International Radiation Physics Society
 Promoting the global exchange of scientific knowledge in the interdisciplinary field of radiation physics and its applications

IRPS does not require an entrance fee, only triennial (3-year) membership dues.

Due to IRPS’s exceptionally low-cost dues, there is no one-year dues option (Council decision, October 1996).

Membership periods are aligned with calendar years to simplify annual dues notifications. New members who join before July 1 in a given year will have their membership effective from January 1 of that year. Those who join after July 1 will start their membership on January 1 of the following year.

Current members' dues anniversary date remains fixed to January.

Corporate and Organisational Membership is also available. Click here for more information.

Corporations and organizations are welcome to apply for membership.
