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. $50$m deep
• B. $100$m deep below ocean bed
• C. $75$m deep
• D. $500$m deep
• E. $25$m deep below river bed

Answer 1

Answer: (D)

$500$m deep

• Nuclear waste is the radioactive waste material, for example from the use or reprocessing of nuclear fuel.
• Exposure to certain high levels of radiation, such as that from high-level nuclear waste, can even cause death. Radiation exposure can also cause cancer, birth defects, and other abnormalities.
  
• Hence It has been recommended that storage of nuclear waste after sufficient pretreatment should be done in suitably shielded containers buried within rocks about 500m deep to prevent its harmful effects.
• So, the correct answer is '500 m deep'.
