Assessment of the exposure to and dose from radon decay products in normally occupied homes
Article Abstract:
A study was conducted to analyze the effect of exposure to radon products and effects of radon decay to households and the environment. The analysis showed that smoking does not increase lung dose per unit of radon gas concentration. Howeve, smoking increases risk of exposure to radon gas. Homes that use aerosol products have been observed to have a high risk of exposure to radon. Likewise, homes which actively use appliances and products containing radon face greater risk of exposure.

Dynamic model for assessing 222Rn and progeny exposure from showering with radon-bearing water
Article Abstract:
A dynamic model was developed for the size distribution of the radon progeny activity during showering. The model was used to assess radon exposure during and after showering as influenced by factors such as shower duration, aerosol profile, ventilation rate and bathroom dimensions. A shortened shower duration and improved ventilation effectively reduced the dose rate. Similarly, an exhaust fan and a shorter shower lowered indoor inhalation exposure.

Effects of intraparticle porosity on the radon emanation coefficient
Article Abstract:
The mechanisms of radon emanation processes are investigated by analyzing the effects of intraparticle porosity on the radon emanation coefficient of individual material particles. A model which also considers the effects of recoil release of the radon atoms suggests that recoil release works in parallel with solid and pore diffusion. On the basis of results, it is suggested that these three components determine the size of radon particles.
