Bear with me here...

So CERN has been producing a few picos of antimatter for about a dozen years, of which we have maybe trapped a 1/1000000th. So we are nowhere near a reasonably efficient means of using antimatter for energy (or destructive) purposes anytime soon. That said, if we did manage to figure out how to actually create whole antihydrogens and could begin to produce efficient annihilation, what, if any, bio-hazardous radiation would occur. Now, while antimatter is most likely to be one of the most efficient reaction types ever discovered, much like anything we nasty little humans get our hands on, it won't be perfect, so there is bound to be some neutrino radiation. My question is, is neutrino radiation hazardous, and are there other ionizing radiation concerns for antimatter reactions?

Unfortunately, the most definitive (but wholly inadequate) source of information has been volt's beloved wikipedia. It has told me nothing I didn't already know (with the exception of CERN's less-than-stellar production rates). So I'm calling on my homies to assist in this little tidbit of personal-growth research.

Now, easier question. What is the ionizing radiation of a fusion (hydrogen-hydrogen, or better yet, deuterium-tritium) reaction? I know there is gamma and x-ray, but I was of the understanding that it was non-persistent and mostly non-hazardous outside of the range of horrible burning plasma-induced death. Insights?

In its most neutral state, it would produce a ray; specifically Ray, from Ghostbusters.

Don't cross the streams.

"There's something very important I forgot to tell you. Don't cross the streams ... It would be bad ... Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light."

Looks like you have a problem with the interface between the keyboard and the chair.

That's a big Twinkie.

pretty awesome, though the article doesn't go in depth. The idea that we have calculated the total ability of the brain to assimilate information is the most interesting part to me.

Using string theory, we can see that 10^10^16 is actually only 4d, so if you consider all the way to 10d, that's a lot of possible iterations

You would look funny on fire...

Dude, I don't even know what you said. My brain is about to explode just reading that...

You ain't from this planet are you, Vincent? Who is gonna mug two black fellas, holding pistols, sat in a car that is worth less than your shirt?

Question 2: Does anyone remember reading about a method to convert heat energy directly to electrical energy without inducing matter to a plasma state?

I try to take one day at a time, but sometimes you just can't avoid destroying several at once...

Peltier junctions do that:

I'll be sure to blaaaaaagh about that.

Perfect, thanks...

volt is going to kill you though, so for that, I'm sorry

I personally love the concept of beating the shit out of something and getting candy in return... Pure Genius

The problem with our production of antimatter, is that there is a lot more energy which goes into producing it that we could get by using it as a fuel. We're pretty damn inefficient there. Like a ten billion to one levels of inefficient.

is neutrino radiation hazardous

There are billions of neutrinos which pass through you, and the earth every second (65 billion per square centimeter just from the sun according to wikipedia) So none of the three types of neutrinos are not hazardous.
