摘要:
目的:探讨方便、快捷的屏蔽计算方法用于方舱CT机房的屏蔽设计,使其防护检测结果符合周围剂量当量率要求的国家标准。方法:在不考虑工作负荷情况下,利用周围剂量当量率目标管理值和CT剂量分布曲线进行屏蔽透射因子B的计算,从而快速估算各方向屏蔽体的设计值。根据实际防护检测结果结合机房防护进行防护效果分析。结果:优化了CT设备方舱在不同目标管理值、不同机房布局条件下的快速屏蔽估算方法,在确保施工质量的条件下使其符合《放射诊断放射防护要求》(GBZ 130-2020)对防护的要求。结论:优化的方舱式CT影像设备机房屏蔽计算方法可在不考虑CT工作负荷情况下方便快捷地对各方向屏蔽体进行设计。
Abstract:
Abstract: Objective To discuss a fast and convenient shielding estimation method for CT shelter, making the radiation protection conform to the national standards for peripheral dose equivalent rate. Methods Without regard to work load, the management objective values of peripheral dose equivalent rate and the CT dose distribution curves were used to calculate the shielding transmission factor B, thereby quickly estimating the design value of the shield in every direction. Based on the test results of radiation protection in practice and the protection condition of X-ray room, the protective effect was analyzed. Results The method for the rapid shielding estimation for CT shelters with different management objective values and different layouts was optimized, and the optimized method made CT shelter meet the requirements for radiation protection in "Radiation Diagnostic Radiological Protection Requirements" (GBZ 130-2020) under the guarantee of construction quality. Conclusion The optimized shielding estimation method for CT shelter can realize the rapid design of the shield in every direction, without regard to CT work load.
