Inhalation Dose Due to Indoor Radon
The Rn and Rn enter the atmosphere mainly by crossing the air interface of either soil-air or building materials. The existence of relatively high indoor concentration maintains a large Rn, Rn concentration gradient between the materials and open air. The present paper deals with the experimental measurement of Rn, Rn concentrations and the associated inhalation dose rates due to them in the dw...
متن کاملEstimation of the effective dose from radon ingestion and inhalation in drinking water sources of Mashhad, Iran
Background: Radon concentration was measured in 50 drinking water samples in Mashhad - Iran. b The tap water used for drinking and other household usages can increase the indoor radon level. Drinking water samples were collected from various places and supplies of public water used in Mashhad. Then radon concentration has been measured by portable radon gas surveyor SILENA (PRASSI) sy...
متن کاملDose estimation and radon action level problems due to nanosize radon progeny aerosols in underground manganese ore mine.
One of the essential parameters influencing of the dose conversion factor is the ratio of unattached short-lived radon progeny. This may differ from the value identified for indoor conditions when considering special workplaces such as mines. Inevitably, application of the dose conversion factors used in surface workplaces considerably reduces the reliability of dose estimation in the case of m...
متن کاملRadon Exposure Assessment and Relative Effective Dose Estimation to Inhabitants of Puglia Region, South Italy
Indoor radon concentrations were measured in dwellings of the Puglia region in Southern Italy using LR-115 passive detectors. The results show that the radon concentrations varied from 15 ± 2 to 2166 ± 133 Bq/m³ with a geometric mean of 114 Bq/m³ and a geometric standard deviation of 2.3. An analysis on the factors affecting radon concentration such as age of the dwellings, floors, and stories,...
متن کاملEstimation of annual effective dose due to radon and thoron concentrations in mud dwellings of Mrima Hill, Kenya.
This study presents radon and thoron concentration measurements and the corresponding effective dose rates in mud dwellings located in the high background radiation area of Mrima Hill, Kenya. Discriminative technique was used for simultaneous measurement of radon and thoron. The effective dose was evaluated based on the concentration of the isotopes and the time spent indoors. Radon concentrati...
