An Investigation on Radiation Protection and Shielding Properties of 16 Slice Computed Tomography (CT) Facilities

Abstract

One of the fundamental principles of radiation protection is distance factor. In CT facilities maximum dose occurs near gantry and dose rate is decreases by distance. To know the rate of reduction of the amount of dose that distance is very important for radiation protection procedure especially for apply criterias of International Commission on Radiological Protection (ICRP) on radiation protection. This technical study aimed to investigate the backscattered dose amount from 16 Slice CT devices for verification of radiation protection measures in several CT facilities and also to evaluate the shielding properties of walls of operating room and patient waiting room. This technical study has been performed in Goztepe In this study, we measured the dose rates from the gantry until exit door and behind the door. The results showed that, backscattered dose amount has been decreased by distance. We obtained only background radiation in radiographer room and patient waiting room. The results showed also that radiation protection requirements are maximized in investigated hospitals. It can be concluded that, recent method can be applied for various CT facilities for optimum radiation protection studies which also in discussion with ICRP and IAEA for better radiation protection and shielding in radiology clinics.

Determination of the Radiation Dose Level in Different Slice Computerized Tomography

“…In another study in 2018, the radiation dose rate at a distance of 20 cm from the gantry was found to be 48.5 mSv / h [19]. In both studies, the radiation dose rate at different distances from the gantry was measured.…”

Examining the HAP+ Fe2O3 Response in the Magnetic Field, Radiation Protection and Mechanical Properties

“…Thus besides other code it has been in a variety of studies in radiation fields [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]. In the present study, the FLUKA Monte Carlo Code is utilized to calculate the radiation shielding capacity of the HAP+ Fe2O3 samples [18,[40][41].…”

Bilgisayarlı Tomografi Çekimlerinde Hastanın Yakın Çevresinde Radyasyon Dozu Ölçümleri

“…BT [11]. 2018 yılında yapılan bir başka çalışmada, gantriden 20 cm uzaklıktaki radyasyon doz hızı ise 48.5 mSv/h olarak bulunmuştur [12]. Her iki çalışmada da, gantriden farklı uzaklıklardaki radyasyon doz hızları ölçülmüştür.…”
