MONTE CARLO CALCULATION OF GAMMA-RAY PENETRATION OF RIBBED SLABS

Abstract

Data are given in the form of attenuation factors for the exposure due to gamma radiation transmitted by a ribbed slab. The ribbed slab is made of concrete and is similar to one which has been used in experimental studies conducted at the University of Illinois. The source radiation was assumed to be that of Co-60 with source spectrum degradation due to the self-shielding of the source. Four angles of incidence, 0 degrees, 45 degrees, 60 degrees, and 75 degrees, were considered. In addition, the effect of a beam of radiation incident with directions diverging 2.5 degrees on either side of 45 degrees was studied in a rather crude fashion. Attenuation factors for 1.25 McV gamma radiation incident normally on a simulated wood floor are included in an appendix.
