(P1-81) Differences between Radiation Dosages to Which the Radiology Department Staff and the Public were Exposed

Abstract

Introduction

In this study, the mean daily and annual radiation exposure of the radiology department staff, other hospital health staff, and public volunteers was compared at Maresal Cakmak Military Hospital in Erzurum, Turkey.

Methods

The NEB.211 Dose–Rate Meter with a Gaiger–Müller counter was used to measure the amount of radiation. Six radiology department health staff carried the NEB.211 device during seven working hours. At the end of the day, total absorbed dosages were noted. The same measurements were also done for the six health staff of the other departments and six non-hospital volunteers. Seventeen additional hours were noted for the non-hospital volunteers. The mean value of 17 hours of daily measurements (3.31 mSv) was added to the both group's working hours measurements and the total daily radiation amounts were calculated.

Results

There was no statistical difference between each three groups in working hours (p = 0.087), daily and annual equivalent dosages (for both p = 0.099).

Discussion

The radiology department health staff was exposed to radiation under the border of equivalent dosage which is determined by Turkish Automic Energy Authority. Public volunteers were seen as they were exposed the radiation over the determined border of equivalent dosage. Nonetheless, with changes depending on living standards, the physical properties of living spaces and geographical circumstances per capita exposed annual dosage is about 2.4–2.8 mSv throughout the world. There was no significant statistical difference between the amounts of equivalent dosage which were exposed to the radiology department health staff, the other hospital staff and public members.
