Claims
- 1. A method of filling a radiation shield comprising a free-standing container formed of thin flexible material, said method comprising the steps of:
- first, filling the radiation shield operable to be free-standing with a gas at sufficient pressure to form the shield into its designed dimensional free-standing configuration; then
- second, placing the radiation shield in the desired relationship to a radiation source; and then
- third, replacing the gas with a radiation attenuating liquid which also forms the shield into its designed dimensional free-standing configuration.
- 2. A method as recited in claim 1 wherein said step of filling the radiation shield with a gas comprises
- a step of filling said radiation shield with air.
- 3. A method as recited in claim 1 or 2 wherein said step of replacing the gas comprises the step of:
- replacing the gas with a hydrogenous radiation attenuating liquid which is denser than water.
- 4. A method of solidifying in its designed dimensional configuration a radiation shield comprising a container formed of thin flexible material filled with a radiation attenuating liquid, said method comprising the step of maintaining an over-pressure of gas above the radiation attenuating liquid in the shield so as to maintain the shield in its designed dimensional configuration.
- 5. A radiation shield for use in installations containing sources of radiation, said radiation shield comprising:
- (a) a container being operable to be free standing formed of thin flexible material; and
- (b) a first means for filling said container with a gas so as to cause said container to assume its designed dimensional configuration;
- (c) a second means for emptying the gas from said container;
- (d) a third means for filling said container with a radiation attenuating liquid at the same time that said second means is emptying the gas from said container so as to cause said container to maintain its designed dimensional configuration as the radiation attenuating liquid replaces the gas; and
- (e) a fourth means for emptying the radiation attenuating liquid from said container.
- 6. A radiation shield for use in installations containing sources of radiation, said radiation shield comprising:
- (a) a container formed of thin flexible material;
- (b) a first means for filling said container with a gas so as to cause said container to assume its designed dimensional configuration;
- (c) a second means for filling said container with a radiation attenuating liquid;
- (d) a third means for venting the displaced gas at the same time that said second means is filling said container so as to cause said container to maintain its designed dimensional configuration as the radiation attenuating liquid replaces the gas; and
- (e) a fourth means for emptying the radiation attenuating liquid from said container.
- 7. A method of filling a radiation shield comprising a free-standing container formed of thin flexible materials, said method comprising the steps of:
- placing the radiation shield in the desired relationship to a radiation source;
- filling the radiation shield with a gas of a sufficient pressure to form the shield into its designed free-standing dimensional configuration; then
- replacing the gas with a radiation attenuating liquid which also maintains the shield in its original dimensional configuration.
