Chapter 8, Problem 59E

Interpretation Introduction

Interpretation:

The type of radiation present outside the cabinet is to be determined.

Concept Introduction:

The penetration power of a substance depends upon the size of the particle as well as the mass of the particle. Because of a relatively large size, alpha particles have low penetration power.

The beta particle has a smaller size than the alpha particle, thus it has a greater penetration power than an alpha particle.

The gamma rays, on the other hand have a very high penetration power.
