Radio-fluorogenic Dosimetry with Violet Diode Laser-Induced Fluorescence

A set of experiments is described with radio-fluorogenic detectors and violet diode lasers. Radio-fluorogenic dosimetry is the measurement of absorbed dose by quantification of fluorescent products formed in response to ionizing radiation. Relative dosimetry was accomplished with 405nm violet diode laser-induced fluorescence (LIF) and digital imaging. Aqueous and gelatin-based solutions of radio-fluorogenic detectors were fabricated, irradiated with medical radiation devices, and pixel intensity values of digital images analyzed. The potential to use RFD to characterize spatial dose distributions with violet diode LIF is demonstrated.
