gamma emitter
  • Experiment Lab Manuals – instructor and student editions
