Due to legally required monitoring and registration of radiation doses received by radiological workers over a specified period of time, dose meters must be worn. Generally, these are TLD or film badges. The TLD-meter is preferred over the film badge as it is read out electronically and can be linked to a data base. Processing film badges is more complicated. The films must first be developed before they can be viewed to quantify and register the radiation dose.
Radiation dose monitoring is carried out by a government-authorised organisation which is responsible for mailing, processing and viewing of the badges. This organisation generates reports, which contain the individual irradiation doses over a specified period of time, as well as the accumulated dose.
