Back to me again. I'm sorry my radioactive physics game is weak and I had to speculatively look it up. That's a lot of downvotes, yet no one decided to share the math themselves.

I asked my toddler about the radiation and she said "nana" and then with emphasis "nana" once more.

The downvotes are because our two methods of finding an answer are roughly equally likely to returning a reliable answer.

Mine is slightly better for the climate, maybe. That will likely change as she grows up and uses up more resources. I'll ask her to do the math on that one later, she is busy eating a book right now.
