About the IRPS



Welcome to the International Radiation Physics Society


The primary objective of the International Radiation Physics Society (IRPS) is to promote the global exchange and integration of scientific information pertaining to the interdisciplinary subject of radiation physics, including the promotion of

  1. theoretical and experimental research in radiation physics,
  2. investigation of physical aspects of interactions of radiations with living systems,
  3. education in radiation physics, and
  4. utilization of radiations for peaceful purposes.

The Constitution of the IRPS defines Radiation Physics as "the branch of science which deals with the physical aspects of interactions of radiations (both electromagnetic and particulate) with matter." It thus differs in emphasis both from atomic and nuclear physics and from radiation biology and medicine, instead focusing on the radiations.

Next International IRMMA Conference: IRRMA-11 Bologna, Italy - IRRMA-11, 23-28 July, 2023.

Next International ICDA Conference: ICDA-4 Valencia, Spain - ICDA-4, 16-20 October, 2023.
