目的确保医用X射线诊断机房屏蔽防护效果符合国家相关标准,从而保护医护人员和公众的安全。方法用国家防护标准理解医用X射线诊断机房屏蔽防护监测结果,分析新旧标准对监测结果进行评价时的不同影响,并对在实际监测工作中遇到的问题进行探讨。结果根据现行国家防护标准对医用X射线诊断机房屏蔽防护效果进行评价更为合理。结论监测实际剂量率和年有效剂量低于国家防护标准规定限值的屏蔽防护是安全的。
Objective To ensure that medical X-ray diagnosis room shield shielding effect in line with relevant national standards, thus protecting the health care workers and the public safety. Methods The national protective standards were used to understand the monitoring results of medical X-ray diagnosis room shielding protection. The different influences of the old and new standards on the evaluation of monitoring results were analyzed. The problems encountered in the actual monitoring were discussed. Results It is more reasonable to evaluate the shielding effectiveness of medical X-ray diagnosis room according to the current national protection standards. Conclusion It is safe to monitor the actual dose rate and the effective annual dose of shield protection below the national protection standards.
