Two procedures in protection radiology for Brachytherapy

Abstract:

Brachytherapy has aspects of Radiation Protection of special interest that are not given in the external radiotherapy. This is the case for the permanent implants with seeds of I-125 and for treatments with ophthalmic plates of Ru/Rh-106. The aim of this work is to show the performances fulfilled from Radioprotección Service of our hospital, establishing the similarities and the differences found in the application of every technology. Material and Methods: Seeds of I-125 Rapid Strand type 6711 given by Amershand Health. Ru-106 eyes Ophthalmic plates supported by Bebig. Dosimetric measurements were performed using TLDs, and chambers of several sizes. Results: Dosimetric measurements reflect that in the seeds load processes the dose in finger is far below of the legal limits applied to the public. In both cases, the sources implantation process does not suppose radiological risk, taking into account that the doses are below the limits applied to the public. The area dosimetry verifies that the remaining personnel (nurses, anaesthetists) can be treated as members of the public. Different recommendations are established in every case.
