Question 1

Correct Answer:

Verified

If there were such a thing as a 'single jump' through the radioactive decay chain of something like uranium-238, the emitted particle would consist of many tens of protons and neutrons. This size particle would require more ejection energy than is available in the nucleus of atoms. No such giant emitted particle has ever been observed or theorized to exist.

Question 2

Correct Answer:

Verified

Rock depositories are not guaranteed to be stable for hundreds of thousands of years. Nuclear waste deposit sites can be vulnerable to terrorist attacks. Materials have not been developed to contain waste products with half-lives in billions of years.
