<< when matter and anti-matter meet they annihilate each other and create pure radiation >>
<< Yes, but so does a match... Radiation is not the same as radioactive...
You have radiation coming out of your body right now, does that make you deadly?
What it really does it make pure energy, and if done right, heat and blast...
But it shouldn't be radioactive, no reason to be... >>
What?! What does this mean? When you strike a match, you are NOT annihilating matter. The energy released from a match comes from the rearrangement of chemical bonds, but the matter still exists. An anti matter rxn converts the mass into energy, and ceases to exist.
The energy created in a nuclear detonation is released in all forms of energy, from heat to light, in all wavelengths along the spectrum (from radio waves to ultra-high energy (and radioactive) gamma rays.) We have no way of controlling this conversion (at least that i know of ) and I doubt ever will, as it is a chaoic and uncontrolled release. This would presumably be the same for an anti-matter/matter rxn, but the anti-matter aprticles themselves aren't radioactive.
There are many froms of radiation (like IR coming off your body) and some are radioactive (like gamma rays) but even lower energy radiation can still be deadly (like uv or x-rays, that can mutate your DNA) and not all radioactive particles are EM radiation (alpha particles are high E protons ) Im not even sure if this proper use ot the terminology, any nuclear physists here?
Edit: Ok, read a later post, maybe this is not what you meant, but if it is, you have no idea what you're talking about
