The Soviet ANET-W intracavitary neutron therapy apparatus is charged with 252Cf sources, the total mass of the radionuclide being 2100 micrograms. The radiation exposure of the staff has been studied and the results presented. Possible emergency situations have been analysed, methods of their prevention and liquidation worked out. Induced radioactivity in the patient's body has been estimated. Radiation dose levels for the medical staff are 10-15 times lower for the ANET-W apparatus than those for 252Cf sources administered by the manual series system but 10 times higher than those for the AGAT-W gamma-apparatus. The design, blocking system and emergency reset of the sources provide for safe work on the ANET-W apparatus. During liquidation of an emergency situation irradiation of the staff does not exceed 0.3 of the annual maximum tolerance dose. The level of induced activity in the patient's body is insignificant as in 10.5 min it does not exceed background values.
苏联的ANET-W腔内中子治疗设备装填有252Cf源，放射性核素的总质量为2100微克。对工作人员的辐射暴露情况进行了研究并给出了结果。分析了可能出现的紧急情况，制定了预防和消除这些情况的方法。估算了患者体内的感生放射性。ANET-W设备的医护人员辐射剂量水平比手动系列系统施用252Cf源时低10至15倍，但比AGAT-W伽马设备高10倍。源的设计、阻挡系统和紧急复位确保了ANET-W设备的安全运行。在消除紧急情况期间，工作人员所受照射不超过年度最大耐受剂量的0.3。患者体内的感生活度水平微不足道，因为在10.5分钟内其不超过本底值。
