CFD Modelling of Radiation Exposure from Inhalation of Radon Decay Products During Showering

Inhalation exposure to haloacetic acids and haloketones during showering.

Inhalation exposure to haloacetic acids (HAAs) and haloketones (HKs) in contaminated drinking water occurs during showering. The size distribution of the aerosols generated by a shower was determined using an eight size-range particle counter, which measured particles from 0.1 to >2 microm. An exponential increase in aerosol numbers was observed while the shower water was on, while the aerosol ...

Exposure of school children to alpha particles

Background: A substantial part of the public’s natural radiation dose is due to the inhalation of radon gas. Most of the exposure occurs indoors where the airborne concentration of radon and its decay products is usually higher than outdoors. Materials and Methods: Radon activity concentration has been measured twice in 50 classrooms in 5 levels (10 each) during summer and winter using solid-st...

  Based on the last presented reports of UNSCEAR, inhalation of radon gas and its short-lived decay products is a major contributor to the human exposure from natural radioactivity. Lung cancer is the known effect on human health from exposure to radon in air. Radon is found in outdoor air of buildings of all kinds. The main important isotope of radon is 222Rn. Radon (222Rn) is a noble gas...

Radon exposure vs. exposure to other sources of ionising radiation.

The purpose of this contribution is to situate the radon issue within the whole field of radiation protection. There is among health physicists a fairly general consensus that exposure to radon decay products constitutes the largest and most variable contribution to the population exposure. It is therefore ironical that precisely this exposure is the subject of constant disputes with regard to ...
