BTW Thanix Cannon is possible in theroy. Provided they kept the lower temperature Iron/Uranium separate from the higher temperature tungsten. Combining them only during the firing sequence. Which would be to fast for the iron in any appreciable amount to boil away. Once in the cold vacuum of space it would cool the metals down significantly to reduce the temp to below iron's boil point. And depending on how far away the target is even cool down enough to turn into a solid object.
Just a few additions:
1. Space may be very cold, but it's also a very good insulator since matter will only lose heat through radiation. Any specific calculations on how much heat would be lost however are impossible to do without knowing the mass and shape of the object we're talking about (and very complex math that I can't be bothered to do
)
2. Melting and vapor points would change in vacuum, which further complicates things.
I'm not saying it's impossible, but it would probably be very hard to pull off.
Yet you and your team suffer no ill effects from hauling around that block of highly toxic radioactive material. While a logical reason for this is the fact that it typically releases alpha particles when it decays, that block would get quite warm. Also it does release gamma radiation. We know that not all rounds hit their targets, so just imagine the clean up if you used these on the Citadel, in that Hotel on Noveria, or any of those other nice places.
The Council seems to think the use of polonium is fine. It simply doesn't make any sense.
Yeah, polonium rounds the way they are shown in game don't make any sense. In addition to the contamination issues you already mentioned:
Even severe radiation poisoning takes days to kill, so it wouldn't give your weapon any additional stopping power. Not to mention of course the severe ethical issues with using such ammunition (but nobody seems to care about the geneva conventions anyway).
Polonium ammo would only make sense if it was used as a very specialized weapon by assassins to make sure that the target definetly dies even if the initial hit wasn't fatal.
Given in ME3 you can walk around in a nuclear reactor in your hardsuit, I imagine Alliance-issued combat armor does protect from radiation.
Well it's a fusion reactor, so the only really radioactive parts are the inside walls of the containment chamber. And I don't think you walk around inside of that. (And if so, THAT doesn't make any sense.)
Neutron charge: I was always under the impression that the hot labs are shielded in some fancy way (including the bottom of the elevator that you escape in), so the effects are restricted to them. After all, if you don't make it to the elevator, you are dead.
It doesnt even have to be very fancy. Neutrons are fairly easy to shield and the hot labs seem to be seperated by several meters of solid rock and gravel, that would be enough. I don't see any problem with the neutron cleaning on Noveria except of course that the rachni (and you) wouldnt die immediatly, but that's fine for dramaturgic reasons.
