Clearing the working area
All materials that cannot be reused (such as used syringes, opened vials of 0.9% saline solution and any other used or opened disposable materials) and could be contaminated with radioactivity must be discarded in the radioactive waste bin. The absorbing paper that was used in the working area should also be discarded in the radioactive waste bin. Ideally radioactive waste is separated into radioactive sharps and radioactive non-sharps. Non-radioactive waste is discarded in a non-radioactive waste bin.
All instruments that will be used again in other preparations (such as tongs, forceps, syringe shields and lead vial shields) must be checked for radioactive contamination using a radiation detector. If no contamination is detected, these items should be stored in an appropriate place ready for the next preparation. If the instruments are contaminated, they can be stored in a shielded place until the radioactivity has decayed sufficiently, or they can be decontaminated, for example, by soaking them in a bath of decontaminating solution.
The working area and the walls of the LAF cabinet are then checked for contamination with radioactivity using a radiation detector.
