tom swift among the diamond makers

 For science today I had a revelation or whatever you call it recapped everything I learned for this part I was very interested about like the X-rays and radiation and stuff it's kind of cool but very dangerous. Did you know smoke detectors have just a teeny little bit of radiation it was the stuff that you use for other stuff not in like the bombs use uranium and this stuff is less so you need more of it to even come close to making a bomb or something and you can use radiation to get rid of cancer cells but you usually kill some good cells too?
