The Second International Conference on Medical Physics, held in Boston, MA, August 11th-15th, 1969. Includes black and white photographs and illustrations, and edited by John Laughlin & Edward 'Ted' Webster. Many will remember both editors and fondly remember the courses they took from these gentlemen at Harvard's Massachusetts General Hospital. This book would be of special historical interest to persons in the fields of radiology, radiobiology, radiation therapy, and medical physics, many of whom are now department chairpersons.
