Assessment of staff of radiology department annual effective doses during bone scans

Background: The most frequent imaging techniques used by NM departments are skeletal scintigraphy and bone scans. To assess the protective measures and the anticipated radiation hazards, it is crucial to evaluate the patient's doses for the NMC staff. Objectives: Current research intended to evaluate the annual effective doses of radiology department’s staff during bone scans and their health hazards due to radiation. Methods: The study was executed at Nuclear Medical Center, in October 2022 and annual effective dose of radiologists were measured implying the two techniques including 99mTc-MDP TLDs, carrying two dose quantities of Hp (10) and Hp (0.07) and GR-200A TLDs (LiF: Mg, Cu, P). Results: Effective dose of operators was evaluated using 99mTc-MDP TLDs, was found that the mean personal equivalent dosimetry of HP 10 was 0.43 (0.12-0.74) and HP 0.07 was 0.52 (0.11-0.76). Relative strength of residual signal for successive readouts of LiF: Mg, Cu, P chips made had mean GR-200A and Ref. 10 of 0.54+0.23 and 3.10+1.12, respectively. Conclusion: The radiographers in all of the X-ray facilities were well aware of radiation safety and the staff's occupational dosages of HP(0.07) and HP (10) were within the recommended limits.
