(Sfap) 4. The gold, fast, and shield corrections are added and this value is subtracted from the uncorrected gamma dose to give a corrected gamma dose: 17,500r - (408 + 3590 + 1230) = 12,272@r = 12, 300r of 5. To correct for the gamma attenuation of the shield, gamra attenuation factors for each shield type were calculated for gamma energies of 1, 3, and 5 MeV using _1 to calculate the attenuation factor. The @ ~ bX ‘ appropriate attenuation tactor for the slant range and shot yield was multiplied by the corrected gamma dose to obtain the final corrected gamma dose: 12,300r x 1.14 = 14,022r = 14,000r. (SARD) 6. To save time, "magic numbers" which are the soil gamma dose for 1x10’? thermal neutrons perrsquare centimeter and for 1x10" fast neutrons per square centimeter were calculated for Nevada-type soil, coral, and water using the methods outlined in Reference 5. 222 To calculate
