Blocking radiation l.jpg

Blocking Radiation

  • Alpha particles are 8,000 times as heavy as beta particles.

  • Paper or clothing will blockalpha particles, while betaparticles require a few sheets of aluminum foil.

  • Gamma radiation is extremely dangerous--a thousand times more potent than xrays.
