摘要
目的研制一种SPECT检查放射性水污染智能防护系统。方法根据《医院污水处理技术指南》中对放射性废水的处理标准,应用计算机技术和电离辐射传感技术自主研制一种智能化的SPECT放射性水污染防护系统。结果智能防护系统无需人工干预,可实时防护SPECT放射性水污染,排放废水的放射性浓度低于3.7×102Bq/L。结论 SPECT放射性水污染智能防护系统可实现放射性废水排放的智能化、自动化,排放废水的放射性浓度符合国家标准要求。
Objective To develop an intelligent protection system,in order to protect the radioactive water pollution of SPECT.Methods According to the radioactive sewage processing standards of the hospital waste water treatment technology guide,using computer technology and ionizing radiation sensing technology,an intelligent protection system for SPECT radioactive water pollution was self-developed.Results Without manual intervention,the intelligent protection system could real-time protect the radioactive pollution of SPECT.The radioactive concentration of the discharge sewage was below 3.7×102 Bq/L.Conclusion The intelligent protection system for SPECT radioactive pollution ensures the automatic discharge of radioactive sewage,and the radioactive concentration of the discharged sewage conforms to the state standards.
