Reducing the inhalation dose from radon decay products

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...

Estimation 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...

Inhalation dose due to radon and its progeny at Pune

The radon and its progeny concentrations are measured near the surface of the earth at the Indian Institute of Tropical Meteorology, Pune, India. In-situ measurements of the meteorological parameters such as temperature and relative humidity are also made simultaneously. The concentrations show maxima in the early morning hours when the turbulence mixing is the minimum; whereas in the afternoon...

Absorbed Dose Assessment from Short-Lived Radionuclides of Radon (222Rn) Decay Chain in Lung Tissue: A Monte Carlo Study

Introduction: Internal exposure to radon gas progeny can lead to serious biologic damages to the lung tissue. The aim of this study was to evaluate the absorbed dose by lung tissue due to the exposure from short-lived radioactive products of radon (222Rn) decay using Monte Carlo simulation. Material and Methods: A lung equivalent p...
