中文拼音 [lèipō]
類釙
英文
eka polonium-
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。
