Comparative analysis of radon, thoron and thoron progeny concentration measurements [PDF]
Journal of Radiation Research, 2013 This study examined correlations between radon, thoron and thoron progeny concentrations based on surveys conducted in several different countries. For this purpose, passive detectors developed or modified by the National Institute of Radiological Sciences (NIRS) were used.

Radon and thoron exhalation rate in the soil of Western Haryana, India
Environmental Monitoring & Assessment, 2023 This study reports the exhalation rates of radon and thoron from surface soil collected from 60 rural sites of district Hisar, Haryana, India. The exhalation rates of Rn^222 (radon) and Rn^220 (thoron) were measured by portable SMART RnDuo (AQTEK SYSTEMS)

EXPERIMENTAL TECHNIQUE TO MEASURE THORON GENERATION RATE OF BUILDING MATERIAL SAMPLES USING RAD7 DETECTOR [PDF]
, 2013 Thoron (220Rn) is the second most abundant radon isotope in our living environment. In some dwellings it is present in significant amount which calls for its identification and remediation. Indoor thoron originates mainly from building materials. In this
