On the cover: The summary paper of the symposium is dedicated to its co-author, William (Bill) F. Morgan, who became acutely ill at his home right after the paper’s completion. Within a day he passed away on 13 November 2015. With great sadness, Tony Brooks and Ludwig Feinendegen dedicate this paper to Bill in memory of a uniquely wonderful friend and a world class scientist and leader in the field of radiation-biology.
