Description At its meeting in Como, Italy, in September of 1987 the Commission approved a proposal by its Committee 1 on Radiation Effects to set
up a Task Group on Risk to evaluate the new estimates of cancer risk, genetic risk and the risk to the fetus that were being developed
by committees such as United Nations Scientific Committee on the effects of Atomic Radiation (UNSCEAR) and U.S. National Academy of Sciences
Committee on the Biological Effects of Ionizing Radiations (BEIR). Eventually as the programme of the Commission evolved in the preparation
of new radiation protection recommendations (ICRP Publication 60, 1991), the work of this Task Group became part of the background on
which Annex B, "Biological Effects of Ionising Radiation" in the new recommendations, was based. In order to provide a complete record
or the biological basis of the recommendations, the preparation of five papers by individual members of the Task Group was agreed upon.
These papers were subsequently reviewed, first by the other members of the Task Group, and then by all the members of Committee 1 of
ICRP. Thus these papers are approved for publication by Committee 1 of ICRP, and are published in the Annals of the ICRP as refereed
papers not specifically adopted by the Commission.
