Free radicals inhibitor effect on makrofol E nuclear tracks. Preliminary data

Thin foils of Makrofol E prepared with and without inclusion of a free radical scavenger (DPPH), were irradiated at the Tandar facilities. 374 keV and 50 keV ¹⁶O⁺⁺ ions from a Varian Ion Implanter and ⁷Li⁺ ions at different energies from a Tandem accelerator were used. Replicas of the etched foils were observed by transmission electron microscopy.

Track 3iameters exhibited a slight difference between the treated and untreated foils in the case of irradiation with ¹⁶O ions. A larger difference between the groups in the case of ⁷Li ions was found.
