The physics of nuclear isotopes offers a new opportunity to differentiate fake oil boxes from real ones. The idea is simple: if you find several isotopes spread by atomic bombs, you can know if a picture is before or not 1945, since these isotopes are not found in nature and occur in explosions of atomic bombs. In fact, since 1945 many atomic bombs were exploded, one in Hiroshima and one in Nagasaki, and others in the New Mexico desert.

The analysis technique of the isotopes of the tables detects kesium-137a and extrontzio-90 in oils used after 1945. If the original picture is above, one of the specimens containing these isotopes must be false. This technique has been used and patented by a group of Russians: Elena Braser, restorer of the Russian Museum and Anfrey Krusanov, chemist. Braser himself mentioned that it is a very useful but also very limited technique. A picture that does not contain the isotopes Cesium 137 and Strontium 90 is not necessarily real.
