1. The problem statement, all variables and given/known data A 1.0g Co(59) target is exposed to a constant fluence rate of thermal neutrons equal to 1E+12 n cm-2 s. Cross section (n,gamma) is 37.18barn and density is 8.9g cm3. What is the initial exposure rate at 1 meter due to neutron capture? 2. Relevant equations 1R=2.58e-4C/kg gamma = 7.49MeV 3. The attempt at a solution I calculated on the order of 10^6 R/hr. Just curious to see if that value is reasonable for 1 gram of Co59 being exposed.
