COMPUTATION OF ACTIVITIES INDUCED BY 14-MEV NEUTRONS FOR THE ELEMENTAL ANALYSIS OF HUMAN TISSUES, SKIN AND TOOTH ENAMEL

For planning experiments for neutron activation analysis investigations at 14 MeV, suitable induced beta activities in Bq/g/neutron flux have been computed via appropriate reactions for the estimation of F-19, Na-23, Mg-24, P-31, S-35, Cl-35, Cl-37, K-39, Ca-40, Mn-55, Fe-56, Zn-66, Cu-63, Cu-65, Ag-107, Ag-109 and Pb-208. The computational work for (n,p); (n,alpha); (n,n') and (n,2n) reactions induced with 14 MeV neutrons are based on the pre-equilibrium emission mechanism and also the compound nucleus theory with optical model potential and pairing energy corrections. The cross-sections obtained by pre-equilibrium computer codes are reasonable and have been used in the present computations.
