Abstract : The report first makes a theoretical analysis of the penetration of gamma radiation through a shield consisting of two slabs at right angles to one another and then applies the results of such an analysis to the problem of fallout radiation penetration in-and-down through the walls and floor of a blockhouse into a basement. Certain assumptions are made to simplify the basic calculations to be considered. Comparisons are made with theoretical results of other workers; and an effort is made to reproduce data available from experimental blockhouse work. Discrepancies between results are discussed. Comparisons with the Engineering Manual approach to overhead barrier factor predictions are made. Effect of wall height and structure eccentricity on this barrier factor are predicted. (Author)
