Each radionuclide has a unique half-life. Any electromagnetic or particulate radiation capable of producing ions directly or indirectly in its passage through matter. In general, refers to gamma rays and x-rays, alpha and beta particles, neutrons, protons, high speed electrons and other nuclear particles. LSC Liquid scintillation counter. Monitoring Checking for the presence of sources of radiation under a specific set of conditions.
Monitoring includes measuring levels of radiation fields and determining contamination levels.
Monitoring is performed both for health protection and for protection of current and future research. In the course of employment, education, training or other activities that involved exposure to ionizing radiation. Personnel Dosimetry Devices that measure the cumulative dose of radiation to an individual. Any device capable of producing ionizing radiation when the associated control devices are operated, excluding devices that produce radiation only by use of radioactive materials. A committee consisting of SDSU faculty and staff which sets policy regarding use of radioactive material at SDSU consistent with the radioactive materials license.
