Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Nuclear reactor waste poses several concerns, including radioactive decay, chemical toxicity, and thermal energy release. Radioactive decay can release harmful radiation, chemical toxicity can contaminate the environment, and thermal energy release can cause fires or explosions.

Multiple choice

How long does it take for nuclear reactor waste to become safe?

  1. Hundreds of years

  2. Thousands of years

  3. Tens of thousands of years

  4. Millions of years
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Nuclear reactor waste can take tens of thousands of years to become safe. This is because the radioactive isotopes in the waste decay very slowly.
