Notes:
The use of Nickel-59 as an excitation source for the X-ray fluorescence analysis of carbon and low alloy steels has been investigated. Nickel-59 has a half life of 80 000 y and is essentially a pure source of cobalt K X-rays. It is ideal as an X-ray source for field systems because the encapsulated source is small, rugged and requires no external power or maintenance. The prototype system require ∼2½ minutes to obtain a manganese analysis, and 15 minutes to determine vanadium, chromium and manganese concentrations. These times could be shortened about a factor of 40 with a more intense excitation source and a larger area detector. The feasibility of portable field systems is discussed.
