Measuring Radon and Thoron Levels in Sri Lanka

Abstract:

For the first time in Sri Lanka, an attempt was made to measure the outdoor radon levels using CR 39 type passive radon detectors. Preliminary results indicate that in Sri Lanka, ²²⁰Rn isotope is more abundance than ²²²Rn isotope. These results were also confirmed by in-situ measurements. Sri Lanka has one of the highest ²²⁰Rn values in the region. It was also noted that environmental conditions and other physical factors have a significant effect on the outdoor radon measurements using passive discriminative detectors.
