Who We Are

The mission of the Council on Ionizing Radiation Measurements and Standards (CIRMS), formed in 1992, is to bring together stakeholders to advance measurement capabilities and standards to support the safe and effective use of ionizing radiation for societal benefit. CIRMS is an independent, non-profit council composed of experts from academia, government, and industry across all areas of ionizing radiation science and technology, providing leadership, focus, and coordinated action on emerging radiation metrology needs.

This mission is achieved through the organization of an annual scientific conference and the publication of a Needs Report which identifies priority areas in ionizing radiation measurements and standards. Developed through expert consensus, the Needs Report serves as a resource for guiding program development and research investment, particularly when resources are constrained.
