1. An irradiation facility for controllably irradiating products with gamma-rays comprising:
- (a) a radiation source;
(b) means for loading a plurality of product to be irradiated on a carrier means;
(c) conveyor means for conveying product carrier means to two movable dwell units positioned in parallel proximity of the radiation source, said carrier means supportable by said movable dwell units such that said dwell units carry said carrier means when said dwell units move, said dwell units capable of maintaining constant spatial orientation of said carrier means relative to said radiation source;
(d) means for adjusting the position of the movable dwell units on either side of the radiation source;
(e) means for adjusting the position of the product carrier means on the dwell units;
(f) means for storing the radiation source in a radiation protective storage tank, which comprises a water-filled storage pool or a dry storage shielding cask;
(g) means for moving irradiating source into position for applying irradiating dosage to each carrier; and
(h) computer-linked sensor means therefor;
the irradiation facility having a radiation shielding wall enclosure open at one end, which end also comprises a recessed interior wall complex located for barrier-free conveyance of products to and from the radiation source.

Abstract
The invention describes the facility and method for controllably irradiating materials with gamma rays. Specifically, the invention concerns the processing of foodstuffs, medicines and other products by remote-controlled exposure to a radiation source while being transported by pallet carriers at adjustable distances in two parallel roller type assemblyline toting systems. A further feature of the invention is the computer-linked automated dosimetry system which is used to afford an effective protocol for product preservation, sanitization or sterilization as well as safety.

15. A method for controllably irradiating a product with gamma-rays in an irradiation facility, comprising the steps of:
-
(a) placing the product to be irradiated in a carrier means mounted on a roller conveyor means; (b) moving the carrier means on the conveyor means with connecting shuttle means to different positions on parallel conveyor tracks in proximity of the radiation source; (c) adjusting the distance of the parallel conveyor tracks respective the radiation source; (d) placing the radiation source into position for irradiation; (e) irradiating the product with a radiation dosage while maintaining constant orientation positions of said carrier means relative to said radiation source; and (f) optionally monitoring by a sensor means and controlling by the remote control means, the position of the parallel conveyor tracks, the placement of the radiation source, and the dosage of irradiation. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
