Abstract: A novel, VOC-free-renewable solid-state biopolymer detector is presented for applications pertaining to mid-to-extreme gamma-electron beam dosimetry applications. Polylactic-Acid (PLA) based “green” biopolymer was used to derive PLAD – a renewable, inexpensive solid-state radiation detector that promises to offer significant potential benefits over when compared with state-of-art detectors for detecting gamma-electron and also other forms of ionizing radiation. Experimental data are presented on well-correlated measurements of ionizing radiation in the mid-to- extreme dose range to readily discernible physical property changes such as relative viscosity, embrittlement, and molecular bonding.


Keywords: Polylactic Acid, PLA, Radiation, Gamma, Electron, FTIR, Detector, Dose.
