PENETRATION OF PLANE NORMAL GAMMA RAYS THROUGH SLABS OF ALUMINUM AND STEEL. III. PROCESSED NUMERICAL DATA,
Abstract
This report presents in tabular and graphical form data from experimental measurements of scattered gamma radiation from slabs of aluminum and steel. Monoenergetic gamma rays from Cs137 and Co60 sources with plane-normal incidence were used as irradiation sources. Detection angles used were 5, 10, 20, 30, 45, and 60 deg with effective thicknesses of one, two, three, four, and five 'mean-free-paths' of slab material. Since it was desirable to have spectra for larger angles (75 and 85 deg), a method of extrapolation was devised. The extrapolated spectra are presented in the text. Also included in this report are calculations of dose and buildup factors. There is also shown (in graphical form) how the over-all dose rate is affected by the added extrapolated spectra. (Author)
