Abstract

1,088,811. Irradiation of material immersed in a liquid biological shield. ATOMIC ENERGY OF CANADA Ltd. Jan. 20, 1966 [March 5, 1965], No. 2718/66. Heading H5R. Substances are irradiated beneath the surface of a liquid biological shield material by placing the substance on a float on the surface of the liquid, arranging for a source of radioactive radiation to be disposed under the liquid surface, enclosing the volume of gas in the immediate vicinity of the substance, above the surface of the liquid and sinking the enclosing means beneath the surface of the liquid until the substance and volume of gas it contains are adjacent the radiation source and accomplishing the desired irradiation. The substance may be moved in relation to the source during irradiation so that the irradiation is uniform throughout the whole of the substance. Fresh gas may be introduced into the enclosure after it has been immersed so as to reduce the moisture content and the ozone level of the enclosed volume of gas. The enclosure together with the enclosed gas and substances are brought to the surface if the surrounding liquid approaches the substances being irradiated beyond a predetermined level. The enclosure is preferably a bell-shaped container which can be lowered into a shielding pool to enclose the float and a certain volume of air. Preferably the float comprises cages to receive the substance with means to rotate the cages during irradiation. The radiation source preferably extends upwardly from the bottom of the pool, and the float has an aperture for receiving the source when said float is submerged by the bell, and the float and the bell may be equipped with a locking means to mechanically connect the bell and the float.
