Spectroscopy of patient scattered X-rays using Ge detectors

One of the main tasks in radiation protection is the reliable determination of risk relevant dose quantities-like organ doses, effective dose or partial body doses-for exposed persons. In cases, when a more detailed description of an exposure situation is demanded, the radiation field has to be analyzed with regard to the type of radiation, the spectral energy distribution and the direction of incidence, to convert personnel dose (or any other measured dose) into a risk relevant dose descriptor. Especially in context with the increasing number of long lasting interventional examinations or treatments in diagnostic radiology this became a pressing problem in the recent past. (author)
