A 1 Curie isotropic point source that emits one 400 keV photon per decay is located at the center of a spherical tungsten shield with mass density 19.3 g/cm^3 and atomic mass 183.84 g/mol. with a radius of 2.5 cm. The microscopic cross section of the tungsten at this energy is 55 b. Determine the uncollideed scalar flux a distance of 30 cm away from the source. Negelect photon collisions outside the shield and treat it like a vacuum.
