How can radiation cause burns?

I wouldn't guess it transfers much heat so why does it cause skin "burns"?

Others have responded in complex terms, but here is a very simple one.

Radiation kills cells by destroying their DNA. The body reacts as best it can. The results look like a burn because it's the same response. Just in this case the cells aren't physically destroyed by excess direct heating.
