Radon risk management: the future challenge for the nuclear community

The short-lived decay products ŽRn-d. of radon gas Ž222Rn, 220Rn. have been identified as a health hazard in occupational exposure situations, as well as a public health risk in general. Decisions will have to be made concerning the initiation and scale of national Rn-mitigation programmes. In view of the potentially significant socio economic impact of such programmes, it is recommended to proceed from the current approach based on Rn-d risk assessment to the integrated approach of radon risk management ŽRRM.. A seven-step RRM is proposed, ranging from the selection of an action level based on an incremental risk-reduction, to the conduct of auditing procedures, monitoring the RRM-outreach factor.
