Abstract

Measurements are provided (101) as correspond to a floor (201) of a room. This room will typically have space thereunder of sufficient size to accommodate a least one person therein. These measurements are used (102) to provide a bladder (202) that will, when at least substantially filled with liquid, substantially fully cover the floor and provide a radiation barrier to thereby provide corresponding protection to a person in the space under that room. The bladder can have one or more openings (203) to facilitate introducing liquid into the bladder and/or to facilitate removing such liquid when desired. Pumps (608) and/or valves (603) can be utilized, if desired, to facilitate such filling and/or emptying. By one approach, one or more supplemental retrofitable supports (701) can be used in the space beneath the room to provide supplemental vertical support to thereby aid in supporting the weight of the bladder when filled.

Claims

1. A method comprising:

providing measurements as correspond to a floor of a particular room, which particular room has space thereunder sufficient to accommodate at least one person;

using the measurements to provide a corresponding bladder that will, when at least substantially filled with liquid, substantially fully cover the floor and provide a radiation barrier to thereby provide corresponding protection to a person in the space.

2. The method of claim 1 wherein using the measurements to provide a corresponding bladder comprises providing a bladder that is sized to provide a radiation barrier, when at least substantially filled with liquid, of at least ten inches in depth.

3. The method of claim 2 wherein providing a bladder that is sized to provide a radiation barrier, when at least substantially filled with liquid, of at least ten inches in depth comprises providing a bladder that is sized to provide a radiation barrier, when at least substantially filled with liquid, of at least thirty inches in depth.

4. The method of claim 1 wherein using the measurements to provide a corresponding bladder comprises providing a bladder that is formed, at least in part, of radiation-blocking fabric.

5. The method of claim 4 wherein providing a bladder that is formed, at least in part, of radiation-blocking fabric further comprises providing a bladder that is formed, at least in part, of:

radiation-blocking fabric;

flexible waterproof material.

6. The method of claim 1 wherein using the measurements to provide a corresponding bladder comprises providing a bladder having an opening formed therein to receive liquid therein.

7. The method of claim 6 further comprising:

providing a length of liquid-bearing conduit that is operably coupleable to the opening to facilitate filling the bladder with liquid.

8. The method of claim 7 wherein providing a length of liquid-bearing conduit further comprises providing measurements as correspond to a relative planned position of the bladder in the room with respect to a particular source of liquid.

9. The method of claim 6 further comprising:

providing a fullness-responsive valve that is operably coupleable to the opening to thereby automatically limit the liquid as enters the bladder such that filling of the bladder to a useful level can be conducted in an absence of human supervision.

10. The method of claim 9 wherein providing a fullness-responsive valve comprises providing at least one of:

a level responsive valve;

a flow quantity sensitive valve;

a time sensitive valve;

a pressure sensitive valve.

11. The method of claim 1 further comprising:

providing a supplemental retrofitable support that is configured and arranged to fit within the space and provide vertical support to the room to thereby aid in supporting the bladder when the bladder is disposed in the room and filled with liquid.

12. The method of claim 11 wherein providing a supplemental retrofitable support comprises using measurements regarding vertical space within the space to configure and arrange the supplemental retrofitable support.

13. The method of claim 11 wherein providing a supplemental retrofitable support comprises providing a telescoping supplemental retrofitable support.

14. The method of claim 1 wherein using the measurements to provide a corresponding bladder comprises providing a bladder formed, at least in part, of an elastic material such that the bladder will, when at least substantially filled with liquid, automatically become elongated to thereby facilitate substantially fully covering the floor.

15. The method of claim 1 wherein the liquid comprises water.

16. The method of claim 1 wherein using the measurements to provide a corresponding bladder comprises providing a bladder formed of at least two layers of material to thereby facilitate resistance to leakage.

17. The method of claim 1 wherein using the measurements to provide a corresponding bladder comprises providing a bladder that further comprises a radiation exposure indicator.

18. The method of claim 1 further comprising:

providing a reversible pump to facilitate filling and emptying the bladder.

19. A radiation-blocking apparatus comprising:

a watertight bladder that is configured and arranged to lie on the floor of and fit within and substantially conform to a particular room, which particular room has space thereunder sufficient to accommodate at least one person;

an opening disposed through the watertight bladder to facilitate receiving liquid therethrough such that the watertight bladder, when at least substantially filled with liquid, provides radiation-blocking protection for a person disposed in the space.

20. The radiation-blocking apparatus of claim 19 wherein the watertight bladder is sized to provide a radiation barrier, when at least substantially filled with liquid, of at least ten inches in depth.

21. The radiation-blocking apparatus of claim 20 wherein the watertight bladder is sized to provide a radiation barrier, when at least substantially filled with liquid, of at least thirty inches in depth.

22. The radiation-blocking apparatus of claim 19 further comprising:

radiation-blocking fabric disposed about at least a portion of the watertight bladder.

23. The radiation-blocking apparatus of claim 22 wherein the radiation-blocking fabric is disposed substantially about the entire watertight bladder.

24. The radiation-blocking apparatus of claim 19 wherein the watertight bladder is formed, at least in part, of flexible waterproof material.

25. The radiation-blocking apparatus of claim 19 further comprising:

a length of liquid-bearing conduit that is operably coupleable to the opening to facilitate filling the watertight bladder with liquid.

26. The radiation-blocking apparatus of claim 25 wherein the liquid-bearing conduit has a length that corresponds to a relative planned position of the watertight bladder in the room with respect to a particular source of liquid.

27. The radiation-blocking apparatus of claim 19 further comprising:

a fullness-responsive valve that is operably coupleable to the opening to thereby automatically limit the liquid as enters the watertight bladder such that filling of the watertight bladder to a useful level can be conducted in the absence of human supervision.

28. The radiation-blocking apparatus of claim 27 wherein the fullness-responsive valve comprises at least one of:

a level responsive valve;

a flow quantity sensitive valve;

a time sensitive valve;

a pressure sensitive valve.

29. The radiation-blocking apparatus of claim 19 further comprising:

a supplemental retrofitable support that is configured and arranged to fit within the space and provide vertical support to the room to thereby aid in supporting the watertight bladder when the watertight bladder is disposed in the room and filled with liquid.

30. The radiation-blocking apparatus of claim 29 wherein the supplemental retrofitable support comprises a telescoping supplemental retrofitable support.

31. The radiation-blocking apparatus of claim 19 wherein the watertight bladder comprises, at least in part, an elastic material such that the watertight bladder will, when at least substantially filled with liquid, automatically become elongated to thereby facilitate substantially fully covering the floor.

32. The radiation-blocking apparatus of claim 19 wherein the liquid comprises water.

33. The radiation-blocking apparatus of claim 19 the watertight bladder is comprised of at least two layers of material to thereby facilitate resisting leakage.

34. The radiation-blocking apparatus of claim 19 wherein the watertight bladder further comprises a radiation exposure indicator.
