  • Title: Characteristic and performance of a simple thoron chamber.
    Author: Zhao C, Zhuo W, Chen B, Zhang H.
    Journal: Radiat Prot Dosimetry; 2010 Oct; 141(4):444-7. PubMed ID: 20833676.
    Abstract:
    For calibration and intercomparison experiments, a thoron chamber with an inner volume of 300 l was designed based on a programmable constant temperature and humidity testing device in this work. The commercial lantern mantles enriched with (232)Th were used as the (220)Rn source and the mantles were set in 3×3×3 points of lattice style inside the chamber. Experimental studies showed that (220)Rn concentrations in the chamber could be easily controlled and adjusted from about 0.5 to 80 kBq m(-3) through manual settings of the relative humidity and temperature, and the spatial distribution of (220)Rn in the chamber was fairly homogeneous.
