OBJECTIVE To investigate the effect of reducing home ventilation as part of household energy efficiency measures on deaths from radon related lung cancer. DESIGN Modelling study. SETTING England. INTERVENTION Home energy efficiency interventions, motivated in part by targets for reducing greenhouse gases, which entail reduction in uncontrolled ventilation in keeping with good practice gui...
Balanced ventilation with heat recovery has strong effects on radon mitigation and energy saving in residential buildings. This new technology enables improvement of both indoor air quality and energy efficiency without sacrificing either. Reducing radon by means of forced ventilation requires an increase in outdoor supplied air (i.e. ventilation rate), which in turn can increase energy use. En...
Plastic PicoRad detectors with activated charcoal have been used for radon monitoring in local kindergartens and schools in two cities, Kalisz and Ostrów Wielkopolski, in the region of Greater Poland. Detectors were exposed for a standard time of 48 h during the autumn and winter of 2011 in 103 rooms (Kalisz) and 55 rooms (Ostrów Wlkp), respectively. The detectors were calibrated in the certifi...
The motivation for performing indoor radon reduction measurements or mitigation are generally communicated by the commercial radon industry on the basis of identifying and eliminating a potential health hazard. The role of the commercial indoor radon industry is complicated by the different perspectives of the problem that have developed for various interested parties. Interested parties includ...
BACKGROUND Indoor radon has been determined to be the second leading cause of lung cancer after tobacco smoking. There is an increasing need among radiation practitioners to have numerical values of lung cancer risks for men and women, ever-smokers and never-smokers exposed to radon in homes. This study evaluates individual risks for the Canadian population exposed to radon in homes at differen...
A project is underway to map die indoor radon potential for New York State at the township level. Through a detector distribution program the New York State Department of Health has a database of over 36,000 basement screening measurements. The address field for the indoor measurement data is being linked to latitude and longitude coordinates using data files containing coordinate information. ...
The influence of meteorological parameters on indoor radon in selected traditional Kenyan dwellings.
The effects of outdoor temperature, rainfall and wind speed on the indoor radon concentration in four types of traditional hut in Kenya were investigated by performing short-term (about 48 h) measurements with activated charcoal canisters. The concentrations vary widely (30.2-315.4 Bq m(-3)) during the study period, and the overall mean is 170.3 +/- 39.6 Bq m(-3). The indoor radon concentration...
Radon and its decay products are significant natural sources of radiation exposure for the general population, both in the living and working environment. Thus, extensive residential and occupational radon surveys are continuously performed worldwide. In Greece, indoor radon mapping has covered mostly the north-eastern, eastern and southern part of the country (Nikolopoulos et al., 2002, Clouva...
Long-term exposure to radon increases the risk of developing lung cancer. There is considerable public concern about radon exhalation from building materials and the contribution to indoor radon levels. To address this concern, radon exhalation rates were determined for 53 different samples of drywall, tile and granite available on the Canadian market for interior home decoration. The radon exh...
BACKGROUND Several ecologic analyses have shown significant positive associations between mean indoor radon concentrations and risk of leukemia at all ages (acute myeloid leukemia and chronic lymphocytic leukemia) and for children (all leukemia, acute myeloid leukemia, and acute lymphoblastic leukemia [ALL]). As part of an age-matched, case-control study of childhood ALL in the United States, w...
