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

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.

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.

Another very strong image from the first day was giving my initial press conference in the morning - going down and finding out that everything I had said, the essence of what I had said, was wrong.

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.

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.

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.
