Radiation protection in CT pelvis in Fantoma Rando by thermoluminescent dosimetry

This paper presents results of equivalent dose organ determining to both primary beam and scattered radiation in a computed tomography (CT) procedures. All measurements were carried out to abdomen and critical organ (gonads) area. Selected dosimeters showed a standard deviation of 4.1% below to the reference values established by international guide lines. The equivalent dose in gonads was 14.27 mGy.

► The areas surrounding the study, as is the area of the chest, abdomen and a radiosensitive organ in a study of the pelvis (gonads), we obtained a significant contribution.
► This variation can be attributed to three main factors: the number of cuts, the distance and the density difference.
► Increasing the dose equivalent as critical organ is due to completion of the study of the pelvis associated with having a number of overlapping slices.
