The TLD glass is a device used in measuring the level of radiation in high energy radiation environment like X or G-ray, UV, etc. in laboratory of radiation physics, polymer industry, food processing and material testing where moderate to high level (104-106 R) energetic radiation is used. The process of preparation of glass consists of two steps (i) preparation of a porous silica glass (ii) sintering of porous glass to a monolithic mass after doping the former with an organo copper compound. The glass prepared is used in powder form of TLD application. The present TLD glass is having a capability of measurement of a wider range of radiation dose (102- 106 R). Compared to conventional TLD material like CaSO4 : Dy, CaSO4, Tm, LiF TLD-600, etc. Gives a stable and consistent response in widely varying environmental condition, repeatedly usable for a larger number of times and it is economical.
