A Study on the Bulk Etch Rate of LR-115 Solid State Nuclear Track Detector using Lithium Hydroxide as an Etching Solution

Among numerous applications of Solid-State Nuclear Track Detector (SSNTD), one important application is estimating radon and thoron concentration in an indoor environment. The primarily used SSNTD for this LR-115. Studying the behaviour these SSNTDs different etching solutions essential. In report, Lithium hydroxide solution was to etch LR-115 SSNTD. study thickness film removed carried out at normality effect on bulk rate. change rate with temperature also put study. From results, it discovered that directly proportional solution. Additionally, can be deduced LiOH has lower values when compared those other alkaline solutions.
