Abstract

Computed Tomography scan is a device in hospital which used for giving anatomy of human body images for diagnostic. Usually people use CT – scan for detecting abnormalities in human body such as cancer. CT – scan uses X- ray as the source, so the organ that being examined has a risk of radiation exposure. The purpose of this research is to measure the number of absorbed radiation in order to meet the radiation dose protection requirement for the patients. As a human body, in this research use a Rando Alderson solid humanoid phantom. Then lithium fluoride thermoluminescent dosemeters (TLD) - LiF were placed on the thorax and abdomen part of the phantom for dose measurement. This study using standard protocols for thorax and abdomen scanning. To find the smallest absorbed radiation dose, the radiation dose from three different slice thickness were used and were compared. It can be concluded that the thicker the slice thickness the smaller the radiation dose.
