CALIBRATION OF MANGANESE AND GOLD FOILS FOR RELATIVE NEUTRON FLUX MEASUREMENTS
Journal Article
·
· Brit. J. Appl. Phys.
The usual method of intercalibrating foils for relative flux measurements, made by comparing the beta /sup -/ activities of the foils after exposure to the same neutron flux, was compared with a method dependent on weighing the foils. The mass intercalibrations agree to within plus or minus 1% of the activity intercalibrations for gold and manganese foils in the range 90 to 100 mg/cm/sup 2/ thick if a theoretical correction estimating the beta /sup -/ absorption in the foil is applied to the measured mass values.
