Question

It has been recommended that storage of nuclear waste after sufficient pretreatment should be done in suitably shielded containers buried within rocks about

• A. 500 m deep
• B. 500 feet deep
  
• C. 50 m deep
• D. 100 m deep below ocean bed
  

Answer 1

The correct option is A 500 m deep

Hazards of nuclear waste
Nuclear waste from nuclear power plants, if not discarded properly can cause long term disastrous effects like mutations in many generations of humans. Low doses of radioactivity can cause cancer. Therefore, it is important to have a suitable system in place to dispose of such wastes.

Storage of nuclear waste
After suitable pretreatment of the nuclear waste like packaging it in suitable containers, they are buried at a depth of 500m deep in the Earth's surface at designated sites. This is done to prevent leakage and subsequent exposure of the radioactive material.

Final answer
(D) 500 m deep
