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...
متن کاملDependences in Ground Atmosphere Radon, Thoron and Their Decay Products Dynamics
Ground atmosphere is characterized by low activity of radioactive gases and aerosols, which leads to some difficulties in the choice of control methods. Modeling techniques in these cases have undeniable advantages for determining the volumetric activity (VA) of radioactive gases and aerosols in the ground atmosphere. It is known that the activity of radon isotopes and aerosols decay products i...
متن کاملA study on radon and thoron progeny levels in dwellings in South India
Background: Decay products of radon and thoron present in indoor environment are the most important sources of radiation from natural sources which affect human beings, since general public spend at lest 80% of their time in indoor. Materials and Methods: Air samples were collected for measuring the concentration of radon and thoron daughter products from various indoor environments d...
متن کاملاندازه گیری و مقایسه غلظت پرتوزایی رادن در ساختمان های با نمای داخلی از سنگ گرانیت و کربناتی
Based on the last presented reports of UNSCEAR, inhalation of radon gas and its short-lived decay products is a major contributor to the human exposure from natural radioactivity. Lung cancer is the known effect on human health from exposure to radon in air. Radon is found in outdoor air of buildings of all kinds. The main important isotope of radon is 222Rn. Radon (222Rn) is a noble gas...
متن کاملResidence time of tropospheric aerosols in association with radioactive nuclides.
The residence time of atmospheric aerosol particles is a function of various removal processes, such as dry deposition by impaction, diffusion, sedimentation and resuspension as well as wet deposition by rain drops (precipitation scavenging). Estimation of the mean-residence time of atmospheric aerosols could be based on measurements of the activities and ratios of activities of cosmic-ray prod...
