“…However, a few studies have found more variability in the trend (Fleischer et al 1983) or a tendency for the winter levels to be lower (Jonsson 1988). Previous studies have consistently found basement levels higher than other floors ( Schmier and Wicke 1985;Fleischer et al 1983;Jonsson 1988).…”

Results are presented from a statewide survey that measured annual 222Rn concentrations in over 2000 single-family, owner-occupied homes in New York state. The participants were selected by a random-digit-dialing telephone interview approach developed by Mitofsky-Waksberg which allows inferences to be made from the sample to the statewide population. After completing a telephone questionnaire and agreeing to have their homes monitored, eligible households were mailed alpha-track detectors with instructions to place one detector in the main living area for 2 mo (during the winter heating season), a second in the main living area for 1 y, and a third in the basement (if applicable) for 1 y. The statewide median concentration for the heating-season, living-area readings was 31.6 Bq m-3, with a median of 24.0 Bq m-3 for the annual living-area readings and 51.8 for the annual basement readings. For the state, approximately 95% of the living-area concentrations and 86% of the basement concentrations were below 148 Bq m-3 (4 pCi L-1). In addition, only 1.4% of the readings in the basement were above 740 Bq m-3 (20 pCi L-1).

“…Results from a survey of about 6000 homes in the Federal Republic of Germany using etched-track 222Rn detectors yield a GM of 40 Bq/m 3 and GSD of 1.8 (Schmeir and Wicke 1985). In spite of the fact that a larger number appeared at higher concentrations than indicated by these Iognormal parameters, only 10 (0.2%) of the homes sampled had concentrations exceeding 500 Bq/m s. O',her results from the FRG indicaZe an equilibrium factor of 0.3 indoors and 0.4 outdoors (Keller and Folkerts 1984).…”

This report is an introduction to the behavior of radon 222 and its decay products in indoor air. This includes review of basic characteristics of radon and its decay products and of features of the indoor environment itself, all of which factors affect behavior in indoor air. The experimental and theoretical evidence on behavior of radon and its decay products is examined, providing a basis for understanding the influence of geological, structural, and meteorological factors on indoor concentrations, as well as the effectiveness of control techniques. We go on to examine three important issues concerning indoor radon. We thus include I) an appraisal of the concentration distribution in homes, 2) an examination of the utility and limitations of popular monitoring techniques and protocols, and 3) an assessment of the key elements of strategies for controlling radon levels in homes.11
