Chapter 8, Problem 3SC

Interpretation Introduction

Interpretation:

The type of particle present in a radioactive sample is to be determined.

Concept Introduction:

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

Beta particles are smaller than alpha particles. Thus, they have a higher penetration power than alpha particles.

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