Radstorms are a little bit too rare.

[Embolism]

If we reintroduce the radstorm we need to have some kind of protective suits, otherwise it has no point other than to annoy the crewmembers.

It serves to force people into a selected few areas, plus the frantic dash for safe spots: especially for jobs without maintenance access or space explorers: is great.

Really, the radstorm is actually one of the more interesting events, compared to basically everything else except maybe Meteor.
