Scientists and art historians have developed what they say is a foolproof way of identifying forged works of art. They can distinguish between art created before 1945 and that produced after that date by measuring levels of the isotopes caesium--137 and strontium--90. These isotopes do not occur naturally but are released into the environment by nuclear blasts.
