The mean radon concentrations determined by the passive detectors are based on calibrations using NBS standard radium-226 solutions and also from participation in the OECD (Nuclear Energy Agency)/CEC radon dosimeter intercomparisons (Commission of the European Communities, 1986) held at the U.K. National Radiological Protection Board (NRPB). Recent calibrations of the new LR-115 based detectors, in terms of response to radon concentrations and F factors have been carried out at the NRPB, which assistance is greatly appreciated. For the etching and track counting procedures used the inner LR-115 piece in the detectors has a mean sensitivity of approximately 1.6 tracks cm 2 kBq l m hr l. 

The radon survey of Ireland is being jointly funded by the Commission of the European Communities under Contract BI6.0117.IRL. The assistance given by the NRPB (UK), An Foras Forbartha (AFF) and M.Burke (UCD) is greatly appreciated.

The dose equivalents in Faulkner and Harrison (1988) and Faulkner and Marshall (1993) were absorbed dose in tissue using a dosimeter placed at or near the surface of the body (NRPB, 1980). This dose quantity can be converted to deep dose equivalent [i.e., //p(lO)] by multiplying by a factor of 1.07 (NRPB, 1990). The original dose equivalents have been modified by this factor and converted to i7p(10) in this Report.

There are limits to what is permitted for each user and this is governed by the Health and Safety regulations. The same applies to people working with X-rays. A good set of free wall charts is available from the National Radiological Protection Board (NRPB)1 that summarizes all these processes.
