Board of Directors

The Radiation Safety Institute of Canada is a self-governing organization. Overall authority and responsibility rest with its Board of Directors. The Directors are chosen for their good sense, practiced judgment and broad experience and are elected independently from the business, academic, legal, health care and other communities and from labour, industry and government. The Board of Directors is an independent body. It is also, by policy, a multi-partite body. The Board seeks and maintains representation from the three traditional sectors of industry, government and labour. To this traditional triumvirate is added a fourth group of independent, knowledgeable and experienced people who support the Institute’s mission.
