Objective: To analyze the blood picture changes of the ward nurses who nurse the patients received (125)I seeds implantation.
Methods: 32 ward nurses who nurse the patients for (125)I seeds implantation were involved in the experimental group, the control group included 32 ward nurses from the medical oncology never exposed to (125)I seeds. The WBC count, hemoglobin concentration and platelet counts from the two groups were analyzed statistically, respectively. 30 patients received (125)I seeds implantation were selected randomly and γ-ray dose from the unshielded group and lead rubber cloth covering group was detected at a distance of 0, 15, 30, 50, 100 cm from patient body surface and at different angles.
Results: No significant statistical difference was found between the two groups of WBC count, hemoglobin concentration and platelet count (7.1 ± 1.7 vs 6.8 ± 2.0, 132 ± 11 vs 136 ± 11, 236 ± 57 vs 242 ± 61) . The measured radiation dose was close to the natural background dose (10.2-10.8 µSv/h) at a distance of 50 cm from the body surface [ (12.7 ± 4.3) µSv/h] and the same as after 0.125 mm lead equivalent (Pb) rubber cloth shield protection[ (11.2 ± 3.1) µSv/h].
Conclusion: Interstitial (125)I seed implantation is safe on the blood picture of the ward nurses after taking appropriate protective measures.
