The Ionizing Radiation Standards (IRS) group disseminates, maintains and develops standards for ionizing radiation. It also conducts research and development related to the measurement of ionizing radiation and provides services such as calibrations, irradiations, consultations and training to its client community. Our clients includes organizations and institutions involved with cancer radiotherapy, radiation protection, industrial irradiation and international standards.
Major activities include the development of standards and measurement techniques related to: exposure and air kerma in low- and medium-energy x-ray and 60Co γ-ray beams; absorbed dose to water in 60Co γ-ray beams and in linear accelerator electron and photon beams; neutron fluence and neutron dose equivalent; and absorbed dose to tissue in a β-ray field. Our group is also well known for its contributions to Monte Carlo calculation techniques for the simulation of electron and photon transport, and in particular for distributing the popular EGSnrc code system.
