摘要

本研究采用手持式检疫仪评估了三角洲州立理工大学12个实验室的室内和室外辐射剂量水平,估算结果显示,平均BIR、平均年等效剂量率(EDR)、平均年吸收剂量率(ADR)、平均年有效剂量当量(AEDE)、平均终生过量致癌风险(ELCR)分别为0.0116 mR/hr、0.9733 mSv/yr、100.69 nGy/hr、0.4940 mSv/yr和1.755。对脏器的剂量显示,在室内和室外,睾丸的剂量最高,肝脏的剂量最低。一般情况下,室内和室外的BIR、ED、AD和AEDE值都小于公共暴露的推荐限值(1msv /yr)。室内和室外的ELCR高于世界允许限值0.29×10-3。研究区室内计算的ELCR为1:29719(约33 / 100万),室外计算的ELCR为1:15 5735(约9 / 100万)。虽然本研究中ELCR的平均值很高,但需要进行进一步的分析和研究来确定教职员工和学生患癌症的风险。

ASSESSMENT OF INDOOR AND OUTDOOR RADIATION DOSE LEVELS IN DELTA STATE POLYTECHNIC, OGWASHI-UKU, DELTA STATE, NIGERIA
This study assessed the indoor and outdoor radiation dose levels of twelve (12) laboratories of Delta State Polytechnic, Ogwashi-Uku using a handheld inspector survey meter and estimation revealed that the average BIR, average annual equivalent dose rate (EDR), average annual absorbed dose rate (ADR), average annual effective dose equivalent (AEDE), average excess lifetime cancer risk (ELCR) is 0.0116 mR/hr, 0.9733 mSv/yr, 100.69 nGy/hr, 0.4940 mSv/yr and 1.755. Dose to organs showed that the testes received the highest dose, while the liver received the lowest dose indoors and outdoors respectively. In general, indoor and outdoor BIR, ED, AD, and AEDE values ​​are less than the recommended limit of unity (1 mSv/yr) for public exposure (ICRP). ELCR for indoor and outdoor is above the world permissible limit of 0.29×10-3. The calculated ELCR in the study area is 1:29719 (about 33 in 1 million) indoors and 1:115735 (9 in 1 million) outdoors. Although the average value for ELCR in this study is high further analysis and studies need to be carried out to ascertain the risk of staff and students to cancer.
