Incidence characteristics of alpha particles on detectors irradiated in a radon þ progeny atmosphere
نویسندگان
چکیده
The angular and energetic distribution of alpha particles from the Rn chain in air incident on a detector have been determined by the Monte Carlo method. Stopping power of alpha particles in air have been taken from the ICRU49 report. The incident alpha-particle spectrum was found for various equilibrium factors. It has been shown that the spectrum between 5.5 and 7.69 MeV depends on the equilibrium factor. High resolution alpha spectrometry can enable the measurements of concentrations of Po and Po in air. The maximal sensitivity coefficient has also been determined for measurements of Po concentrations. 2002 Elsevier Science B.V. All rights reserved.

Measurement 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...

Radon gases released from the ground surface and building materials are the major sources of ionization in the indoor atmosphere. Radon will undergo radioactive decay in the atmosphere by emitting an alpha particle. The alpha and beta particles, and the gama rays from Rn, Rn and their decay products give up their energy by ionizing the molecules and aerosol particles in the atmosphere. Radon an...
