Earl Ubell is a pioneer among science and health writers in America. After a long, distinguished career at The New York Herald Tribune from 1943 to 1966, he went on to work at both CBS and NBC News. Prominent in the emerging scientific writing community in the 1950s and early 1960s, he was a recipient of the Lasker Medical Journalism Award 1957. Milton Stanley Livingston was a leading physicist in the field of magnetic resonance accelerators. Working first with professor Ernest O. Lawrence at the University of California, Livingston was instrumental in the development of the Berkeley cyclotron. Moving to Cornell in 1938, Livingston was part of the core group who established nuclear physics as a field of study. Choosing to stay with the Cornell cyclotron rather than follow colleagues onto the Manhattan Project, Livingston was involved in the production of radioisotopes for medical purposes. At the time of this interview, Livingston was director of the Cambridge Electron Accelerator, a joint project of Harvard University and MIT.In this program segment Louis Lyons quizzes Earl Ubell about the lack of public knowledge and the perception of the nuclear bomb, while pressing Professor Livingston to explain exactly what nuclear fallout is, and the danger it presents.
