He was reportedly cast after Tony Owen of Todon saw Nelson on an episode of Studio One. Filming started in England on 4 February 1955. It was shot at Merton Park Studios. The Isotope Man Maine turned the script into a novel, The Isotope Man, published in 1957. It would be the first of three novels about reporter Mike Delaney. The New York Times called the novel "fairly crude and preposterous but lively enough". The Los Angeles Times called it "near perfect entertainment for the radioactive age." Critical reception TV Guide called it a "dumb movie with an interesting premise"; and AllMovie similarly thought its "absolutely fascinating premise" unfortunately translated into "lack of imagination in the script"; but from an able cast, Faith Domergue was "especially welcome", and the reviewer concluded "The budget is clearly low, but (Ken) Hughes does well with what he has."
