Their best-known applications are dating of archeological and geological samples [1], personal, environmental and medical dosimetry [2], CTV screen phosphors, scintillators, X-ray storage, screen intensifying phosphors, laser materials etc [3][4][5][6]. There are a number of commercially available thermoluminescent dosimeters (TLD); the most popular being, LiF:Mg,Ti (TLD-100); CaSO 4 :Dy (TLD-900); LiF:Mg,Cu,P (TLD-700H); CaF 2 :Dy (TLD-200) and Al 2 O 3 (TLD-500) [7].…”
