...Keramatollah Akbari; Robert Oman Purpose This paper aims to investigate the impact of heat recovery ventilators (HRVs) on the energy use and indoor radon in a one family detached house. Heat recovery ventilation systems, because of reducing ventilation loss through recovered exhaust air, can play...

...Maria M. Johnstone; Paul S. Phillips; Antony R. Denman An extensive radon remediation programme in National Health Service properties in Northamptonshire has been conducted since 1992 and has resulted in many buildings with raised levels being identified and remediated. In the autumn of 1997...

...Gavin K. Gillmore; Gillian Pearce; Antony R. Denman A study has been undertaken of radon levels in an abandoned metalliferous mine in South‐West England. Measurements have been taken in Gunnislake Old Adit using a variety of techniques. Radon gas levels of between 30,000Bq m^‐3...

...Malcolm Sperrin; Gavin Gillmore; Tony Denman In caves, radon has been identified as occurring at elevated levels by a number of groups but, with the exception of major show caves, its impact and risk to those who work in the caves has not received adequate attention thus far. This paper details...

...Chris Scivyer; Kim Noonan This paper describes work undertaken by Building Research Establishment Limited (BRE) for the Building Regulations Division of the UK Department of the Environment, Transport and the Regions, as part of a study into radon protective measures used in new dwellings. The aim...

...Daryl W. Dixon Radon is the second largest cause of lung cancer after cigarette smoking and is estimated to be responsible for between about 3 and 5 per cent of UK lung cancer deaths. This risk is larger than many about which people frequently show concern and will often act to reduce. Radon can...

... insight into all aspects of their experiences with radon gas. Two particular aspects of their experience are explored here. Radon testing in the sample was provided free‐of‐charge to the householders. The main reason given for testing was that they were asked by the National Radiological Protection Board...

...Frederick Marley; Paul S. Phillips Mitigation of radon gas and radon progeny in buildings is based largely on reducing the pressure difference between the point of the radiation source and the point of entry to indoor air. The method is adopted in the mitigation of excess radon concentrations...

...Alan Blythe The Chartered Institute of Environmental Health (CIEH) has been campaigning for a more appropriate and sympathetic government approach to radon since 1987. Its professional members, Environmental Health Officers (EHOs), are at the “sharp end” of most initiatives aimed at securing higher...

...Paul S. Phillips; Julia D. Fraser; Antony R. Denman Northamptonshire is classified as a radon affected area, with greater than 1 per cent of houses being above the UK action level of 200Bq/m^–3. New houses, in areas where >10 per cent are above the action level, have to have primary...

...A.R. Denman; Paul S. Phillips Northamptonshire is classified as a radon affected area, with greater than 1 per cent of domestic dwellings being above the UK Action Level of 200Bq m^‐3. Workplace radon is also a health risk in Northamptonshire, with a significant number of premises being...

... ε is the porosity, ratio of pore volume to bulk volume; λ is the decay constant of radon 7.6 × 10^‐3h^‐1, l is the diffusion length of radon in the disc; θ is the radon production rate Bq.m^‐3; C_B is the radon...

...Michael J. Suess Reports on the deliberations of a World Health Organization working group which met in Eilat, Israel, in 1993 to discuss “risk assessment values”, and a unified approach to the control of human exposure to radon, which is known to cause lung cancer in human beings. Summarizes...
