If you were to stop time, would things like temperature and radiation still affect you?

I’ve been musing to myself a little bit, and had an interesting idea pop up. If you were to stop time at say, the point of a nuclear explosion, would the extreme heat and radiation still manage to affect you, or would you be able to observe it up close without it affecting you?

Of course this is theoretical, but I’m interested to know what might be the case.
