This question already has an answer here:
I read (the beginning) of a short story about a man who invented nanobots. He went into a radioactive room (nuclear reactor) where he trapped himself and started reading a book.
It may have been a short story written by Isaac Asimov, but I am not sure.
As far as I can remember, it was in a collection of short stories. I also remember that during that time, I read Asimov's Science Fiction. It was supposed to be continued on the next volume, but I did not find that volume.
I read that sometime between 1988 and 1992... but it was a bit older, when I read it.
