The Commission discussed extensively the report on The Application of the System of Dose Limitation to Natural Radiation. Several items were raised including lack of clarity within the report, length of report being too long, and that extensive revising would be required.
The Commission clarified the conditions stipulated in ICRP-26 regarding requirement to measure dose of workers. The points raised would need to be considered when ICRP-26 comes to be revised.
The Commission received work updates from Committees 1-4 regarding progress on reports. The following decisions were reached by the Commission.
C1 – The Commission approved of the proposed membership of the TG for Developmental effects of irradiation of the embryo and foetus. Discussion regarding publication of C1 work was discussed but no conclusions were reached.
C2 – The Commission agreed to make a positive statement regarding the variance between ALIs and DACs for members of the public to those for workers recommended in ICRP-30.
C3 – The Committee proposed several procedures for editing to the Commission in light of members of C3 unhappy with the current modification of reports sent for final editing. C3 also highlighted the need for the Commission to push for more advertising of reports related to protection in the medical field.
