A coincidence counting system for detection of low level activities

Creators

  • 1. St. Joseph Medical Center, Burbank, CA

Description

A system based on coincidence counting for measuring the absolute activity of isotopes in which a gamma ray is emitted by the nucleus following the capture of the orbital electron with a known half-life is described. If the half-life of the excited state is small compared to the resolving time of the coincidence circuit, the absolute activity of the source can be determined. The system consists of two NaI(Th) crystals, a high voltage supply, 2 preamplifiers, 2 amplifiers, two single channel analyzers, one coincident unit, and three sealers
