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.

You need a graphic understanding of a situation to make a complete judgment and we didn't have that.

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

What I had said in the morning was that this is what we know has happened, but there has been no significant off-site release. Only to find out moments later that, in fact, there had been an off-site release. I still haven't gotten over that.

And I remember walking in there and, I must say, I was quite unnerved the closer I got to 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.

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.
