اندازه گیری میزان رادون آب شرب منطقه قاینات

Background and purpose: 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. Alpha particle emissions as a radon gas decay product can increase the incidence of lung cancer in human. Every person spends ...

بررسی مواد رادیواکتیو سنگین رادون و رادیوم در رودها و آب شرب منطقه رامسر به وسیله دستگاه PRASSI

Inhalation of radon gas 222Rn, which is a decay product of 226Ra, and its decay products accounts for typically about half of the effective doses received by public from all natural sources of ionizing radiation. Radon alpha particles can initiate a series of molecular and cellular events that culminates in the development of lung and other cancers. Also, 226Ra in the environment is widely dis...
