Question

How long is radioactive waste from nuclear plants radioactive?

Answer 1

Answer:about 10,000 years b maybe

Explanation:Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years). Plutonium-239 has a half-life of 24,000 years. High-level wastes are hazardous because they produce fatal radiation doses during short periods of direct exposure.

Answer 2

It can stay radioactive from 1,000 to 10,000 years. I honestly don’t know which answer to choose but it’s going to be between those two.
