WebComparison of the response of various TLDs to cosmic radiation and ion beams: Current results of the HAMLET project WebThermoluminescent dosimeters or TLDs are a common type of personal dosimeter. A TLD consists of a phosphor-containing solid crystal structure. The phosphor in the TLD interacts with the ionizing radiation upon exposure to X-rays. The light emitted from the crystal is proportionate to the radiation exposure and is measured in millirems.

WebTLDs are suitable to be used in different applications. In particular, it can be utilized in environmental monitoring and staff personnel in work areas that involve radiation exposure. Thermoluminescent dosimeters (TLD) are often used instead of the film badge.
