The invention claimed is: 1. A radiation protection shield for protecting medical personnel from radiation being applied to a patient positioned on a table, the shield comprising: a frame having a plurality of vertical supports that divide a radiation-source side of the frame from a user side of the frame; a primary screen including a radiation-resistant material, the primary screen connected to said frame; a secondary screen slidably connected to the primary screen so that the secondary screen is moveable along a plane defined by the plurality of vertical supports to one of a retracted configuration and an extended configuration; and an upper flange extending (i) across at least a portion of the frame and (ii) from a top region of the secondary screen and towards the radiation-source side of the frame, the upper flange effective in reduction of radiation scatter; wherein the upper flange effectuates reduction of radiation scatter in both of the first retracted configuration and the extended configuration; the shield further comprising a shelf having (i) a shelf outer end on a side of the shelf adjacent to an outer end of the frame and (ii) a shelf inner end on a side of the shelf opposite to the shelf outer end, the shelf having a varying width that is wider at the shelf outer end than the shelf inner end. 2. The radiation protection shield as set forth in claim 1, wherein the primary screen includes a lead-impregnated acrylic. 3. The radiation protection shield as set forth in claim 1 further comprising: a plurality of rollers attached to a bottom of the frame to allow a lower shield to move along a floor that the shield is positioned on during use of the radiation protection shield. 4. The radiation protection shield as set forth in claim 3, wherein said rollers are lockable to restrict the rollers from moving thereby limiting movement of the lower shield. 5. The radiation protection shield as set forth in claim 1, wherein the secondary screen includes a lead-impregnated acrylic. 6. The radiation protection shield as set forth in claim 1, wherein: the primary screen and secondary screen are curved forming an inner concave surface on the radiation-source side of the frame and an outer convex surface opposite the concave surface on the user side of the frame; and the inner surface is positioned adjacent a radiation source during use of the system. 7. The radiation protection shield as set forth in claim 1 further comprising: a hand rail connected to said primary screen to facilitate moving of a lower shield. 8. The radiation protection shield as set forth in claim 1 further comprising: a toe flange extending downward from the primary screen. 9. The radiation protection shield as set forth in claim 1 further comprising: a kick plate positioned adjacent a lower edge of the shield for protecting the primary screen and for medical personnel to use to move a lower shield. 10. The radiation protection shield as set forth in claim 1 further comprising: an upper flange extending from a top region of the shield to form a right angle with the primary screen. 11. The radiation protection shield as set forth in claim 1, further comprising: an upper flange extending from a top region of the shield to form a right angle with the secondary screen. 12. The radiation protection shield as set forth in claim 11 further comprising: an upper shelf extending from the top region of the shield adjacent said upper flange to form a right angle with the secondary screen. 13. The radiation protection shield as set forth in claim 12, wherein said upper shelf extends farther from the secondary screen than the upper flange extends from the secondary screen. 14. The radiation protection shield as set forth in claim 12, wherein the upper shelf is positioned adjacent an end of said shield. 15. The radiation protection shield as set forth in claim 14 further comprising: an upper shelf extending from a top region of the shield. 16. The radiation protection shield as set forth in claim 15, wherein said shelf includes a lead-impregnated acrylic. 17. The radiation protection shield as set forth in claim 1, wherein, the secondary screen is connected to the plurality of vertical supports; and the frame includes sleeves receiving the plurality of vertical supports. 18. The radiation protection shield as set forth in claim 17 further comprising: springs attached to the frame adjacent said sleeves for providing an upward force to the secondary screen by way of said rods. 19. The radiation protection shield as set forth in claim 17 further comprising: a locking mechanism attached to the frame adjacent said sleeves for selectively locking the rods in place in the sleeves thereby locking the secondary screen in place with respect to the primary screen. 20. A radiation protection shield for protecting medical personnel from radiation being applied to a patient positioned on a table, the shield comprising: a frame having a radiation-source side and a user side; multiple screens telescopically connected to each other in a vertical direction along the frame so that an overall height of the shield can be selectively adjusted during use of the shield, an upper flange extending (i) across a first portion of the frame and (ii) from a top region of the secondary screen and towards the radiation-source side of the frame, the upper flange effective in reduction of radiation scatter, and a shelf extending (i) across a second portion of the frame and (ii) from the top region of the secondary screen and towards the radiation-source side of the frame, the shelf having (i) a shelf outer end on a side of the shelf adjacent to an outer end of the frame and (ii) a shelf inner end on a side of the shelf opposite to the shelf outer end, the shelf having a varying width that is wider at the shelf outer end than the shelf inner end. 21. A radiation protection shield as set forth in claim 1, further comprising: a toe drape angled toward the radiation-source side of the frame.
