Abstract:
The authors analysed methodological problems concerning the use of film dosimetry in the evaluation of annual doses received by workers exposed to X-radiation. This is mainly related to nonlinearity of the optical density of films dependent on the dose and the photon energy. The set of four filters solved these problems. The evaluation of occupational exposure among workers being in contract with X-radiation sources in 1996 as well as the analysis of data on occupational exposure followed since 1966 are presented.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
