Investigation and Evaluation of Gamma Radiation in Different Places of One University in Jilin City

Objective: Understand annual effective dose equivalent of Gamma Radiation in Different Places of One University of Jilin City, and then make brief analysis and evaluation. Methods: Gamma radiation in different places of one university of Jilin city was monitored with BH3103B portable X-gamma radiation dose rate meter. Results : Gamma annual effective dose equivalent was respectively 0.466,0.227,0.429 and 0.429 mSv in the office building, campus, students' dormitory and bank. Gamma annual effective dose equivalent in hospital under the environment of radiation workers and public is 0.350 mSv. Gamma dose rate of the building environment (office building, dormitory, savings banks) is higher than that of the open environment (campus). They are all below national individual standard to the public (GB 8703-88) (1mSv).
