That's simple, sell everything and go live deep in a cavern (hope that there isn't any radiation from any radioactive element on the cavern) or a desert island somewhere in the Pacific. Done, no radiation whatsoever except the ones from the space that reach the earth and are emitted by the "star who shines upon us" (and some more I'm totally forgetting).
It makes me remember when the Fukushima Daiichi nuclear disaster happen a lot of people started to be "nuclear engineers" and knowing the right units of measuring radiation and how much is too much, as also buying portable Geiger counters. I sold 20 Geiger counters on eBay back at the day, for 3x more that they cost me.
But as Haenk said and totally right, is not using or being aware of that is the problem, is using the info in a wrong way.
