Christopher Clement is the Scientific Secretary and Chief Executive Officer of the International Commission on Radiological Protection (ICRP). He became Scientific Secretary in 2008, the ninth to hold this position since ICRP (originally named the International X-Ray and Radium Protection Committee) was established in 1928. He oversees the daily business of ICRP, represents the organisation in many international fora, and has presented well over 300 invited lectures on radiological protection in more than 40 countries. He has overseen the production of more than 70 issues of Annals of the ICRP as Editor-in-Chief, the basis of radiological protection standards, legislation, and practice world-wide. In addition to his ICRP duties, since 2012 he has been a member of the International Radiation Protection Association (IRPA) Executive Council, serving as Vice-President since 2021.

Mr Clement has a Master of Science degree in Medical Physics and is a Certified Health Physicist. He has more than thirty years of experience in radiological protection. Prior to joining ICRP he worked in environmental monitoring and remediation, radiological counterterrorism, and as Director of Radiation Protection at the Canadian Nuclear Safety Commission overseeing radiation protection regulation in all sectors across the country. For several years he represented Canada at the IAEA Radiation Safety Standards Committee and the OECD Nuclear Energy Agency’s Committee on Radiation Protection and Public Health.

He received the two highest honours of the Canadian Radiation Protection Association (CRPA): the Distinguished Achievement Award in 2011, and the Richard V. Osborne Founders' Award in 2015. In 2019, he received the Ambassador’s Award from the Ambassador of Japan to Canada for his work in recovery after the Fukushima Daiichi accident and the promotion of mutual understanding and friendly relations between Japan and Canada. In 2022, he had the honour of being named as a G. William Morgan Lecturer by the US Health Physics Society, and in 2024 was invited to give the Dunster Lecture by the UK Society for Radiological Protection.
