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.
