    • Analytical and rheological studies of modified gel dosimeters exposed to X-ray beams 

      Romero, Marcelo Ricardo; Mattea, Facundo; Vedelago, José; Chacón Obando, David M; Valente, Mariana A.; Alvarez, Cecilia; Strumia, Miriam Cristina (Elsevier Science, 2016-07)
      The need to know the dose of X-rays to be applied to patients suffering diseases such as cancer requires accurate and stable dosimetric devices. Currently, the use of gelatin-based dosimeters has yielded excellent results ...

    • Desarrollo de materiales poliméricos para dosimetría de rayos-x con sensibilidad óptica mejorada 

      Wolfel, Alexis; Chacón Obando, David M; Romero, Marcelo Ricardo; VALENTE, MAURO; Mattea, Facundo (Centro de Investigaciones en Laseres y Aplicaciones, 2020-10)
      En este trabajo se estudia el uso de un nuevo agente, capaz de formar complejos coloreados con iones metálicos, para su uso en dosimetría de Rayos-X (RX), con el objetivo de evaluar su efecto sobre la sensibilidad a la ...

    • Polymer gel dosimeter based on itaconic acid 

      Mattea, Facundo; Chacón, David; Vedelago, José; Valente, Mauro; Strumia, Miriam (2015-11)
      A new polymeric dosimeter based on itaconic acid and N, N'-methylenebisacrylamide was studied. The preparation method, compositions of monomer and crosslinking agent and the presence of oxygen in the dosimetric system were ...

    • Raman spectroscopy as a tool to evaluate oxygen effects on the response of polymer gel dosimetry 

      Chacón Obando, David M; Vedelago, J; Strumia, M.C; Valente, M; Mattea, F. (Elsevier, 2019-05-06)
      Currently, advanced dosimeters like polymer gels are capable of obtaining reliable and accurate 3D dose distributions from correlations with the different polymerization degrees induced by incident radiation. Samples of ...
