Question

Are there nuclear reactions going on in our bodies?

Answer 1

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.

Answer 2

Answer:

Yes, there is radioactive decay happening

…at about 100 nuclear events per 1 kg of body weight every second.

If you compare this to 1,000 kg of sea water from outside the coast of Japan, you will — in that 1 ton of water — find 1 – 2 events per second, counting only that which comes from Fukushima.

However, that is cheating. Including that which was already in there, from minerals and such, kicks up the count to 12,100 Bq per ton, or 12.1 Bq per kg.
