Seasonal variation of exposure radiation dose in ishik university using survey radiation dosimeter

الملخص EN

The radiation dose affects health when it causes changes in the cells of the human body.

The risk of harmful health effects generally increases with the amount of radiation absorbed.

In this work, the annual internal radiation doses have been measured in seven building for Ishik University in Erbil city, using active technique (survey radiation dosimeter) during two seasons- winter and spring.

The highest average values of exposure radiation dose were found in dentistry faculties for winter season (0.699 ± 0.09 μSv/h) and lowest values were found in Student dormitory (boys) for summer season (0.109± 0.05 μSv/h).

The highest average exposure radiation dose was found in the basement floor for all buildings compare with the ground, first, second and third floors.

The rate radiation dose in different type rooms depended on the ventilation rate, leakage dose and age of building.

The annual exposure dose was considered as the main factor to assessment risks of that leakage on the health of workers and student.
