Radiological dose estimation due to exposure to attached and unattached fractions of radon and thoron progeny concentrations

The attached and unattached radon and thoron progeny concentrations were measured in indoor environment using LR-115 detector-based Direct Progeny Sensors in a test village at Tehri Garhwal, India. The goal of this study is to determine radiological dosage attributed to inhalation of attached and un...

Zusammenfassung:The attached and unattached radon and thoron progeny concentrations were measured in indoor environment using LR-115 detector-based Direct Progeny Sensors in a test village at Tehri Garhwal, India. The goal of this study is to determine radiological dosage attributed to inhalation of attached and unattached radon/thoron progeny. Human Respiratory Tract Model (HRTM) was used to estimate Inhalation Dose owing to nasal and mouth breathing. The average value of the annual effective dosage due to exposure of radon and thoron progeny was estimated to be 1.4 ± 0.4 mSv/y and 0.6 ± 0.2 mSv/y, respectively. The experimental techniques and results obtained are discussed in detail.
