Liquid scintillation techniques are shown to be approximately 20 times more sensitive than solid crystal techniques for the determination of beta activity in metal chips cut with an irradiated tool bit. Relative tool wear can be determined easily by simply immersing the metal chips in a suitable counting solution. Total wear can be determined accurately by extracting the radioactive tracer from the chips and comparing it with the specific activity of the tool bit. Author
