Auckland doctor, Graham Gilbransen, says he has been contacted by more crew members of the Pukaki, which was an observer at atmospheric nuclear tests on Christmas Island during the 1950's. More than a dozen previously untraced crew members came forward after hearing the 'Morning report' programme in which Doctor Gilbransen talked about his survey which shows that nine out of thirty-one former Pukaki crew members have some form of cancer. Fraser Folster reports.
