Development of a model for registration and notification of accidents and incidents in nuclear medicine.

Nuclear medicine (NM) is a medical speciality that uses unsealed radioactive sources involving several handling procedures with some critical points before, during, and after the examination and therapies performed, requiring special attention to the occurrence of a possible accident or incident over the course of the clinical routine. The accidents and incidents in NM can involve actors such as workers, patients, the public or caregivers, and even the environment. Although expected, the number of occurrences and their nature are not well understood due to the absence of a Brazilian reporting tool for incidents or accidents.
