Studies of Radiation Effects in Three High Polymers
<p>Three high polymers, Mylar®, Ultem®, and Kapton®, were irradiated to total doses of 1, 5, and 9.5 gigarad using 1-MeV electrons. The glass transition temperatures (T<sub>g</sub>) of the materials before and after irradiation were measured using an AC electrical dissipation factor technique. From …

Direct and indirect effects of alpha-particle irradiations of human prostate tumor cells
… to the cell monolayer in the specially designed Mylar dish was calculated to be 1.2 Gy/min. In the biological part, three in vitro studies were carried out with the DU-145 human prostate tumor cells using the established alpha-particle irradiator. Firstly, the direct effects of the alpha-particle …
