title: [The new radiologic units of measurement gray and becqerel (author's transl)].
abstract: The general conference on weights and measures in June 1975 introduced the new names of units, the Gray (for ionizing radiations) and the Becqerel (for activity of a radioactive substance), on an international level. The reasons for this change--the units hitherto valid are the Rad and the Curie--and the international efforts at durability of the new regulations are reported.
