Abstract

• This work investigated the interaction of LR-115 type II Solid State Nuclear Track Detectors (SSNTDs) with various radiations (neutron, alpha, and gamma). After irradiation, the tracks formed were etched with alkaline solution 10 % NaOH at 60 °C for 90 min. The etched tracks in irradiated LR-115 type II were observed by using an optical microscope. In this study, radon exploration in different environmental samples such as coal, bottom ash, volcanic ash, mud volcano, Crown cement, and tobacco were carried out by using an LR-115 type II (an alpha sensitive plastic track detector). It indicates radon’s existence as an alpha emitter in all different environmental samples. Among them, the radon concentration in the volcanic ash sample was found to be the highest value (105.5511 Bq/m3 ) and exceed the national reference level (100 Bq/m3 ) whereas in the coal sample, was found to be the second-highest value (100.6902 Bq/m3 ).
