Safe Handling and Disposal Of Radioactive Materials

The personnel working in the nuclear medicine clinics and research laboratories are exposed to radiation in their normal working environment. To reduce the harmful effects of radiation like damage to cells and damages to chromosomes, there should be proper safe handling and disposal of radioactive materials. The first safety is ALARA Concept “As Low as Reasonably Achievable” which means making every reasonable effort to maintain exposures to ionizing radiation as far below the dose limits as practical. For the safety purpose, the personnel can spend as little time in hot labs and high level radiation areas, labs should not be used for visiting, discussing, unrelated activities in the area, and monitors should be used to warn personnel when radiation sources are present. The laboratory should be located away from other work areas, public corridors, offices etc., work surfaces and floors- smooth, non-absorbent materials and free from cracks, workbenches – sturdy to support lead shielding, washbasins and sinks – conveniently available, and separate storages for glass wares and work tools. The radioactive disposal wastes containing short lived radioactive isotopes must be released into municipal dumbs.

Solid waste of larger activity can be disposed by burial provided a suitable isolated area. Survey Meters are also used to monitor radiation levels in and near laboratories where radioactive materials are present. Wipe test is done to detect small amount of radioactive contamination on bench top surface or outside of shipping package or small amount of leakage. The surface is wiped with an alcohol soaked patch of gauze or cotton tipped swap which is then counted in a well counted.
