Complete text of publication follows. Dried almonds, raisins, dates and pistachio were irradiated using gamma radiation and electron beam with an average absorbed dose of 5 kGy. The radiation treatment was detected by ESR spectroscopy. Different parts of the dried fruits were analysed as follows: almonds: skin; raisins: dried pulp (at 30 deg C for one week); dates: dried pulp (at 30 deg C for one week) and stone; pistachio: nutshell. A Bruker ECS 106 EPR Spectrometer, at a microwave power of 0.4 mW, at room temperature was used. The analysis were carried out 2-3 months and 6 months after irradiation. A series of signals, tentatively described as `cellulose-like`, `sugar-like` and `complex` were observed, and some slight differences between spectra recorded from samples irradiated with gamma and electrons were evident.
