Abstract:
:The k0 standardization method was adapted for NAA with stable low-flux reactors where flux monitors are not needed. The modified k0 method offers the convenience of the use of libraries of sensitivity constants. It was compared to the relative method for 52 elements using a SLOWPOKE reactor and 6 counting geometries. The sensitivity constants determined from k0 values were found to be as accurate or more accurate than those measured with standards. NAA with this modified k0 method should be accurate to 3% for light elements and 5% for heavy elements.
