Many people still think that the most dangerous thing you can encounter in the exclusion zone is radiation - it's not true. The radiation level exceeds norms only in some "hot spots", and even there just wearing a gas mask protects you from harm.
Anyone interested in urbex knows, that old and unfinished constructions can be easily damaged, and this damage can harm an explorer in the aftermath by collapsing on him, or underneath him. A broken limb, or a severe wound is a positive scenario in the case of such accident.

I took this photo during one of our recent trips in the Jupiter factory. It's not good, but there's a story behind it. I took it a few seconds before the floor I was standing on collapsed. I was very lucky, because I fell few meters down on a concrete floor, just a few centimeters from some metal pieces, almost giving the heart attack to our sound designer who was recording nearby. I didn’t break anything, but I kept on limping for the next 2 weeks.
So guys - please remember, if you’re exploring, you are the only one fully responsible for your safety - always double check your steps, and don’t hesitate to turn back in some places, your health and life depends on it.
