Chapter 25, Problem 78A

Interpretation Introduction

Interpretation:

It is to be explained why radioisotopes of $\text{C, N and O}$ harmful to living creatures.

Concept introduction:

The process of radioactive decay is how an unstable atomic nucleus loses energy through radiation. A substance that has unstable nuclei is regarded as radioactive.

Answer to Problem 78A

Radioactive isotopes of $\text{C,N and O}$ can be integrated into body tissues.

Explanation of Solution

  $\text{C,N and O}$ are building blocks that makeup body tissues, therefore, radioactive isotopes of these can be integrated into body tissues, causing harmful damage during radioactive decay.

Conclusion

• Bodily tissues are made of basic blocks $\text{C,N\&O}$ .
• Radioactive isotopes of these elements can be incorporated into body cells and cause detrimental damage through radioactive decay.
