Solution: Match the characteristics with the correct type of radiation:  alpha, beta, gamma-lowest penetrating power-purely composed of energy-capable of shallow, sunburn-like, skin damage-causes most internal

Solution: Match the characteristics with the correct type of radiation:  alpha, beta, gamma-lowest penetrating power-purely composed of energy-capable of shallow, sunburn-like, skin damage-causes most internal

Problem

Match the characteristics with the correct type of radiation:  alpha, beta, gamma

-lowest penetrating power
-purely composed of energy
-capable of shallow, sunburn-like, skin damage
-causes most internal biological damage
-highest penetrating power
-travels at 9/10 the speed of light
-travels at speed of light
-travels at a 1/10 the speed of light

Solution

Alpha particles: largest of the particles, most damaging to biological cells, has the highest ionizing power, lowest penetrating power, can be stoped by air, clothing or sheet of paper.

Beta particles: smaller than alpha particles, has lower ionizing power therefore not as damaging to biological cells, but more penetrating power and can only be stopped by a sheet of metal or large block of wood.
