I'm not so sure about practicality. It's judging how difficult it is to put on and remove armor, which quite frankly, is always supposed to be time consuming, which is why nearly all scifi armor is meant to be removed through high tech machinery.

And I don't think that N7 armor (or any armor in ME for that matter), is meant to protect from radiation due to what I've seen on the N7 Fuel Reactors mission. If it was, there wouldn't have been a need to vent the radioactive gas to proceed.
