Investigating Indoor Radon Concentration Using CR-39 Detector; a Case Study of Gachin Dwellings in Hormozgan
Introduction: Radon is a colorless inert gas which decay products are the main component of natural radioactive elements that are naturally produced in under layers of earth crust by decay of radium and uranium. It enters through buildings via gaps and cracks. Radon gas decay products like alpha particle can increase the incidence of lung cancer in human. Since every person sp...
متن کاملRadon concentration and gamma exposure in some Kosovo underground mines
Background: In this study are submitted the radon concentration measurement results of four underground mines: Stanterg, Artana, Hajvali and Badovc, which are owned by Trepça Enterprise, Kosovo. The mines have the same geological formation and from these mines are extracted ores rich with lead, zinc, silver, and gold. The radiation exposures caused by radon and radon daughters was determ...
متن کاملMeasurements of Indoor Radon Levels in India using Solid~State Nuclear Track Detectors: Need for Standardisation
Solid-state nuclear track detectors are being used to obtain the time integrated concentration levels of indoor radon/thoron and their daughters. This technique is preferred for taking such measurements in dwellings Such measurements are important as the radiation dose to human beings due to indoor radon constitutes more than 50 per cent of the total dose including that received from the natura...
متن کاملRadon Assessment with Solid-state Nuclear Track Detectors in Bucharest and Its Surrounding Region
Radon contributes with more than 50% to the dose equivalent to the public coming from natural sources, and is a major risk factor for lung cancer occurrence (10–14%, in Europe, p.a.) which should be investigated. Insufficient data on radon levels exist for Romania up to now and further extensive surveys are needed. The paper presents a series of in-situ indoor radon data in various locations in...
متن کاملResidential Radon Concentrations in Kathmandu Valley Using Solid State Nuclear Track Detectors
Measurement of radon is very important in dwellings because of its radiological impact on public health. Radon contributes more than half of the total ionizing radiation dose. It is known from the recent surveys in many countries that radon is the second cause of lungs cancer after smoking. In this context, we have measured radon ( 222 Rn) concentration in different dwellings of Kathmandu valle...
