<I>Citrus Unshiu</I> ("Satsuma" orange) was irradiated by electrons of 0.2-1.5MeV, from both sides with inversion of the fruit, and dose distribution on the surface of fruit was determined by cellulosetriacetate film(CTA)as a dosimeter. When the fruit was irradiated on the center-line of conveyor, the dose on the equator of fruit increased with an increase of energy of electrons. This implies that the equator of fruit is exposed doubly. Therefore, dose uniformity of surface decreased with increasing energy of electrons. On the other hand, when the fruit was irradiated at the position far from the center-line of conveyor, the direction of electrons to a fruit affected dose distribution on the surface, and consequently dose uniformity decreased. The exposure dose distribution and the direction of electrons seem to be most important for the dose uniformity onthe surface of fruit.
