I've just finished the chapter about radiation therapy in Siddhartha Mukherjee's (amazing) The Emperor of All Maladies: A Biography of Cancer (put aside 10 minutes to read this great New Yorker review)
And tomorrow on the radio I'm going to be talking about Lauren Redniss's Radioactive: Marie and Pierre Curie - A Story of Love and Fallout.
