Applications of the low-background gamma spectroscopy to the geographical origin of marine salts and prunes
F. Perrot1

The low background gamma spectroscopy has been applied to try to sign the geographical origin of the French atlantic marine salts and of the prunes from Agen. Most of the activity measurements have been done using low background Ge spectrometers located in Bordeaux. Results have shown that a clear signature exists in the case of the French atlantic salts using the $^{40}$K, $^{137}$Cs and $^{226}$Ra isotopes but not in the case of the prunes.
