NASA tends to overprice everything though. If you give the task to a non-government company or institution they could probably take a single zero off its end.
Nevertheless, the technology to store a gram of antimatter probably isn't even here yet. :)
1. Gamma rays are photons. They are not radioactive in themselves. They move at the speed of light, meaning they will pass through "any" region in miniscule time.
2. Gamma rays are not neutron radiation. They do not make other matter radioactive.
3. Gamma rays do penetrate the skin and cause damage, mostly as radiation sickness rather than burns. Higher-energy photons, such as those generated from annihilation, are less dangerous since they often pass the body unhindered.
Hmm so basically it would be all the effects of an atomic explosion (temperature, pressure, and so on) except for radioactive pollution of the environment... (?)
The A-bomb releases huge amounts of electromagnetic radiation in a very broad spectrum (including gamma and visible light), but they also produce neutron radiation, and it's these high energy neutrons that can interact with and mutate other nuclei into radioactive forms. All this considered, it's mostly the fission products, often extremely radioactive in themselves, that contribute most to the pollution. Compare this to the theoretical
cobalt bomb

You mean the antimatter like in Angels & Demons?
I believe that this is what the discussion's about although it's getting a bit intelligent for me...

JUST ABOUT
followed that!

Are you guys saying that the future of space-travel will be propulsion via anti-matter fuelled vacuum cleaners?

"A couple" isn't even a number and is not specific, but $25 thousand million is both.
25 thousand million?
25,000,000,000?
25 Trillion is the same as a couple of million?
Whatever dude. I wash my hands of you. I probably know more about the subject than you to begin with.Yeah. You're the man.

I like how MyTie degraded to raw trolling. Either that, or he's far dumber than I thought he was.
With comments like:

pot calling the kettle black much?

Listen, my first reply to this whole "grams" thing was an unaccusing logic based analysis. I offered a pretty neutral opinion that wasn't negative at all. You're reply was a terse and angry reply. I then told you there was no need to be defensive, and then you replied with thisI probably know more about the subject than you to begin withTo this, like I said, I wash my hands of you. I'm not insulting. There is no trolling here.
I have yet to say anything to you that you could take offensively. Since there hasn't been any insult, this should be easily dismissed. Can we get on with the topic?

I think antimatter is a possible power supply in the far future, though my understanding of it is thin and basically sums up to "it produces a lot of power when it annihilates, which it does pretty much whenever it feels like".
For the now, nuclear power would be great if people weren't so afraid of it, and for the future stable fusion power. I can't even comprehend the massive energy output we'd have to have to need antimatter to fuel it. It's like trying to visualize a building fifty trillion feet high. Anyways, I'd imagine using such gratuitous amounts of energy can't be good for the planet in general.
On a side note, it's interesting how poorly our brains are equipped to handle thinking of large numbers or amounts of things.
The problem with trying to imagine what we would need that much energy for is you are over imagining how much energy is being produced. If you annihilated a kilogram of antimatter, you would have energy equivalent to 43 megaton of TNT. At 100% efficiency, less two grams of antimatter would fuel Las Vegas for an entire summer week.

I agree with this, here's a fun one: If the nuclear diameter of a Hydrogen atom (1 proton) were the size of a pencil lead (0.5mm), its molecular diameter (the first electron orbit in the Bohr model) would be 75 meters (~246 feet) (meaning the electron would be 37.5 meters (~123 feet) 'away' from the nucleus, by the Bohr model).
You don't need to go to the vacuum of space to find emptiness, most of the space around us is already quite empty =D
