A Nagasaki survivor and physician recounts his life's work
Dr. Masao Tomonaga was only 2 years old when the United States bombed his home city of Nagasaki. He survived, and grew up to become a physician for other survivors, known as hibakusha. He also studied hematology, and his research on leukemia and myelodysplastic syndromes was foundational for understanding how radiation affects the body.
In August 2025, the 80th anniversary of the bombings of Hiroshima and Nagasaki, he spoke with Host Ira Flatow about his life’s work, how hibakusha lived with the medical consequences of the bombs, and his message to the world.
