Question

Are there nuclear reactions going on in our bodies?

Answer 1

yes, your body also contains a small amount of radioactive potassium-40. These radioisotopes occur in vanishingly small quantities and we are evolved to deal with their radiation.

Answer 2

Yes!

Step-by-step explanation:

Nuclear reactions do indeed occur in the human body, but the body does not use them. Nuclear reactions can lead to chemical damage, which the body may notice and try to fix.
