By Thursday morning, we'd gotten over the worst of it.

And at ten, or whatever time, in the morning we had the press conference, what we knew is there had been an incident at Three Mile Island, that it was shut down, that there was water that had escaped but it was contained.

There were schools and hospitals who were ready to take people with undescribed injuries, but not necessarily ready to take people with severe radiation poisoning.

Nobody could tell us or really had a very good idea, if there were a massive release of radiation, what kind of medical treatment people were going to need and this or that, or, indeed, whether there would be medical personnel around.

My time inside there was very short compared to the amount of time it took to take on and take off this suit and to test me for how much radioactivity I have.

And if you're not going to have a clear health threat, you don't want to panic people.

The first one, obviously, was walking into my office at eight o'clock in the morning on Wednesday, and being told there was a telephone call saying that there was an incident at Three Mile Island, and that it had shut down and that beyond that we didn't know.
