Revolt · Accepted Answer

chain reaction

Question 5

Which is a concern about mining for uranium?

Revolt · Accepted Answer

Dust released in the air could be radioactive.

Question 6

How do fission nuclear reactions differ from fusion nuclear reactions?

Revolt · Accepted Answer

Fission reactions are used to generate electricity for consumers, but fusion reactions are not.
