(2014): Evaluation of chronometers in plutonium age determination for nuclear forensics: What if the 'Pu/U clocks' do not match?
J RADIOANAL NUCL CH. 2014; 302(1): 399-411. FullText FullText_BOKU

This article discusses the age dating results of plutonium/uranium chronometers with a focus on the consequences for age plutonium determination when the basic assumptions of the methodology are not fully met: Incomplete removal of the daughter nuclides at the production date and uranium contamination of plutonium samples. In addition to the Pu-238/U-234, Pu-239/U-235 and Pu-240/U-236, the Pu-242/U-238 chronometer is discussed. The Pu-242/U-238 radiochronometer has only scarcely been used, due to its high sensitivity to residual uranium. However, it can be a very useful indicator for uranium contamination of aged plutonium samples.
