Like any other threat: 1. Determine threat model 2. Model personal risk 3. Rank interventions Some simple ones might be just having a good communication plan with your family, or keeping some extra food and water on hand. If you are near an incident, your desired course of action is to evac as soon as possible outside the fallout area. That likely means conveyance and go bags. You don't need to "bug out" to the woods, but you need some food, documents, medications and other essentials in case you need to be in a shelter for a while. If you do have to hunker down and are in a fallout zone, you need to limit fallout exposure by sealing your home, and have enough supplies for 14 days or so. Iodide tablets to protect your thyroid would be good. You probably don't want to go full bunker. It's a lot of cost and probably not the right thing unless you are likely to be a direct target - but even then your chances aren't great. High cost low reward basically. Note that if you end up on the cusp of fallout, you are probably going to have a reduced life expectancy even with gear. Not much you can do. Maybe pack basic NBC suits and gas masks but those are prone to not being fitted and need semi-regular replacement.
