Title: Indoor Radon Measurement in Van

Abstract

In this study, indoor radon concentrations obtained from the radon surveys conducted in the Van. Radon monitoring was performed by applying a passive, time-integrating measuring technique. For this purpose, CR-39 nuclear track detectors were installed in dwellings for 2 months. After the monitoring period, detectors were collected. In order to make the alpha tracks visible, chemical etching was applied to the exposed detectors. Nuclear track numbers and the corresponding indoor radon concentrations were determined. Annual effective dose equivalents and the risk probabilities caused by indoor radon inhalation were calculated, and the found results compared with the indoor radon concentrations' data measured in different provinces of Turkey.

  • A passive-type radon/thoron detector was used for measuring indoor radon and thoron concentrations at 90 dwellings in Aichi and Gifu prefectures in central Japan during 90 days from December, 2006 to March, 2007. The radon and thoron concentrations were 21.1 Bq/m3 and 25.1 Bq/m3, respectively. The dose due to radon and thoron in dwellings was roughly evaluated as 0.7 mSv/y and 2.4 mSv/y, respectively. The examination of the geological factor and house condition having an effect on indoor radon concentration was performed.
  • A large volume (1500 cm[sup 3]) alpha scintillation cell to measure indoor radon is described. Air is sampled directly into the cell and gross alpha activity is measured after three hours. The cells are suitable for concentrations higher than 10-20 Bq/m[sup 3]. They were successfully used for randon measurements in kindergartens in Nova Gorica. 7 refs., 2 figs., 1 tab.
  • The technical and scientific basis for the measurement of indoor {sup 222}Rn concentration using an E-PERM (Electret passive environmental radon monitor) has been described in our earlier work. The purpose of this paper is to describe further development of a practical and convenient system that can be used routinely for indoor {sup 222}Rn measurement. The ion chamber is now made of electrically conducting plastic to minimize the response from natural gamma radiation. A spring-loaded shutter method is used to cover and uncover the electret from outside the chamber. The electret voltage reader has been modified to improve the accuracy andmore » the ease in operation. The calibration, performance, error analysis, and lower limits of detection for these standardized versions of E-PERMs are also described.« less
  • This study assesses the indoor radon concentrations for the city of Edirne situated in the European part of Turkey (Eastern Thrace). A total of 88 CR-39 nuclear track detectors were kept in basements of the selected apartment buildings and houses for passively determining the indoor radon levels of the dwellings for a period of three months. The detectors were then collected and a chemical process of etching was applied to the films. At this stage, the tracks left by alpha particles on the films exposed to radon gas were visible and were counted with a microscope (500xmagnification) to estimate themore » corresponding indoor radon concentrations. The average indoor radon concentration was found to be 49.2 Bq/m3 equivalent to an annual effective dose of 1.24 mSv. The measurement results obtained in this study show no significant departure from the other parts of the country.« less
  • Radon source and indoor radon concentrations were measured in 240 homes. Waterborne radon concentrations ranged from 0.4 to 360 kBq/m{sup 3}, with a geometric mean value of 8.6 kBq/m{sup 3} (230 pCi/L). Dry soil samples showed an average radon emanation of 16 Bq/kg (0.43 pCi/g) and an average radium content of 26 Bq/kg (0.7 pCi/g). In situ, surface soilborne {sup 214}Bi concentrations ranged from 5 to 50 Bq/kg. Yearly average, indoor airborne radon concentrations ranged from 7 to 3800 Bq/m{sup 3} (0.2 to 103 pCi/L) and varied significantly by season and by compartment. Radon concentrations in living spaces ranged frommore » 7 to 2100 Bq/m{sup 3}, with an average value of 130 Bq/m{sup 3} (3.6 pCi/L) and a geometric mean of 100 Bq/m{sup 3} (2.7 pCi/L). Source and airborne radon concentrations are best described by log-normal distributions. Localized lusters of houses showed significant variation in source and airborne radon concentrations. Regional and geological clusters showed no significant variation in airborne radon, but did evidence some significant variation in source concentrations. Linear regression analysis of airborne radon in below-ground compartments and radon sources indicated significant correlation for emanative radon at individual sites, local clusters, and regional clusters and for {sup 241}Bi concentrations in local clusters.« less
