A Risk-Based Approach to Health Criteria for Radon Indoors - Report on a WHO Initiative
Abstract The World Health Organisation (WHO), Regional Office for Europe, organised a meeting of a working group on indoor air quality in Eilat, Israel, from 28 March to 4 April 1993. The aim was to develop a risk-based approach to health criteria for radon indoors. The group reviewed the latest epidemiological data from occupational and non-occupational radon exposure, animal experiments and dosimetry. The Group issued 14 conclusions and 23 recommendations on radon related risk to health, on risk management and risk communication. In summary, radon was confirmed as a human carcinogen. Indoor radon exposures resulting in individual risk exceeding 10-3 per year are to be considered as severe and risk reduction programmes implemented. Guidance on risk management and communication is offered to national authorities.
