A COMPUTER CODE FOR ESTIMATING THE PROTECTION OFFERED BY SHIPS AGAINST FALLOUT, BASE SURGE, OR WATER POOL RADIATION,

Abstract

The report describes a method for estimating the shielding effectiveness of ships against various types of gamma radiation fields. The method actually can be used for a wide variety of complex structures. The ship or structure is represented by a set of rectangles whose number, orientations, sizes, and thicknesses are variable. The direct radiation is calculated exactly, and the scattered radiation is approximated by buildup factors. It was found that the calculations agree well with experiment if it is assumed that the contribution due to scattered radiation is about half that given by infinite medium buildup factors. (Author)
