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 19F, 23Na, 24Mg, 31P, 32S, 35,37Cl, 39K, 40Ca, 55Mn, 56Fe, 66Zn, 63,65Cu, 107,109Ag and 208Pb. 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 otpical 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.
