What will be the blast radius if there is an accident?

They're moving particles around. Not big blobs of the stuff. Any "blast radius" would not extend beyond the container. No-one will be exploding helicopters above the Vatican today.

  What about warp drives?

Each antiproton annihilation releases 0.3 nJ. So for ~100 antiprotons, one would get 30 nJ which is equivalent to 7 picograms of TNT.

  Now, is it safe to eat?

    Probably, but I doubt there'd be much flavour

      well as everyone knows you first have to marinate the antiprotons, as they're mostly eaten for their texture, not taste.

      Might be a little spicy

  That would be enough to neutralize one Amoeba cell

  What's that in dB(modern nukes)?

I'm not an expert but, E=MC², so take the weight what they're moving around, multiply it by the speed of light squared, that's the amount of joules of energy you have, assuming perfect conversion. It doesn't say how much material they moved though. If it was exactly 1 gram and they cancelled each other out perfectly (according to a quora answer, I refuse to trust AI but a random internet commenter is fine lmao), you've got 2 grams of mass converted to energy which is 180 terajoules or about 43 kilotons, which is about equivalent to 3 Hiroshima bombs. Punching that into https://nuclearsecrecy.com/nukemap/ https://nuclearsecrecy.com/nukemap/ gives a blast radius (of window destroying power) of 5.79 kilometers, or just over 100 km² of affected area.

  They’re going to be shipping around much less than a gram. We haven’t generated close to a gram in total across all particle accelerators on earth so far. Producing a gram would cost ~$2.7 quadrillion - https://ket.org/program/physics-girl/why-this-stuff-costs-2700-trillion-per-gram/#:~:text=There's%20a%20factory%20in%20Europe,this%20material%20is%20so%20rare. https://ket.org/program/physics-girl/why-this-stuff-costs-27...

  lol at having 1 gram of antimatter. They are moving around dozens of atoms here. 1 gram of antimatter is off on humanity's capabilities by roughly a dozen orders of magnitude.

Your body is subject to vastly more ionizing radiation every day than you'd receive from this entire batch of antimatter being introduced directly into your body. Check out the fun in an article like https://en.wikipedia.org/wiki/Air_shower_%28physics%29 https://en.wikipedia.org/wiki/Air_shower_%28physics%29 for the sorts of things that go on every day of your life.
