Section: claims

1. A radiation shield suitable for preventing radiation or radioisotopes from reaching or contacting a person using a vessel containing a radioactive solution, said shield comprising: a radiopaque container having a top and a bottom opening; and  means for supporting said vessel within said container without said means blocking said top or bottom opening, wherein said container reduces emission of said radiation through the sides of said vessel.  providing a radiation shield having a radiopaque container with a top and bottom opening; and  means for supporting said vessel within said container without blocking said top or bottom openings, wherein said container reduces emission of said radiation through the sides of said vessel;  placing said vessel within said radiopaque container; and  transporting said vessel from a first position to a second position by holding said container without touching said vessel. 2. The radiation shield of claim 1 wherein said radiopaque container comprises means to permit incubation liquid to directly enter the bottom opening of said container and surround that portion of said vessel containing said radioactive solution. 3. The radiation shield of claim 1 wherein said container is a sleeve that fits over said vessel. 4. The radiation shield of claim 3 wherein said sleeve has a substantially flat bottom surface for allowing said sleeve to rest in a free-standing position on a flat surface. 5. The radiation shield of claim 3 wherein said container is sized and shaped to hold a microtube having a lid and comprises a ridge or dimples formed along said top opening to elevate the lid of the microtube from the sleeve to facilitate access to the lid. 6. The radiation shield of claim 3 wherein said sleeve comprises a flange for allowing suspension of said sleeve in a rack, wherein liquid may enter the bottom opening of said sleeve and surround that portion of said vessel containing said radioactive solution. 7. The radiation shield of claim 1 wherein said radiopaque container comprises an incubation rack for supporting a plurality of vessels and a radiopaque shield formed along the perimeter of said rack. 8. The radiation shield of claim 7 further comprising a radiopaque cover for shielding radiation emanating through said top opening. 9. The radiation shield of claim 1 wherein said radiopaque container comprises a block of radiopaque material having a plurality of bores. 10. The radiation shield of claim 1 wherein said container is transparent. 11. The radiation shield of claim 1 wherein said container is fabricated using acrylic, polycarbonate or other subtantially radiopaque plastic material. 12. A method for preventing radiation or radioisotopes from reaching or contacting a person using a vessel containing a radioactive solution, said method comprising the steps of: 13. The method of claim 12 further comprising the step of placing said radiopaque container comprising said vessel within an incubation liquid whereby said vessel is caused to attain the temperature of said liquid.
