Application of the ICRP's recommendations on exposures resulting from contaminated sites from past industrial, military and nuclear activities

This paper presents the objectives, scope and progress within the ICRP Committee 4 Task Group 98, on the Application of the ICRP's recommendations on exposures resulting from contaminated sites from past industrial, military and nuclear activities. The objective of TG98 is to: describe and clarify the application of ICRP Recommendations (Publication 103) on radiation protection of workers, the public, and the environment to sites contaminated from past industrial, military and nuclear activities, at which residual radioactivity was never subject to radiological control, or was not controlled according to ICRP Recommendations. Sites contaminated from nuclear and radiological accidents are excluded from the scope or TG98. These are covered by the work of ICRP TG 93. Issues identified in the terms of reference include: characterization of sources, exposure pathways, dose distribution, categories of exposure, protection of the environment, and the setting of reference levels for sustainable protection strategies. Stakeholder involvement is to be considered in all steps.
