1. An apparatus that acts as a shield for radiopharmaceuticals and protects from radioactivity comprising: a) a first body with a first hollow core that is open on a first edge and a second edge of said first body, said first hollow core for housing a hypodermic syringe;  b) a second body with a second hollow core that is open on a first edge of said second body, said second hollow core for housing said hypodermic syringe;  c) a third body with a third hollow core that is open on a first edge of said third body, said third hollow core for housing said hypodermic syringe;  d) said hypodermic syringe capable of containing a radiopharmaceutical;  e) a first connection means wherein said first body releasably communicates with said second body for providing protection from radioactivity emitted by the radiopharmaceutical;  f) a second connection means wherein said first body releasably communicates with said third body for providing protection from said radioactivity; and  g) said second body further comprising a means for compressing said hypodermic syringe to eject said radiopharmaceutical from the hypodermic syringe while said first body is in communication with said second body. 2. The apparatus as claimed in  claim 1  wherein said first body, second body and third body are constructed from a plurality of radiation shielding materials. claim 1 3. The apparatus as claimed in  claim 1  wherein said means for compressing said hypodermic syringe comprises: claim 1 a) an internal sleeve, slidably and rotatably communicating with the interior surface of said second body and capable of partially extending outside of said second body through slots formed in said second body""s second edge;  b) at least one disk guide inside said second body and parallel to the long axis of said second body and extending the length of said second body;  c) an actuator cap fixedly attached to said internal sleeve and positioned to block said radiation emitted from the second edge of said second body, said actuator cap engaged by said at least one disk guide;  d) a disk having an at least one guide notch in slidable communication with said at least one disk guide such that the disk is prevented from rotating relative to said second body;  e) said disk further having at least one engagement notch;  f) at least one disk engagement tooth on the inside surface of said internal sleeve, said tooth positioned such that when the internal sleeve is selectively rotated to a position, said internal sleeve can be extended from and retracted into said second body without bringing said at least one engagement tooth into communication with the disk and when the internal sleeve is selectively rotated to any other position said at least one engagement tooth engages the disk when the actuator cap is compressed;  g) wherein said at least one engagement notch is sized slightly larger than said at least one disk engagement tooth. 4. The apparatus as claimed in  claim 1  wherein said means for compressing compresses said hypodermic syringe by being partially extended from said second body, selectively rotated relative to said second body and then compressed into said second body. claim 1 5. The apparatus as claimed in  claim 1  wherein said first connection means and said second connection means are selected from the group consisting of threaded connection, locking nut and compression flange. claim 1 6. The apparatus as claimed in  claim 1  wherein said third body is removed from said first body, permitting operation of said means for compressing to compress said hypodermic syringe to eject said radiopharmaceutical from the hypodermic syringe, while providing protection from said radiation. claim 1 7. The apparatus as claimed in  claim 1  wherein said hypodermic syringe is housed in an insert. claim 1 8. The apparatus as claimed in  claim 7  wherein said insert further comprises a first section and a second section wherein said second section is detachable from said first section. claim 7 9. An apparatus that acts as a shield for radiopharmaceuticals and protects individuals from radioactivity comprising: a) a first body with a first hollow core that is open on a first edge and a second edge of said first body, said first hollow core for housing a hypodermic syringe;  b) a second body with a second hollow core that is open on a first edge of said second body, said second hollow core for housing said hypodermic syringe;  c) a third body with a third hollow core that is open on a first edge of said third body, said third hollow core for housing said hypodermic syringe;  d) said hypodermic syringe capable of containing a radiopharmaceutical;  e) a first connection means wherein said first body releasably communicates with said second body for providing protection from radioactivity emitted by the radiopharmaceutical;  f) a second connection means wherein said first body releasably communicates with said third body for providing protection from said radioactivity;  g) said third body further comprising means for extending said hypodermic syringe from said first and third bodies to permit measurement of said radiopharmaceutical in said hypodermic syringe and providing protection from said radioactivity; and  h) said second body further comprising means for compressing said hypodermic syringe to eject said radiopharmaceutical from the hypodermic syringe while said first body is in communication with said second body. 10. The apparatus as claimed in  claim 9  wherein said first body, second body and third body are constructed from a plurality of radiation shielding materials. claim 9 11. The apparatus as claimed in  claim 9  wherein said means for extending comprises two rod connectors and means to securely fasten said rod connectors to said hypodermic syringe. claim 9 12. The apparatus as claimed in  claim 9  wherein said means for extending comprises a chain. claim 9 13. The apparatus as claimed in  claim 9  wherein said means for extending comprises a cable. claim 9 14. The apparatus as claimed in  claim 9  wherein said hypodermic syringe is housed in insert. claim 9 15. The apparatus as claimed in  claim 14  wherein said insert further comprises a first section and a second section, wherein said second section is detachable from said first section. claim 14 16. The apparatus as claimed in  claim 9  wherein said second body is removable from said first body allowing said radiopharmaceutical in said hypodermic syringe to be measured in a well counter. claim 9 17. The apparatus as claimed in  claim 9  wherein said third body is removable from said first body for said individual to manipulate said hypodermic syringe to inject a patient with said radiopharmaceuticals and be protected from said radiation. claim 9 18. The apparatus as claimed in  claim 9  wherein said means for compressing said hypodermic syringe comprises: claim 9 a) an internal sleeve, slidably and rotatably communicating with the interior surface of said second body and capable of partially extending outside of said second body through slots formed in said second body""s second edge;  b) at least one disk guide inside said second body and parallel to the long axis of said second body and extending the length of said second body;  c) an actuator cap fixedly attached to said internal sleeve and positioned to block said radiation emitted from the second edge of said second body, said actuator cap engaged by said at least one disk guide;  d) a disk having an at least one guide notch in slidable communication with said at least one disk guide such that the disk is prevented from rotating relative to said second body;  e) said disk further having at least one engagement notch;  f) at least one disk engagement tooth on the inside surface of said internal sleeve, said tooth positioned such that when the internal sleeve is selectively rotated to a position, said internal sleeve can be extended from and retracted into said second body without bringing said at least one engagement tooth into communication with the disk and when the internal sleeve is selectively rotated to any other position said at least one engagement tooth engages the disk when the actuator cap is compressed;  g) wherein said at least one engagement notch is sized slightly larger than said at least one engagement tooth.
