For many people, radon in dwellings is the largest contributor to their lifetime exposure to radiation. Requirement50 of IAEA Safety Standards Series No.GSR Part3, Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards, places a responsibility on governments (i.e.national authorities) to “provide information on levels of radon indoors and the associated health risks and, if appropriate, ... establish and implement an action plan for controlling public exposure due to radon indoors.”Since the publication of GSR Part3 in 2014, the IAEA has received many requests from Member States for advice on and assistance in establishing action plans to control exposure due to radon in dwellings. The first step in deciding whether an action plan is needed to control radon exposure of the public is to obtain information on radon concentrations and their distribution in the national housing stock. This is normally achieved by undertaking one or more radon surveys. As a basis for future decision making, it is important that such surveys be designed and conducted in a manner that is representative and free from bias.The purpose of this Safety Report is to provide States with practical guidance on designing and carrying out representative radon surveys as a basis for decisions regarding action plans to control exposure due to radon in dwellings. Before initiating such surveys, it is good practice to evaluate all available relevant information, as this can help inform decisions on the scope of such surveys and the areas where high radon concentrations are most likely to be found. The results of these surveys can provide a basis for deciding whether a national action plan is needed to control public exposure due to radon indoors.This Safety Report is jointly sponsored by the World Health Organization. The IAEA expresses its appreciation to C.Fitzpatrick (United States of America) for his work on drafting and reviewing the text. The IAEA officers responsible for this publication were T.Colgan and O.German of the Division of Radiation, Transport and Waste Safety
