scope:

The Commission noted that generally accepted standards for neutron dosimetry did not exist. As a result, the ICRU determined to sponsor an international neutron dosimetry intercomparison which was intended to compare the results obtained by various individuals or groups in performing absolute fast neutron dosimetry. The intercomparison was carried out in 1973 with fourteen groups of scientists participating. Subsequently, the results were analyzed and Report 27 was prepared. In addition to providing an analysis of the intercomparison results, the Report describes the intercomparison procedure, the radiation fields used, the dosimetry systems employed by the participants and important factors in the evaluation of kerma and absorbed dose.
