Contribution of Radon Flows and Radon Sources to the Radon Concentration in a Dwelling
Radiation Protection Dosimetry, 1992In this paper a model is presented for analysis of the radon concentrations in a compartment in terms of contributions from transport by flows of air between compartments and from radon sources in the compartment. Measurements were made to study the effect of increased natural ventilation of the crawl space.

Microdosimetry of Radon and Radon Daughters
Radiation Protection Dosimetry, 1990Abstract We have developed an analytical method for calculations of slowing down spectra (fluence rate spectra) and lineal energy spectra for radon and its important alpha emitting daughters, 218Po and 214Po. We have also made calculations of microdosimetric parameters and quality factors for radon-related alpha particles.

Geochemistry of Atmospheric Radon and Radon Products [PDF]
Annual Review of Earth and Planetary Sciences, 1977 The following topics are discussed: measurement of the radon-222 flux to the atmosphere; measurement of the lead-210 atmospheric flux; and the mean residence time of aerosols. A total global model is proposed for radon-222 and its daughters.

Radon in workplaces / Radon an Arbeitsplätzen
Kerntechnik, 2000The EU Member States have to implement the new Basic Safety Standards Directive (BSS) by May 2000. The Title VII of the Directive applies in particular to radon in workplaces. The Member States are required to identify workplaces which may be of concern, to set up appropriate means for monitoring radon exposures in the identified workplaces and, as ...

The Lancet, 1991
Radon and its daughter decay products are thought to be the cause of 5% of lung cancer in the UK. This assessment has been made by the National Radiological Protection Board (NRPB) after a national survey of radon levels in homes, when more houses than anticipated were found to have high levels, and after a reappraisal upwards of the effectiveness of ...

Evaluation of the uniformity of concentration of radon in a radon chamber
Applied Radiation and Isotopes, 2016In order to solve the problem that the evaluation results of the uniformity of concentration of radon in a radon chamber via various methods were difficult to compare, according to its statistical properties, a mathematical model was built to analyze the uniformity of concentration of radon; an evaluation method for the overall uniformity of ...

Radon and Radon Daughter Measurements in Solar Buildings
Health Physics, 1983Measurements of radon and radon daughters in 11 buildings in five states, using active or passive solar heating, showed no significant excess in concentrations over the levels measured in buildings with conventional heating systems. Radon levels in two buildings using rock storage in their active solar systems exceeded the U.S.

JAMA: The Journal of the American Medical Association, 1987
To the Editor.— When the foremost determinant of a phenomenon is omitted from consideration, researchers are necessarily perplexed—as revealed in the Aug 7, 1987, issue of JAMA , which was largely devoted to articles on radiation hazards: "One of the strangest things about radon is that its level in any given house is totally unpredictable.

Radon in the Exhaled Air of Patients in Radon Therapy
Radiation Protection Dosimetry, 2017In the Gastein valley, numerous facilities use radon for the treatment of various diseases either by exposure to radon in air or in radon rich thermal water. In this study, six test persons were exposed to radon thermal water in a bathtub and the time-dependent radon activity concentration in the exhaled air was recorded.

Radon permeability and radon exhalation of building materials
Science of The Total Environment, 2001High radon concentrations indoors usually depend on the possibilities of radon penetration from the surrounding soil into the buildings. Radon concentrations in dwellings up to 100 kBq/m3 were found in some special regions (i.e. Schneeberg/Saxony, Umhausen/Tyrol), where the soil shows a high uranium content and additionally, a fast radon transport in ...
