To investigate the effects of ionizing radiation on polymeric materials commonly used in fused deposition modeling (FDM) 3D printing, evaluating structural stability, mechanical behavior, and potential microstructural changes following exposure to different i...

The simultaneous production of iodine-125 (¹²⁵I) and iodine-126 (¹²⁶I) during neutron irradiation directly impacts radionuclidic purity and clinical applicability of brachytherapy seeds. This study evaluated the dependence of ¹²⁵I and ¹²⁶I generation on irrad...

Radiosynovectomy (RSV) is a minimally invasive therapeutic option for the treatment of chronic synovitis, with yttrium-90 (⁹⁰Y) being particularly suitable for large joints such as the knee. In Brazil, national production of therapeutic radiopharmaceuticals r...
