摘要

The 252Cf neutron brachytherapy devices were designed and manufactured after solving those problems: the shield difficulties for 252Cf neutron; the method and facilities for 252Cf neutron source deliver; the dose calculation and measurement for 252Cf neutron. From 1999-2009, more than twenty 252Cf neutron brachytherapy devices had been installed in China. The Chinese radiation oncologists implemented the 252Cf neutron brachytherapy on more than 5 000 different kinds of cancer patients, including cervix cancer; endometrium cancer and achieved ideal results. For special presentation, they had breakthrough on radical treatment for low lying rectal adenocarcinoma with sphincter preservation and melanoma patients after the modification of 252Cf neutron intracavitary applicator and dose calibration.
