À la mémoire de Dr Norman Elwood Gentner

With deepest regret, we note the passing of Dr. Norman E. Gentner on January 14, 2021, in Renfrew, Ontario.

A stalwart figure in radiation biology and radiation protection in Canada and internationally, Norm was a member of CRPA, a contributor to the CRPA Bulletin, and a frequent speaker at CRPA conferences.

Norm was born in Saskatchewan. He received his bachelor’s degree in biochemistry in 1963 at the University of Saskatchewan, winning the Copland Prize as Most Distinguished Graduate. He attended graduate school at the University of California, Davis, again distinguishing himself as the recipient of a Regents Scholarship. After successfully completing his doctoral thesis in 1967, he became a post-doctoral fellow at the University of California and at Stanford University School of Medicine.

Returning to Canada, he pursued research on the health effects of ionizing radiation in the Health and Environmental Sciences Division of Atomic Energy of Canada Limited (AECL). From 1989 to 1993, he was the manager of AECL’s Biological Sciences Program and then senior science adviser from 1993 to 2001.

In 1989, Norm became part of the Canadian delegation to the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). In 2001, he accepted the position of scientific secretary of UNSCEAR where he remained until 2005.

In addition to organizing UNSCEAR sessions and drafting UNSCEAR documents, Norm served as an expert for the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO). As part of his duties, he was an observer to the IAEA Radiation Safety Standards Committee, the International Commission on Radiological Protection’s (ICRP’s) Committee 1 (Radiation Effects), and the Organisation for Economic Co-operation and Development’s (OECD’s) Nuclear Energy Agency Committee on Radiation Protection and Public Health.

After 2005, he continued to serve on UNSCEAR as a representative in the Canadian delegation. As a key member of UNSCEAR, he was also the rapporteur for the 53^rd Session in 2005, a vice-chair of the 54^th and 55^th Sessions (2006 and 2007), and the chair of the 56^th and 57^th Sessions (2008 and 2010).

Those of us who had the pleasure of working with Norm knew him as very knowledgeable, well organized, and hard-working. Above all, he was a good friend who loved company, fine dining, good science, single malt scotch, and a good cigar. He was an outstanding Canadian and he will be missed.
