Chapter 16, Problem 7RQ

To determine

Whether the coal-fired power plants or nuclear power plants produces more radioactivity in the atmosphere.

Answer to Problem 7RQ

The coal-fired power plant produces more radioactivity in the atmosphere.

Explanation of Solution

In the atmosphere, about more than 20% of radiation comes from the source that does not belong to nature, such as medical procedures, medical devices, nuclear testing, nuclear power plants and coal industries.

The coal-fired power plants radiate more radiation as compared to nuclear power plants. It is noticed that the coal industries release more than $12000\text{tons}$ of radioactive elements each year. In this, the uranium and thorium are the main constitutes of radiation and are found naturally in coal deposits.

On the other hand, nuclear power plants also produced more than $13000\text{tons}$ of radioactive waste annually, but its radioactive waste does not release directly into the atmosphere. So the coal-fired power plants radiate more radiation into the environment.

Conclusion:

Therefore, the coal-fired power plant produces more radioactivity in the atmosphere.
