Radiation shielding method and apparatus
This patent describes in a system having a pool of liquid in which a radiation emitting component is immersed for shielding the component with respect to radiation emitted by the component, the method of shielding a portion of such component extending above the upper surface of the liquid of the pool. It comprises: surrounding the portion of the upper end of the component which extends above the upper surface of the pool of liquid with a vessel having a top end wall and a side wall. The top end wall being disposed above and spaced form the extended upper end of the component and the side wall extending around and being disposed with the side wall spaced from the sides of the component and with the lower end of the side wall extending into the pool of liquid; and evacuating gas in the vessel to draw liquid from the pool into the vessel until the upper level of the surface of the liquid in the vessel is above the extending upper end of the component.
