Chapter 19, Problem 60E

Interpretation Introduction

Interpretation:

The half life of ${}^{235}\text{U}$ is given. The number of alpha particles emitted by $\text{1}\text{.0}\text{mg}$ of this nuclide in $\text{1}\text{.0}\text{minute}$ is to be calculated.

Concept introduction: Decay constant is the quantity that expresses the rate of decrease of number of atoms of a radioactive element per second. Half life is defined as the time required for the number of nuclides to reach half of the original value.

To determine: The number of alpha particles emitted by $\text{1}\text{.0}\text{mg}$ of ${}^{235}\text{U}$ nuclide in $\text{1}\text{.0}\text{minute}$ .
