Studies from a pilot survey in 89 houses in Cyprus show that the arithmetic mean for the housing stock is about 7 Bq m-3 and the annual effective dose equivalent to the population from radon progeny is < 330 microSv y-1. Four houses have values > 30 Bq m-3, corresponding to two standard deviations from the mean value. The highest value recorded was 78 Bq m-3. These results are considerably lower than those of other countries reported in the literature. Radon concentrations in houses is… Expand
Systematic grid-wise radon concentration measurements and first radon map in Cyprus
Abstract A systematic study of the indoor airborne radon concentration in the central part of the Nicosia district was conducted, using high-sensitivity active radon portable detectors of the typeExpand
Indoor radon (222Rn) concentration measurements in Cyprus using high-sensitivity portable detectors.
The airborne (222)Rn concentration in the interior of various Cypriot buildings and dwellings was measured using high-sensitivity radon portable detectors (passive electronic devices of the type RADIM3), and the total annual effective dose equivalent to the Cyprus population was calculated. Expand
Radon levels in Cyprus.
Radon levels in atmospheric and aquatic systems in Cyprus have recently been measured using the radon monitor Alpha Guard and analysis of radon concentrations in water was performed using tap and ground water samples collected from several areas of the island. Expand
Systematic grid-based radon concentration measurements in the urban areas of Cyprus
article i nfo A comprehensive grid-based study of indoor Rn concentration in all accessible urban areas of the Republic of Cyprus, where 67.3% of the population resides, is presented. During theExpand
Indoor radon gas levels in selected homes in the Greater Accra Region of Ghana
The aim of the study is to monitor indoor radon gas levels in dwellings in the Sakumono Estates and its environs in the Greater Accra Region of Ghana in order to assess the risk of exposure to theExpand
Environmental assessment of radon levels in Cyprus
Purpose – Radon is responsible for approximately 50 per cent of public exposure to environmental radiation. The purpose of this paper is to quantitatively assess indoor radon levels in Cyprus.Expand
Study of indoor radon and radon in drinking water in Greece and Cyprus: Implications to exposure and dose
Abstract This paper reports passive and active radon concentrations in indoor air and drinking waters in Cyprus and Greece (Attica, Crete) together with exposure–dose estimations. Passive indoorExpand
Radon Concentrations Measurement in Aljouf, Saudi Arabia Using Active Detecting Method
The values of annual effective doses for radon inhalation by the inhabitants were found to vary in the range of 0.08 - 0.80 mSv/y, which are lower than the value 1 mSV/y recommended by ICRP, 1990. Expand
Radon and its Decay Products in the Main Campus of Qassim University, Saudi Arabia, and its Radiation Hazards
Rn-222 is the most important source of natural radiation and is responsible for approximately half of the received dose from all sources. Most of this dose is from inhalation of the Rn-222 progeny,Expand
Evaluation of annual effective dose from indoor radon concentration in Eastern Province, Dammam, Saudi Arabia
Abstract The aim of this study is to determine the indoor radon concentration and to evaluate the annual effective dose received by the inhabitants in Dammam, Al-Khobar, and compare it with newExpand


A national survey of 222Rn in U.S. homes and correlating factors.
Correlations were found to be much weaker than expected, indicating that geographical variations are the dominating effect on 222Rn levels. Expand
Distribution of airborne radon-222 concentrations in U.S. homes.
Apparently large exposures of the general public to the radioactive decay products of radon-222 present in indoor air have led to systematical appraisal of monitoring data from U.S. single-familyExpand
Field and laboratory tests of etched track detectors for 222Rn: summer-vs-winter variations and tightness effects in Maine houses.
Effects of tightness of homes and of bedrock character on indoor 222Rn concentrations were sought in 70 homes in the state of Maine by means of four 6- to 8-month-long surveys over a 1.5-yr period, implying that surveys of individual homes require a full year of monitoring. Expand
Uranium-lead isotopic ages of plagiogranites from the Troodos ophiolite, Cyprus, and their tectonic significance
Zircon populations from two plagiogranites in the plutonic section of the Troodos ophiolite yield U-Pb dates between 90.3 ±0.7 and 92.4 ±0.7 Ma. Zircons from one of the two samples yield U-Pb datesExpand
Theory of passive measurement of radon daughters and working levels by the nuclear track technique.
A theoretical basis is described for long-term measurement of the activities of the alpha emitters in air by the track-etching technique and a set of absorber foils allows the differing response to alpha particles of different energies to be used to identify the relative abundance and the importance of diffusion to surfaces.

Risks from ionizing radiation
For the public in the United Kingdom — and the United States — natural radon is a far greater radiation hazard than are emissions from nuclear installations.
