I have conducted a certain amount of research on this subject in order to find out what my father was doing on Christmas Island during Operation grapple Y that launched a weapon code named Dickens just 1.5 miles south of the Island in April 1958.
He died of multiple myelomas in 1985. Luckily, I was sired before his visit there. For an example of the impact upon just one man and his successors, see:
