CCRI-mission

Mission

To discuss, foster, enable and co-ordinate the development, comparison and promulgation of national measurement standards for ionizing radiation. We aim to enable all users of ionizing radiation to make measurements with confidence at an accuracy that is fit for purpose.

Vision

A world in which the many benefits of ionizing radiation for healthcare and technology can be realized by accurate, scientifically rigorous measurement, confident that the associated risks are constrained.
