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

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

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

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.

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.

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.

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.
