Chen Lu was born in Lanzhou, People's Republic of China. As an adult, Dr. Lu is a nuclear physicist in the People's Republic of China who is ordered to find a way to defeat the Thunder God Thor after the hero thwarts the Red Army's invasion of India. Hiding away in a laboratory, Lu exposes himself to small doses of radiation until he is able to withstand a massive barrage. Becoming a living "Radioactive Man," Lu displays his new found powers to his superiors and travels to New York City to battle Thor. While the newly-named Radioactive Man is able to initially match Thor, the Thunder God creates a vortex to transport Lu back to China, where he apparently self-detonates.[1]
