✦ Synopsis


Irradiated foods can be detected by thermoluminescence (TL) of contaminating minerals. Altogether about 300 lots of herbs, spices, berries, mushrooms and seafood were studied by the TL method. Irradiated herbs and spices were easily differentiated from unirradiated ones two years after irradiation of a 10 kGy dose. The mineral composition of seafood was variable; and while calcite was suitable for the TL analysis, aragonite and smectite gave unreliable results. Control analyses during two years confirmed the reliability of TL method.

The hatchability rate did not show the significant differences between the groups of egg irradiated and the control group (P > 0.05). And the parameters such as average weight, feed conversion and week feed consumption did not show significant differences between the groups of eggs irradiated and th
