Well I was reading up on rays this weekend, and I had an idea. Well there's plenty of ways to generate your own x-rays (which is VERY dangerous, so don't do it), and its commonly known that x-rays are used for pictures. Rays penetrate your hand (or whatever), and continue on to some kind of film that can form a good picture based on intensity of x-rays hitting it, as bone will dampen x-rays to an extent. So the key thing here is, the x-rays go through you (and destroy DNA) yet some is absorbed.
So that got me thinking about gamma rays, those suckers go through just about anything! The sun puts out UV rays, but I assume it emits everything else too (like gamma rays). Now I looked into gamma ray generation, and thats beyond my scope as far as dollars AND safety, so maybe I can use plain ol sunlight. Is there a type of photography film that gamma rays will be absorbed into, and would it have the same effect as trying to take a picture using x-rays?
Just a thought.
