"I would be curious to know if these systems (especially open looped) increase the risk of radon exposure in the home due to radon gas entering the system?"
The open part of the loop is entirely outside the building structure so there isn't any risk of radon entering the building through the system. Any radon that might be in the ground water would pass through the heat exchanger and be pumped right back into the ground, pond, etc...
