We are asked to match the characteristics with the correct type of radiation:

For alpha radiation:

Composed of an alpha particle (Helium nucleus)

The symbol is 42He

Charge is 2+ 

A common source is Radium-226

Penetrating power is low

Causes most biological damage

Travels at 1/10 the speed of light


For beta radiation: 

Composed of the beta particle (electron)

Symbol is 0-1e

Charge is -1

Mass (amu) is 1/1837
