چکیده

We conducted a lung cancer risk assessment for internal exposure to naturally occurring 222Rn gas both indoor and outdoor. A series of equations were used to estimate Rn concentrations indoor and outdoor and the associated lung cancer risk in some coastal regions in Egypt. The mean 222Rn concentrations were 42.98 (SD 33.12) Bq/m3 and 8.63 (SD 6.16) Bq/m3 indoor and outdoor respectively. The mean risk of radon-induced cancer (deaths per million population) was 83.4 (SD 64.67) indoors and 25.1 (SD19.52) outdoors. Levels were higher for western regions of the country compared to eastern ones but the highest levels were in Rashid (Nile delta). Smoking was shown to increase the risk considerably.

The Monte Carlo Assessment of Photon Organ Doses from 222Rn Progeny in Adult ORNL Phantom

Introduction The potential hazards posed by exposure to radiation from radon have been of great concern worldwide, since it is especially associated with increased risk of lung cancer. Some radioisotopes of radon progeny deposited in the human lungs emit β particles followed by the γ rays. While γ rays are comparatively less damaging to the respiratory system than α and β particles, it is the p...

Introduction: Internal exposure to radon gas progeny can lead to serious biologic damages to the lung tissue. The aim of this study was to evaluate the absorbed dose by lung tissue due to the exposure from short-lived radioactive products of radon (222Rn) decay using Monte Carlo simulation. Material and Methods: A lung equivalent p...
