Nunn May did not go to the British Museum meeting, but he was arrested in March 1946 and confessed to espionage. On 1 May 1946, he was sentenced to ten years' hard labour. He was released in late 1952, after serving six-and-a-half years. Nunn May refused to define his actions as treason and claimed in a statement after his release from prison that he believed that he had "acted rightly" as a spy because of being "wholeheartedly concerned with securing victory over Nazi Germany and Japan, and the furtherance of the development of the peaceful uses of atomic energy." Blacklisted from universities in Britain, Nunn May worked for a scientific instruments company and in 1961 he went to work at the

(who was arrested in 1950) he knew little of weapon design. Nunn May is a major character in the 2003 novel ''The Cloud Chamber'', by Clare George, a fictional account of Cambridge physicists in the 1930s which centres on the scientific excitement of the interwar years contrasted with the vexing moral questions faced by scientists during World War II. The main character is a fictional physicist and pacifist who studied and worked at Cambridge's Cavendish Laboratory with Nunn May before the war. George's acknowledged inspiration for the story was her grandfather, a real-life physicist whose true story follows several of the particulars of her character, Walter Dunnachie.
