抄録

Trace amounts of manganese in steel was determined nondestructively by neutron activation analysis using JRR-1 reactor (neutron flux: 1011 n/cm2·sec). The induced radioactivity of 56Mn was measured with a well type scintillation counter and a γ-ray spectrometer. The results were as follows: (1) The agreement between neutron activation analysis and chemical analysis were within 10%, and the reproducibility of activation analysis were within ±10%. (2) The relative error due to counting fluctuation was 2% for 0.01γ of manganese (2 hrs irradiation). (3) In order to eliminate the influence due to the activity of 64Cu, manganese activity should be counted from 1 to 5 hours after the irradiation for two hours.
