Özet
To keep the radiation exposure under control is the golden rule for radiation protection. The internal
structure of the human body could be visible thanks to radiology and nuclear medicine for the aim of
diagnosis, and it was possible to destroy tumor cells with external radiation thanks to radiation oncology
for the aim of therapy. Radiation dose monitoring is performed for radiation workers however no dose
follow-up has for students. So, in this study it was aimed to determine the level of radiation exposure
of students who trained in medical imaging techniques program. This work is assessed the radiation
exposure of 132 students during their internships in the department of radiology, nuclear medicine
and oncology with the aid of optically stimulated luminescence (OSL) dosimeters between the years
of 2019-2017. The OSL dosimeters were sent to the RADKOR Personnel Dosimeter Systems Laboratory
(Ankara, Turkey) for measurement. Exposed OSL dosimeters were read according to the laboratory
specific method based on IEC 62387. Equivalent doses are defined as for body Hp(10) and skin Hp(0,07).
Also Hp(10) and Hp(0,07) are defined in the body of each person considered, their values vary from
one person to another and also depend on the location on the body where the dosemeter is worn. For
the students in the roles of trainers, maximum accumulated equivalent doses were found to be 2.07
and 2.14 mSv for body Hp(10) and skin Hp(0.07), respectively. The minimum accumulated equivalent
dose was 0.00 mSv for 112 students both body and skin. The mean Hp(10) and Hp(0,07) for the 1st,
2nd, 3rd and 4th periods were calculated as 0.23±0.38mSv and 0.20±0.35mSv, 0.27±0.42mSv and
0.23±0.34mSv, 0.18±0.37mSv and 0.12±0.30mSv, 0.22±0.63mSv and 0.04±0.34mSv, respectively. The results were evaluated with reference to the Radiation Safety Regulation reported by IAEA. According
to the regulation, the effective dose for radiation officers cannot exceed 20 mSv for the whole five
consecutive years, and 50 mSv for any year. The annual equivalent dose limit for hand and foot or skin
is 500 mSv and 150 mSv for the eyepiece. Therefore, it was determined that all absorbed doses found
under the radiation safety regulations. However, it was seen that some students whose absorbed dose
were found a little bit high acted more courageous with the self-confidence.
