(Vinca Inst Nuclear Sci, 2024) Pitchaikannu VENKATRAMAN; C.S. SUREKA; Lalit Mohan AGGARWAL; Sunil CHOUDHARY
Banaras Hindu University and Bharathiar University conducted a study to assess occupational radiation doses among non-medical workers in X-ray diffraction analysis work environments at science departments. A total of five non-medical radiation workers were monitored to determine their average annual effective dose. Thermoluminescent dosimeters were issued to five X-ray diffraction analysis technologist to record their dose for a month. Dose rate measurements were recorded using survey meters. The average monthly dose for workers was 0.35 mSv. Average ambient dose rate values were 0.45 μSvh-1 for Bharathiar University, and 5.08 μSvh-1 for Banaras Hindu University. Conclusions dose levels are below the limits recommended by the International Commission on Radiological Protection. The study found the yearly average effective doses for five technologist workers to be 3197.4 μSv, 2847.0 μSv, 2978.4 μSv, 3328.8 μSv, and 3547.8 μSv. Importantly, these measured doses were significantly below the international recommended dose limit of 50 mSv. © 2024, Vinca Inst Nuclear Sci. All rights reserved.
