How 20th century nuclear testing can help scientists detect art forgeries

Researchers from ETH Zurich have refined a process that can detect modern fakes of paintings by measuring excessive levels of the isotope carbon-14 released into the atmosphere through nuclear testing in the 20th century. The new method requires significantly smaller samples of paint than was previously necessary, with a case study demonstrating accuracy dating from a single paint particle weighing under 200 micrograms.
