ICRP Committee 4 Meeting

November 8-15, 2018 – Abu Dhabi, UAE
ICRP Committee 4 covered the wide range of issues during its 2018 meeting in Abu
Dhabi, hosted by the U.A.E. Federal Authority for Nuclear Regulation. The meeting
was also in conjunction with the 1st UAE Radiation Protection Week, where several
C4 members were involved as speakers.
Existing exposure situations: The report of TG76 on Radiological Protection
from NORM in Industrial Processes has been approved by the MC for publicconsultation. The preparation of the report of TG98 on Exposures Arising fromContaminated Legacy Sites is on-going, including interaction with TG 105 for casestudies (see below).
Environmental protection: The report of TG72 on Radiation Weighting Factors
for Reference Animals and Plants has been approved by the MC for public
consultation. C4 discussed the work of TG105 on Considering the Environment
When Applying the System of Radiological Protection, which aims to propose away for the integration of the protection of humans and non-human species in theICRP system, based on case studies. Discussions included further considerations
on ethical values, stakeholder involvement and practical implementation. Information
about the on-going work of TG99 on Reference Animals and Plants (RAPs)
Monographs was provided. C4 also received an update on TG104 Integrating
Protection of People and the Environment, and discussed in the context ofreflection on the system of protection.
Response to Fukushima: The report of TG93 on Protection in the Event of a
Nuclear Accident updating Publications 109 and 111 will be submitted to a specificconsultation of SLOs and stakeholders early 2019. The issue of business activities
affected by a nuclear accident will be addressed in the report and further
investigated with concerned parties. Committee 4 agreed that it is time to consider areport on other types of emergency situations, including update of ICRP Publication
96, and has formed a Working Party.
Topical applications reports: C4 reviewed the report of TG97 on Surface andNear-Surface Waste Disposal. Substantial progress has been made. Work
continues in coordination with TG93 and TG98. C4 will contribute to an ICRP
initiative on the issue of RP in Space Travels, which is on the agenda of the 2019ICRP Symposium in Adelaide, Australia.

Reflection on the ICRP System: C4 discussed the definitions of some terms thatare important for the interpretation of the ICRP System (e.g. occupational exposure)as part of a project to develop an ICRP Glossary. It was agreed to create a WP on
the concepts of reasonableness and tolerability applicable to all exposure
situations. It was also agreed to launch a reflection on ICRP System as an input for
its future revision.
C3/C4 Task Groups: Together with some C3 members, C4 discussed the launchingof TG109 on Ethics in Radiological Protection in Medicine and TG110 on theApplication of the ICRP System in Veterinary Practices. The mandate of TG110,
initially focused on the protection from public and occupational exposures, has been
extended by the MC to the protection of animals as patients.
Interaction with other Committees: C4 was provided information on the work of
C2 TG79 on Effective Dose, C1 TG91 on DDREF, C1 TG102 on DetrimentCalculation, and the joint ICRP/ICRU work on operational quantities for external
exposure.
