Analysis of the depolarizing properties of irradiated pig skin

Abstract

Further to the irradiation of pig with cobalt, the polarimetric properties of skin samples were experimentally investigated, and the Mueller matrices were measured at different wavelengths. Whatever the studied sample, both increase of irradiation rate and reduction of wavelengths decreased the depolarization. Finally, we demonstrate that, 70 days after irradiation, polarization measurements allow one to distinguish a healthy pig skin sample from a 15 Gy- or 20 Gy-irradiated one.
