The detection sensitivities for 71 elements which exist in nature, with<br />respect to neutron activation analysis, have been calculated and presented. The paper defines the<br />sensitivity as log (peak area/weight) produced for different radionuclides suitable for activation analysis<br />using five sets of experimental conditions. Although, the current sensitivity factors have been calculated<br />for miniature neutron source reactor (MNSR) having thermal neutron flux of 1012 cm-2 s-1; however, the<br />general pattern of elemental sensitivities will not be affected drastically by changing reactor type.<br />Normalized peak areas have also been presented for the identification of suitable activation products.<br />These normalized areas are independent of experimental conditions used and are therefore general in<br />nature. Finally, real data have been presented from our previous studies, which confirm present findings<br />and provide actual irradiation times along with useful gamma-rays used in the analysis.</p> ER -
