One, trying to seal up all the holes that allow air exchange between under the house and inside the house. This includes walls when there is a gap behind the wall that goes to the crawl, like where sewer vent pipes come up.
Two, puling the air out from under the house before it can diffuse up into the living space. This means an exhaust fan. The problem here is that if you pull too much air out, especially if there are a lot of holes into the living space, that exhaust pulls air out of the living space, which will massively jump your heating or cooling bills up. Mitigation contractors will often lay plastic sheeting down in the crawl and put air intake pipes under it, but then no one can ever work in the crawl again because you'll poke holes in the plastic sheeting by crawling over it and it's now worthless. But sealing the holes between crawl and living space is hard because there are a lot of them and they're often behind cabinets. There's no magic to it.
You probably live in a warm area, where crawlspaces are vented.
Anywhere that winter temperatures drop significantly below freezing, venting the crawlspace enough to get rid of radon would cause your pipes to freeze.
Most areas with significant radon risk freeze during winter. Here's the EPA's US map:
