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

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.

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 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.

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

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