After the war, Radwan immigrated to Northeastern Ohio in the United States. He traveled as a wrestler and strongman performing feats such as straightening horseshoes, pulling cars with his teeth, bending quarters, and reclining on a bed of nails while volunteers stones on his chest. For twenty years, Radwan was undefeated as a professional wrestler. Radwan lived in Cleveland, Ohio, where he was a member of several Polish fraternal organizations and clubs. He hosted a Polish language radio show on Sundays and wrote for two Polish language newspapers. He was also a body guard for local politicians, such as former Mayor
Ralph Perk. His popularity among Polish-Americans in Cleveland was valuable to local politicians. A movie about his life titled
The Atomic Man was discussed but never made. ==Death==
