We lived quite close to a British man who was a Japanese POW. He was in a work party in an air raid shelter some 1/4 mile from the GZ at Hiroshima. He was completely unharmed but did die from extensive cancers some twenty years ago. He was persuaded to gave a couple of lectures but in general would not talk about the experience.

In the article, I think the burns mentioned were really thermal burns, not radiation. Still not good for the recipient though.

I can't understand why, like so many others, she was not blinded when she watched the bomb actually explode.

It is rumoured that the US high command wanted to drop lots of coloured flares before the detonation so the maximum number of people were looking up at the sky on the clear day to maximise casualties.
