[Determination of the effective dose equivalent in gynecologic radium therapy]

In this study, the authors describe how to determine the effective dose equivalent absorbed by occupationally exposed persons during a gynecologic radium therapy. The observed irradiation conditions of the physician and the medical staff are approximated by a standard geometry, for which conversion factors between the measured personal dose, the effective dose equivalent and different organ doses, respectively, are calculated. The results are job-specific conversion factors between dose to a personal dosimeter and the effective dose equivalent for the occupationally exposed persons involved. According to the individual tasks, these factors are between 0.59 and 1.13.
