If you have ever watched any urban exploring or tourist guide videos from the Chernobyl area you will notice that they always check for radiation and don't go into certain buildings or areas because radioation is not uniform. There's places where there's almost no radiation, then you walk into a random building and the exposure is too high to stay for a longer time. Not sure that's a place you really want to live in, easy to say from a comfortable chair behind a screen somewhere far away.
