beta gamma radiation

alpha radiation對人可以話幾乎冇咩傷害(食左落肚既除外)

咁而定問題係beta定gamma對人傷害性較高

beta有ionizing power而且可以through in人體

gamma有極強既penetrating power 但就冇左ionizing power

2種都會傷害人既

但相比之下邊種程度高d

    In fact, alpha radiation is more harzard to human.

    The amount of radiation absorbed by a unit mass of a material is measured in dose. Its unit is the gray, J kg−1.

    Alpha raidiation can be easily sealed off, but it does not mean its damage is lesser.

    For the same activity of the radiation, human body absorb more from alpha raidiation the beta and gamma.
