Measurements of thoron exhalation rates from soil and building materials with scintillation cell

, 2004
In the past decades, international data base on radon (Rn-222) has been improved steadily. However, representative data on thoron (Rn-220) are still few.

Radon and thoron inhalation doses in dwellings with earthen architecture: Comparison of measurement methods.

, 2017
The radioactive noble gas radon (222Rn) and its decay products have been considered a health risk in the indoor environment for many years because of their contribution to the radiation dose of the lungs.

Thoron Exhalation Rate Measurement – Findings from a Large Worldwide Intercomparison Study

Radiation Measurements
A global intercomparison study was conducted to measure the thoron (220Rn) exhalation rate from two building materials, with participation from five European laboratories and three Asian laboratories. The test samples—phosphogypsum and unfired clay—were circulated among the laboratories using a sequential proficiency testing scheme. The assigned values

Integrating radon and thoron flux data with gamma radiation mapping in radon-prone areas. The case of volcanic outcrops in a highly-urbanized city (Roma, Italy)

, 2019
An integration of laboratory radon and thoron exhalation data with gamma radiation mapping is applied to assess the geogenic radon and the exposure of people to natural radiation in a highly-urbanized city (Roma, Italy).

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
