|'The Radioactive Man'
by Fred Edge
At an atomic research facility, the caretaker steals a capsule of radioactive material and then makes off. Doctor Keel learns that not only will the stolen isotope kill the thief, but also anyone else who comes into close proximity with it within thirty-six hours of contact. The man mistakenly believes that he is being pursued by the police because of a forged passport, and goes into hiding. When his girlfriend arranges for him to meet someone who will get him safely out of the country, it transpires that the man really intends to kill him for the fee. After Steed provides Keel with a lead, the doctor is able to uncover the thief's whereabouts from his girlfriend. Keel and a doctor from the research facility use a Geiger counter to track the thief and the isotope down in time.
