Disposal of Radioactive Waste

Q. Which of these methods is employed to dispose radioactive waste?

1. All of these
2. Recycling of radioactive isotopes
3. Temporary storage of waste to allow natural decay
4. Geologic disposal underground to reduce radioactivity to natural levels

Q. Assertion: Radioactive wastes are pre-treated and stored in containers 500 m below the earth’s surface

Reason: Nuclear radiation in low doses causes mutations and is lethal in high doses

1. Both assertion and reason are true and the reason is the correct explanation of assertion
2. Both assertion and reason are false
3. Assertion is true but reason is false
4. Both assertion and reason are true but the reason is not the correct explanation of assertion
