GSR Part 3 Applicable Requirements Findings in Nuclear Medicine Modification

One of GSR Part 3 aspects that is addressed in several of its requirements is the treatment that, from the point of view of radiation safety, should be given to modifications that may have important consequences for protection and safety. The presentation shows, for a nuclear medicine department that performs bone and thyroid scans, and metabolic therapy, both, ambulatory and hospitalized with ¹³¹I, the justification analysis carried out of modification consisting in radioactive inventory increase (100% for technetium generator and 50% for ¹³¹I), maintaining reception frequency and staff participating in the benefits (Requirement 10). This modification arises at the request of clinical oncology service, as a result of positive impact that bone and thyroid gammagraphy has had on the diagnosis precision, follow-up and treatment of cancer patients, after around a year of work.
