I've seen lots of discussion over the years about how we send clear messages across time, for example nuclear waste sites and how we warn 50 generations down the road. This is a corrollary, what substances are the most dangerous over the long term? I assume it's some form of radioactive material , but which is the worst for the longest?
The other day I read this thing about ATOMIC GARDENING And apparently this controlled mutation is the reason we have ruby red grapefruits. So my question is what ELSE is atomic that I didn't know about? Is there anything else using radiation unconventionally or atomic technology in novel places I didn't suspect?
I work in medical imaging research. We just got a new imaging system and I am about to start working with radioactive materials. I need help identifying a good pair of lab shoes. [more inside]
How do we know whether the fish we eat is essentially free of Fukushima radiation? [more inside]
Is it legal for me to purchase a used radium watch? If so, where can I find one? If I had one, how hazardous would I be to the people around me, if at all?
Can you identify what this truck is carrying? A truck towing two trailers, each with 4 cylinders. Marked radioactive. (photo inside) [more inside]
I want to give some trinitite as a Christmas gift. This involves transporting it across state lines. Am I going to run into problems? [more inside]
I'm trying to find a Japanese short film about two guys in a sushi restaurant who try to out-order an older man. There's no dialogue and it was weird and quite funny, finishing with a radioactive wasabi show-down. [more inside]
Who regularly sells 10-18mm tritium spheres (pictured at bottom), and where can I buy them reliably? [more inside]
Where can I get some small quantities of radioactive materials for science fair type projects? [more inside]
I remember reading a true story online about an accidental death in a physics laboratory during the early studies of radioactivity and nuclear physics experiments. I think it involved a clumsy physics student who accidentally dropped a brick of radioactive material onto a stack of these bricks which set off some sort of chain reaction. Can someone find this story online for me?
My friend was just diagnosed with Graves Disease and the doctor decided it was so serious he should immediately get radioactive iodine treatment, and he was given a 16mCi pill today. So, apparently, he is very radioactive right now, and would set off Homeland Security terror alerts in airports if he walked through. [more inside]
Are there any animals that have evolved a use for radioactivity? If so, what ways is it used? If not, why has this not happened? [more inside]
