RADON AND THORON PROGENY IN DUTCH DWELLINGS.

, 2018
Radon and thoron progenies in Dutch dwellings cause ~400 cases of lung cancer per year. Some 30% of the risk is due to thoron progeny, which demonstrates that the influence of thoron progeny is much larger than previously anticipated.

The complex influence of filtration operation on indoor ²²²Rn (radon) and ²²⁰Rn (thoron) concentration.

, 2012
Since the proximate source of dose to the cells of the bronchial epithelium is caused by the airborne decay products of radon and thoron, it is in some situations more practical to remove the daughter products from the air in the form of filtration with ...

Long-Term Measurements of Radon and Thoron Exhalation Rates from the Ground Using the Vertical Distributions of Their Activity Concentrations

A long-term measurement technique of radon exhalation rate was previously developed using a passive type radon and thoron discriminative monitor and a ventilated type accumulation chamber.

Development of an indoor thoron model.

, 2009
Increased concentrations of thoron and its decay products were recently found in traditional Chinese clay buildings. Conditions which effect such concentrations were examined in a room which has been rebuilt to scale at Helmholtz Zentrum Muenchen, and in

Radon exhalation rate from the latex pillows and its potential exposure to users

Objective: To develop a new system to accurately measure the radon exhalation from the latex pillows, and to estimate its potential exposure to users. Methods: The new system is composed of two loops, the first loop is designed to trap background radon ...
