Development and Characterization of Silver Containing Free Standing Polymer FILMS for Dosimetry Applications

Polymer gels and films, due to their near equivalence to biological tissue, are amongst the most promising future dosimetry tools for medical applications. The application of polymer dose gels is limited by the sensitivity of dose readout methods and dose gel properties. It is a challenge to find su...
