Telah dilakukan pengukuran konsentrasi gas radon (222Rn) dan thoron (220Rn) menggunakan metode pasif CR-39 pada rumah penduduk di Nagari Alam Pauh Duo, Kabupaten Solok Selatan. Pengukuran bertujuan untuk mengetahui dosis efektif yang diterima oleh daerah tersebut. 50 buah detektor dipasang 3 lokasi selama bulan. Hasil terkecil yaitu 7 ± 0,50 Bq/m3 sampai dengan terbesar 37 2,65 rata-rata 14 0,9...

Regional lung deposition for radon progeny (size range, 1 nm to 1000 nm, monodispersed) has been determined employing Gormley-Kennedy, Ingham, Cohen-Asgharian and Yu-Cohen expressions (which describe diffusion deposition), together with Gurman and Cheng formulae for impaction and sedimentation, respectively. The deposition values have been compared with those obtained by using the algebraic exp...

Introduction In this study, effective dose equivalent for the public due to internal exposure to 222 radon ( 222 Rn) was evaluated in three regions of Ramsar, a northern coastal city in Iran. Materials and Methods Measurements were carried out using a radon monitoring device. Outdoor and indoor radon concentrations were measured within 24 hours with an integration interval of 3 hours. Regions w...

Groundwater quality constantly evolves through rock–water interactions, which can enrich groundwater with undesirable elements such as naturally occurring radionuclides. The aim of this study was to understand the cause gross alpha activity exceeding screening value 0.1 Bq L−1 measured in groundwater-derived drinking water vicinity a metamorphic outcrop Hungary. As is strongly dependent on prop...
