The facility of claim 1, wherein the at least one shielding barrier comprises a plurality of walls and provides protection against the radiation for a person located outside the room, or provides protection for a radio sensitive object or an electronic device located outside the room. 4. The facility of claim 1, wherein the at least one shielding barrier comprises a plurality of walls and provides protection against the radiation for a person located inside the room or provides protection for an electronic device located inside the room. 5. The facility of claim 1, wherein the radiation shielding fill material comprises at least fifty percent by weight of at least one of magnetite or hematite based on the total weight of the radiation shielding fill material. 6. The facility of claim 1, wherein the at least one wall comprises a plurality of removable panels that are combinable to form the at least one wall. 7. The facility of claim 6, wherein the plurality of removable panels are constructed to be assembled together by aligning one panel with another panel. 8. The facility of claim 6, wherein the plurality of removable panels are constructed to be assembled together by aligning one panel of the plurality of removable panels above or below another panel of the plurality of removable panels. 9. The facility of claim 6, wherein the plurality of removable panels are constructed to be assembled together by aligning one of the plurality of removable panels on either side with another panel of the plurality of removable panels. 10. The facility of claim 6, wherein the radiation shielding fill material is removable or replaceable. 11. The facility of claim 6, wherein the plurality of removable panels are transportable to a construction site for assembling at the construction site to create the at least one wall. 12. The facility of claim 6, wherein the plurality of removable panels can be recombined to change: a shape of a shielded void space, change a shape of a shielded room, to increase shielding or to decrease shielding. 13. The facility of claim 6, wherein the radiation shielding fill material is positioned between at least two of the plurality of removable panels. 14. The facility of claim 6, wherein the plurality of removable panels comprise a shippable module having conduit or ducts placed therein prior to shipping to a construction site. 15. The facility of claim 6, wherein at least one of the plurality of removable panels can be removed while other of the plurality of removable panels maintain shielding or maintain structure for the facility. 16. A method of providing a facility comprising:providing a plurality of shielding modules to form at least one compartment of at least one shielding barrier, wherein a thickness of the at least one shielding barrier is 0.5 meter to 6 meters; andproviding radiation shielding fill material comprising at least fifty percent by weight of an element having an atomic number from 12 to 83 for filling the at least one compartment. 17. The method of claim 16, wherein the at least one shielding barrier provides shielding for a person, a radio sensitive object or an electronic device against radiation radiating from a source opposite the at least one shielding barrier from the person or the electronic device. 18. The method of claim 16, wherein the at least one shielding barrier comprises a plurality of walls forming a room and the at least one shielding barrier provides protection against radiation originating inside of the room for a person located outside the room, or provides protection for a radio sensitive object or an electronic device located outside the room. 19. The method of claim 16, wherein the at least one shielding barrier comprises a plurality of walls forming a room and the at least one shielding barrier provides protection against the radiation originating outside of the room for a person located inside the room, or provides protection for a radio sensitive object or an electronic device located inside the room. 20. The method of claim 16, wherein the radiation shielding fill material comprises at least fifty percent by weight of at least one of magnetite or hematite based on the total weight of the radiation shielding fill material. 21. The method of claim 16, wherein the plurality of shielding modules each have at least one side comprising a metal wall. 22. The method of claim 16, wherein the plurality of shielding modules are a plurality of prefabricated modules. 23. The method of claim 22, further comprising shipping the plurality of prefabricated modules to a construction site. 24. The method of claim 22, further comprising assembling together the plurality of prefabricated modules at a construction site by aligning one of the plurality of prefabricated modules with another of the plurality of prefabricated modules. 25. The method of claim 22, wherein the radiation shielding fill material is positioned between at least two of the plurality of prefabricated modules. 26. The method of claim 16, wherein the at least one shielding barrier comprise a plurality of shielding barriers forming a room within a room. 27. The method of claim 16, wherein the radiation shielding fill material is removable, or the radiation shielding fill material is replaceable with another radiation shielding fill material. 28. A method for providing a facility comprising:assembling a plurality of prefabricated modules to create a shielding barrier; andfilling at least one compartment of the shielding barrier with a radiation shielding fill material, wherein a thickness of the at least one shielding barrier is 0.5 meter to 6 meters and the radiation shielding fill material comprises at least fifty percent by weight of an element having an atomic number from 12 to 83. 29. The method of claim 28, wherein the at least one compartment comprises a plurality of compartments including a first compartment and a second compartment. 30. The method of claim 29, wherein in the filling step, the first compartment is filled with the radiation shielding fill material and the second compartment is not filled with the radiation shielding fill material. 31. The method of claim 29, wherein in the filling step, the radiation shielding fill material of the first compartment is different from the radiation shielding fill material of the second compartment. 32. The method of claim 28, wherein the radiation shielding fill material is replaceable with a different radiation shielding fill material having different shielding properties. 33. The method of claim 28, wherein the radiation shielding fill material is removable from the at least one compartment.
