The Commission agreed that in every meeting, there should be a full discussion regarding financial implications of the proposed program of work.
The Commission agreed to meet in 1981 in conjunction with the ICR and ICRU.
The Commission received progress updates on its Committees and made the following decisions:
C1 – The Commission disbanded the following TGs: Radiosensitivity of the Embryo and Foetus and Influence of Biological Factors on the Risks of Cancer Induction. Suggested revisions to ICRP-26 were given to the Commission’s draft group. C1 proposed the creation of four working groups to begin research on non-stochastic effects, high LET risks, evaluation of radiation risks, and magnitude of risk to embryo and foetus via exposure of mother. These proposals were accepted by the Commission.
C2 – The Commission approved of proposals to disband TG on Radon and Thoron and to establish a TG on Dose to Patients from Radiopharmaceuticals. The proposed change of membership regarding TG on Dose Calculations was accepted. Finally, the Commission expressed that the C2 report completion is of the upmost importance and must be completed as soon as possible.
C3 – Regarding Revision of ICRP-16/17, the Commission emphasised close coordination with C2. Following a question from a personal statement, the various members of the Commission answered that ICRP-26 Paragraph 204 justified Commission’s recommendation concerning doses for persons incapable of providing consent for medical research.
C4 – The Commission approved of proposals to create TGs on Optimisation of Radiation Protection and Practices that Modify Man’s Exposure to Natural Background. The Commission denied the creation of a TG on Protection of the Public in the Event of Radiation Accidents and requested instead that it become a working party. A proposal to call the sum of weighted dose equivalents, the “effective dose equivalent” was approved by the Commission.
Exposure Limits for Radon-222 Etc. – Due to information contrary to what was presented in the report, the Commission postponed recommending exposure limits. The Commission did agree that an appropriate quantity to use was the concentration time integral of potential alpha energy. The proposal to use the term secondary limit and couple with a risk of 50 mSv in a year was approved. The Commission also approved of principle of calculating limit for Rn-220 by relative dosimetric comparison with Rn-222 daughters.
Future work of the Commission was discussed including but not limited to combining stochastic and non-stochastic effects, genetic detriment, index of harm, lifetime risk, and multiple risks.
