His creative work firstly lies in : discovering the j particle according to the infinite and disjunctive dialectical materialism viewpoint, challenging " the quark confined ", and investigating the cosmos profounded mystery, by researching to manufacture " alpha magnetic spectrometer "
他創造性的工作在於:根據物質無限可分的辯證唯物主義哲學觀點,發現j粒子,挑戰「夸克禁閉」 ;研製阿爾法磁譜儀,探索宇宙奧秘。Over 25 isotopes of polonium are known, with atomic masses ranging from 192 to 218. polonium - 210, the predominant isotope of polonium, is radioactive and emits alpha particles on decay
現時已知道釙元素有25個同位素,它們的質量數由192至218 ,釙210是當中顯著的一個同位素,具放射性特徵,會釋出放射性阿爾法粒子。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。
