Without a fan, there would be no mechanism to actively draw the air and gas from the soil and move them out through the vent. Even in an unvented crawlspace, the EOV will reduce the level of negative pressure between the occupied space and the crawlspace (I sure hope noone is recirculating this air if you're in radon country). Does running HVAC reduce radon? Poor Air Quality Crawlspace installations may be more straightforward unless you've got a really small crawlspace with minimal clearance. A decrease in the mean value of radon and its attached progeny was found when AC was working.
