Description The International Commission on Radiological Protection issued its last basic recommendations in 1977. The recommendations have been used
widely throughout the world to limit exposure of both radiation workers and members of the public to ionising radiations. Supplementary
statements to the 1977 recommendations were issued when necessary by the Commission, but developments in the last few years have made
it necessary to issue a completely new set of recommendations, officially adopted in November 1990. In publishing these recommendations,
the Commission has had three aims in mind: to take account of new biological information and of trends in the setting of safety standards;
to improve the presentation of the recommendations; and to maintain as much stability in the recommendations as is consistent with the
new information. The recommendations are set out in the form of a main text supported by annexes. The main text contains all the recommendations,
together with sufficient explanatory material to make clear the underlying reasoning for policy makers. The supporting annexes contain
more detailed scientific information on specific points for specialists.
Audience
For regulatory and advisory agencies at regional, national and international levels; management bodies with responsibilities for radiological
protection; professional staff used as advisers; and individuals, such as radiologists, who have to make decisions about the use of ionising
radiation.
