Gamma radiation is the most dangerous...

• because it releases the strongest energy

• because it emits gamma particles

• since gamma rays might give you superpowers

• ....actually, gamma radiation is not dangerous

Alpha particles can be stopped by...

• a lead apron

• aluminum foil

• a piece of paper

• nothing
