Explain why the different penetrating abilities of the types of radioactivity could have implications for the health of those using radiation.

the penetration depth of a radiated particle depends on both its mass and its kinetic energy. The higher the depth of penetration, the more likely it is to cause damage to internal organs and the smaller the depth the less likely it is to do so. It is more likely to harm surface cells such as skin cells or hair cells if its penetration depth is small.
