[en] The aim of this paper is to describe a relatively recent international agreement on the vastly debated concepts of: attributing health effects to low-dose radiation exposure situations that have occurred in the past; and, inferring radiation risk to low-dose radiation exposure situations that are planned to occur in the future. An important global consensus has been recently achieved on these fundamental issues at the level of the highest international intergovernmental body, the United Nations. The General Assembly of the United Nations has welcomed with appreciation a scientific report on attributing health effects to radiation exposure and inferring risks that had been prepared by its United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). This paper presents the author's personal views on this extraordinary development.
