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...
متن کاملInhalation 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...
متن کاملMeasurement of inhalation dose due to radon and its progeny in an oil refinery and its dwellings .
Background: Radon, an invisible, odorless, heaviest (nine times heavier than air) and radioactive gas is an aberration (the only gas in the long decay chain of heavy metal elements). It is ubiquitously present in dwellings and in the environment. Humans receive the greatest radiation dose in their homes. That's where they spend most time - typically 70%, more for small children. Recent worldwid...
متن کاملEstimation 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...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
