Chris Clement
Scientific Secretary at International Commission on Radiological Protection


Mr. Clement graduated from McMaster University with a Master of Science degree in health physics, and is a Certified Health Physicist (CHP). He worked for a about decade with the Low-Level Radioactive Waste Management Office (part of Atomic Energy of Canada Limited), a federal agency responsible for low-level radioactive waste management in Canada. He then worked for close to a decade with the Canadian Nuclear Safety Commission (CNSC), Canada’s federal nuclear regulator. He held a number of posts at the CNSC, culminating in Director of the Radiation Protection Division, the CNSC centre of excellence for radiation protection, supporting all areas of the CNSC mandate. During that time, Mr. Clement was also co-chair of the Canadian national Federal/Provincial/Territorial Radiation Protection Committee, was the Canadian representative to the International Atomic Energy Agency’s Radiation Safety Standards Committee, and also represented Canada at the Organization for Economic Cooperation and Development Nuclear Energy Agency’s Committee on Radiation Protection in Public Health.

In 2008 Mr. Clement left Canadian federal service to take on the position of Scientific Secretary of the International Commission on Radiological Protection (ICRP). ICRP is an independent Registered Charity established to advance for the public benefit the science of radiological protection, in particular by providing recommendations and guidance on all aspects of protection against ionising radiation. The recommendations of ICRP form the foundations of radiological protection programmes and regulation worldwide. As ICRP Scientific Secretary Mr. Clement:

  •  is responsible for the overall management of ICRP similar to an Executive Director or Chief Executive Officer (whereas the ICRP Main Commission is the ICRP governing board presided over by the ICRP Chair);

  • often represents ICRP in international fora; and,
  • is one of two full-time paid positions within ICRP, the other being the Executive
