By means of a conservative dosimetry model, the values of operational radiological criteria for patients released from hospital--residual activity in a body and dose rate near the patient's body--are substantiated based on the effective dose limit of 5 mSv for persons helping the patient or living with him and 1 mSv for other adults and children. Two sets of operative criteria for radionuclides (125)I, (131)I, (153)Sm and (188)Re used in Russia for radionuclide therapy were derived. Release criteria for (125)I well differ from such values in other countries because in this work absorption of (125)I low-energy photon radiation in the patient was taken into account. When a patient having undergone radionuclide therapy crosses the frontier of Russia, high-sensitivity devices for radiation control at the custom can detect the patient. A simplified radiological assessment of the patient was suggested aimed at provision of radiation safety for patient companions in transport.
借助保守剂量测定模型,基于对协助患者或与患者共同生活的人员5毫希沃特的有效剂量限值以及对其他成人和儿童1毫希沃特的有效剂量限值,论证了患者出院时的操作放射学标准值——体内残留活度和患者身体附近的剂量率。得出了俄罗斯用于放射性核素治疗的两组放射性核素(125)I、(131)I、(153)Sm和(188)Re的操作标准。(125)I的释放标准与其他国家的此类值有很大差异,因为在这项工作中考虑了患者对(125)I低能光子辐射的吸收。当接受放射性核素治疗的患者越过俄罗斯边境时,海关的高灵敏度辐射控制设备可以检测到该患者。建议对患者进行简化的放射学评估,以确保运输过程中患者同伴的辐射安全。
