Basements can be pretty creepy, just ask the kids from Stephen King’s IT. But surprisingly there is an even less unsafe basement that you don’t want to find yourself in. It’s at the site of the Chernobyl disaster. As if a ghost town and radiation filled air aren’t creepy enough, the basement is home to the largest mass of corium known to man. It’s called the Elephant’s Foot, and we’ll tell you how it formed and what makes it so incredibly dangerous. You probably know that radiation isn’t good for your health, but we’ll explain the science behind why that is, and let you know what effect those atoms can have on you. So the basement is bad, but surely you can spend a little time in there, right? You might be shocked to learn just how little time you have to escape if you end up in there, and what the consequences will be if you don’t make it out in time.
