摘要：
The present invention provides a radioactive microsphere comprising glass having the structure of formula Ca3Si2O7 and yttrium oxide, wherein the sphericity of the radioactive microsphere is 0.71-1, wherein the radioactive microsphere become radioactive after being activated by neutrons to produce radiation simultaneously. The present invention also provides a method for preparing a radioactive microsphere and a radioactive filler composition. The present invention can be used to treat tumor by delivering radioactive microspheres to target tissue and then activating radioactive microspheres by neutrons to produce radiation. The radioactivity of microspheres disappears with time and microspheres are dissolved and absorbed by bone tissue finally.本發明提供一種放射微球，包括以化學式Ca3Si2O7表示之玻璃及包含在該玻璃中之氧化釔，且該放射微球之球形度為0.71至1，其中，該放射微球經中子活化照射後具放射性。本發明復提供一種放射微球之製備方法以及一種放射性填充組成物。本發明透過將放射微球遞送至目標組織進行中子活化產生輻射以治療腫瘤，微球之放射性隨時間消失，最終可經骨組織溶解吸收。
