12.3 Laboratory Radiation Detection Instrumentation
A. Objective To familiarize the trainee with the radionuclide laboratory equipment. B. Assignment The trainer will discuss the location, care, and calibration procedures for equipment found in the radionuclide laboratory. The training exercises include calibration of the instruments defined below. Typical equipment (including single channel and multichannel analyzers) found in the radionuclide laboratory includes the following: - gas-flow proportional counter,
- low background beta counter (Tennelec),
- liquid scintillation counter,
- alpha spectrophotometer,
- gamma spectrophotometer,
- ionization chamber,
- solid state silicon surface barrier detector,
- high purity germanium detector,
- sodium iodide (Tl) detector, and
- x-ray detector.
C. Questions - Describe the theory of operation and its application in the laboratory for the following: a proportional counter, a scintillation counter, and a solid state detector coupled to a multichannel analyzer.
- What is the formula for gamma-ray resolution?
