A nuclear pile contains control rods, with a density of 1.04 x 104 kg/mʼand composition by weight of 95% Ag, 5% Cd, which have thermal neutron absorption cross-sections of 63 b and 2520 b respectively. Assuming thermal neutrons pass through a control rod 2.5 mm thick, calculate what fraction of neutrons will be absorbed by the control rod. {8} [The atomic mass of Ag is 106.905 u and Cd is 113.903 u, where lu = 1.6605 x 10-27 kg. A barn is defined as 1 b= 10-28 m2.]
