Question

1. the type of radiation (alpha, beta, or gamma) associated with each of the following:

• a helium nucleus
• a high - speed electron
• a neutron becomes a proton
• high frequency waves
• does not cause transmutation

1. on the picture to the right, draw and/or write the type of radiation that can penetrate each material (paper, aluminum foil, lead).

Explanation:

Alpha particles can be stopped by a sheet of paper. Beta particles can penetrate paper but are stopped by aluminum foil. Gamma rays can penetrate paper and aluminum foil and require a thick layer of lead to be significantly attenuated.

Answer:

Paper: Alpha particles
Aluminum foil: Beta particles
Lead: Gamma rays
