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 mSvh?1 for Bharathiar University, and 5.08 mSvh?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
mSv, 2847.0 mSv, 2978.4 mSv, 3328.8 mSv, and 3547.8 mSv. Importantly, these
measured doses were significantly below the international recommended dose
limit of 50 mSv.
