5. The syringe shield according to claim 1 , wherein the removable cover ( 12 ) is configured to partially surround the barrel housing ( 6 ) so as to expose the underside ( 36 ) of the barrel housing ( 6 ) when the removable cover ( 12 ) is removably connected to the barrel housing ( 6 ), and wherein the underside ( 36 ) of the barrel housing ( 6 ) is shaped so as to prevent the barrel housing ( 6 ) from rolling when placed on a flat surface.
6. The syringe shield according to claim 5 , wherein the underside ( 36 ) of the barrel housing ( 6 ) is flat.
7. The syringe shield according to claim 1 , wherein the removable cover ( 12 ) is shaped so as to cover all surfaces of the barrel housing ( 6 ), except the underside ( 36 ) of the barrel housing ( 6 ) and the first open end ( 8 ), when the removable cover ( 12 ) is removably connected to the barrel housing ( 6 ).
8. The syringe shield according to claim 1 , wherein the removable cover ( 12 ) comprises a puck ( 38 ) which comprises a radiation shielding material, wherein the puck ( 38 ) covers the second open end ( 10 ) of the barrel housing ( 6 ) when the removable cover ( 12 ) is removably connected to the barrel housing ( 6 ).
9. The syringe shield according to claim 1 , wherein the removable cover ( 12 ) further comprises a handle ( 44 ).
10. The syringe shield according to claim 1 , wherein the removable cover ( 12 ) is shaped so that it is slidably mountable onto the barrel housing ( 6 ) by sliding the removable cover ( 12 ) in a direction from the second open end ( 10 ) towards the first open end ( 8 ).
11. The syringe shield according to claim 1 , wherein the removable cover ( 12 ) is shaped to receive a partially cylindrically shaped barrel housing ( 6 ) with a flat underside ( 36 ).
12. The syringe shield according to claim 1 , wherein the removable cover ( 12 ) is shaped as a partially cylindrical shell.
13. The syringe shield according to claim 1 , wherein the cover ( 12 ) is shaped so that said removable cover ( 12 ) can only be removed from the barrel housing ( 6 ) by sliding said removable cover ( 12 ) in a direction from the first open end ( 8 ) towards the second open end ( 10 ).
