Which of the following is not a practical method of low level radioactive waste disposal ?
Correct answer: B. Filling in steel crates and shooting it off out of earth's gravity
- A. Dilution with inert material
- B. Filling in steel crates and shooting it off out of earth's gravity
- C. Disposing off in rivers & oceans
- D. Discharging to atmosphere through tall stacks after dilution
Explanation
Launching radioactive waste beyond Earth’s gravitational influence is not a practical disposal method because of extreme cost and the danger of launch failure. Dilution, controlled atmospheric discharge, and historically used aquatic disposal are the conventional options cited for low-level waste, subject to regulation.
