Question

Which of these following methods is the most suitable for the disposal of nuclear waste?

• A. Bury the waste within rocks deep below the Earth’s surface
• B. Shoot the waste into space
• C. Bury the waste under the Antarctic ice-cover
• D. Dump the waste within rocks under deep ocean

Answer 1

The correct option is A

Bury the waste within rocks deep below the Earth’s surface

The correct option is A.

Explanation of correct option:

1. Radioactive wastes are extremely hazardous to the environment as they affect most living organisms. These materials are carcinogenic, which means it has the potential to cause cancer.
2. Hence, it is necessary to dispose of the waste without harming the environment or its inhabitants
3. After proper pre-treatment, it has been suggested that nuclear waste be stored in suitably insulated containers buried beneath the rocks, roughly 500 meters below the earth's surface.

Explanation of incorrect option:

Option B:

1. Shooting the waste into space isn't a good option because its radiation will travel in space without the atmosphere

Option C:

1. We cannot dump nuclear waste on ice covers as its radiation would be so warm resulting in the melting of ice covers.

Option D:

1. In this option, dumping nuclear waste under the deep ocean will give rise to leakage.
2. Because of leakage, there is a risk for marine life in the ocean.
3. Nuclear waste directly attacks organisms' chromosomes.

Final answer: Burying the waste within rocks deep below the Earth’s surface is the most suitable for the disposal of nuclear waste.
