    Abstract

    THE RECOGNITION THAT INDOOR ENVIRONMENTS may be potentially important sites of exposure to elevated levels of the decay products of radon has resulted in an increased demand for measurements of radon and radon decay products indoors. Practical methods and instruments for the measurements of radon and radon decay products have been available since the 1950s as a result of the need to assess radiological exposures to radon-222 decay products in the uranium mining industry . The methods developed for measurements in the uranium mining industry still form the basis for most methods used today in nonindustrial indoor environments. However, improvements have been made to the instrumentation, incorporating advanced technology to improve sensitivity and other performance parameters, ease of use, and size. There have been substantial advances in the development of passive sampling devices, which are relatively low cost and easy to use by homeowners and in largescale screening surveys. Research in the area of radon decay product measurements has advanced significantly, resulting in improved understanding of their characteristics and development of improved measurement methods. Advances in radon and radon decay product measurement technology over the last 40 years have resulted in reliable, easy to use, portable, and relatively low-cost methods.
