A biography of the Japanese radiologist who survived the atomic bomb in Nagasaki. Takashi Nagai (1908-1951) was a married Japanese scientist with two children. He generously promoted modern medicine in his country at the expense of his own health. The exercise of radiology gave him a leukaemia that did not, however, prevent him from continuing with a life of intense work. He survived six years of the Nagasaki atomic bomb, most of them bedridden.
He passed from Shinto to atheistic rationalism and later, having resolved his doubts and clarified the relationship between faith and reason, and drawn by the example of life of the Christians he knew, he embraced his vocation with all its consequences. This is a truly impressive and moving story.
