It woud need to be planned heavily and these Colonies would need to dig underground for protections during strong solar flares. Another option will be to use shields around the Colonies. Otherwise the short exposure will lead to traditions sickness which could lead to many complications. The longer exposure however would lead to cancer due to severe damage to tissues.

Also protecting electronics would be much harder. Your ability to do anything except digging during these times will be limited.
