" body gamma knife is mainly used for curing all kinds of body tumors, and the latest generation three - dimensional directional actinotherapy devices. it incorporates many modern high - techs and effectively break through the limit of actinotherapy devices available while precisely focused and three - dimensional directional. it also has adjusted actinotherapy, wide range irradiation and common actinotherapy, and protects the normal organism from damage at best while its dosage precisely destroys tumor organism
「體部伽瑪刀」主要用於治療各種體部腫瘤,是目前世界上最新一代立體定向放療設備,它吸收了眾多現代高新技術成果,有效地突破了現有放射治療設備的局限,兼備精確聚焦立體定位等優點,具有適形調強放療大野照射及普通放療等多種功能,能夠在劑量準確摧毀腫瘤組織的同時,最大程度地保護正常組織免受損傷。3. using the improved pas technique, the relative absorption spectroscopy of three ppharyngeal carcinomas cell ( sune - l, cne - l, cne - 2 ), relative absorption coefficient at the wavelength of 420nm of the three cells exposure to different x light quantity, are measured. the photoacoustic signal from the died cells is studied through dying the cells
用改進的歸一化光聲光譜技術測量了三株人鼻咽癌細胞( sline - 1 , cne - 1 , cne - 2 )的歸一化吸收光譜系數以及這三株細胞在420nm處的吸收光譜系數對x光放射劑量的依賴關系,並用胎盤蘭對細胞染色,用以反映死細胞的光聲信號。The alpha particles released from polonium - 210 have a very low penetrating power and can be stopped easily by the outer layer of skin or a sheet of paper. it is unlikely that the particles can affect human body through direct irradiation. however the ionization power of alpha particles is very high
釙210釋放的阿爾法粒子穿透能力很弱,人類的皮膚或一張紙已能隔阻它,粒子經照射影響人體的機會很微,不過由於它的電離能力很強,如果人類吸入或進食含有釙210的物質,其釋放的阿爾法粒子就能直接破壞內臟細胞,即使所吸收的份量不多,也會損害身體健康,急性高劑量阿爾法輻射可以引致輻射中毒。It will also make a contribution to unification and dissemination of the quantity values of the absorbed dose for electron beams in cnnc ( china national nuclear corporation )
本課題屬于國防科工委放射性計量一級站「九?五」計劃項目,對于核工業系統電子束吸收劑量的量值統一和量值傳遞具有重要意義。How it works : instead of hilling a tumor with large beams of radiation from only a few directions, as is done with conventional radiotherapy, peacock calculates precise angles and dosed using a computer and ct scan
工作原理傳統的放射治療是從幾個方向用大量的放射性光束來攻擊腫瘤,而「孔雀』則是用計算機和ct掃描儀計算出腫瘤的精確角度和輻射吸收劑量。Abstract : as viewed from developing rit, rit are discussed on the following points such as the effective absorbance dosage, selection of administration way, application in clinical experience both abroad and at home , as well as the problems met in clinical application and the solving strageties
文摘:從發展放射免疫治療的必要性出發,著重敘述其治療腫瘤的有效吸收劑量、多種給藥途徑的選擇以及在國內、外臨床實踐中的應用,並簡述其在臨床應用中所面臨的問題及解決策略。Methods : human peripheral blond lymphocyte ( pbl ) proliferation method was used and the population were classified by the length of service, classes of work and cumulated absorb dose
方法:用外周血淋巴細胞細胞培養法對放射工作人員進行微核檢測並按工齡、工種、累積吸收劑量等分類並設立對照組進行微核率的比較。The lethal dose for acute radiation exposure is generally about 4 siverts. one becquecel of polonium - 210 causes a radiation dose of 0. 51 micro sivert 956sv if ingested, and 2. 5 956sv if inhaled. since polonium - 210 has an activity of 1. 66 x 10
在進食或吸入1貝可bq放射性活度的釙210以後,可以分別吸收到0 . 51微希沃特956sv和2 . 5微希沃特956sv輻射劑量,而每克釙210有1 . 66 x 10分享友人
