‘CHAPTER 17 on THE INTERACTION OF SURFACE SHIPS WITH THE THERMAL AND RADIOLOGICAL ENVIRONMENT by R. W. Shnider U.S. Naval Radiological Defense Laboratory San Francisco, California { Originally published as USNRDL~475] 20 January 1964 “was Abstract This chapter considers the interaction of surface ships with the thermal and nuclear radiation fields resulting from water-surface and underwater bursts, but does not include effects on personne]. Two classes of interaction are considered: (1) interaction of the ship with radiations, involving shielding against thermal, neutron, and gamma-radiations; (2) interaction of the ship with materia! particles, involving deposition of radioactivity on the ship's weather surfaces, or ingress of activity within the weather envelope via ventilation or combustion air. The classes of radiation considered include (a) thermal, (b) fireball-plume-cloud, (c) transit, (d) deposit, (e) radiation from contaminated water, (f) radiation from contaminated ventilation or combustion oir. Available weapons-test data are given for shipboord radiation levels due to each class, along with current theoretical methods for assessing the radiation fields at various shipboard locations. 17-1 sem ee
