新型便携式正电子放射性药物防护装置的设计与研究
A study of designing a novel portable radiological protection device for decreasing occupational exposure from positron imaging agent
摘要
Abstract
Objective:To design a novel portable radiological protection device for decreasing occupational exposure from positron imaging agent in nuclear medicine department, which can be used to take radiopharmaceutical from synthesis hot cell, transport it to the injection room and administrate the tracer to patients. Methods: The device was made of tungsten alloy and consisted of several parts which could be disassembled conveniently. The complete closed protection device could contain 2 ml syringe. An additional unit (box) was made for further protection out of the device. Shielding effect was measured when the syringe in the protection device contained 444 MBq(0.5~2 ml)18F-FDG. Results: Shielding effect was 35 mm Pb in front of the protection device and 10 mm Pb out of the auxiliary protection box. Dose-rate measured at a distance of 30 cm from the front and the rear surface of the device was 1.5μSv/h and 0.4μSv/h. The product design parameter and shield effect were committed to its application in workplace to keep the technician safely from the occupational external exposure. Conclusion: The novel portable radiological protection device could reduce occupational exposure effectively and should be widespread in nuclear medicine department.关键词
