Chapter 8, Problem 42E
Interpretation Introduction

Interpretation:

The number of gamma rays emitted by Tc-99 in 24 hours is to be determined.

Concept Introduction:

The time required by a radioactive sample to decompose to half of its mass is called its half-life.

In every half-life, the sample is reduced to half of its mass that was taken initially in the current decay.
