ABSTRACT:
Described are methods of filling and emptying radiation shields comprising a container formed of thin flexible material.
The method of filling comprises the steps of (a) filling the radiation shield with a gas to form the shield and then (b) replacing the gas with a radiation attenuating liquid.
Additionally, when the shield configuration is not entirely filled with radiation attenuating liquid, either deliberately or due to leakage, an overpressure of gas above the radiation attenuating liquid solidifies the shield in its designed dimensional configuration.
The method of emptying comprises the step of forcing the radiation attenuating liquid out through one or more outlets by forcing a gas into the radiation shield.
