TLD

The most common types of TLDs are phosphors such as lithium fluoride (LiF), lithium borate (Li2 B4 07 ), calcium sulphate (CaSO4) and calcium fluoride (CaF2 ) doped with impurities called activators

Li based TLD are mainly used for soft tissue equivalent, and Ca based for bone Soft tissue or lung Bone LiF (Mg, Ti)
