Abstract

The employment of Spectroradiometer experiments in optical radiometry and its precise calculus are very important for applied research, clinical trials, and companies that produce medical equipment. Thus, considering the concept of radiometry as an accurate energy measurement, this project aims to develop a laser, Leds, and lamps and carry out their characterization, with a view to developing a new methodology for calculation of the effective irradiance of biological systems; establishing and implementing protocols for accurate measurement of laser and leds systems in FFCLRP (Faculdade de Filosofia, Ciências e Letras de Ribeirão Predto), FORP (Faculdade de Odontologia de Ribeirão Preto), and FCFRP (Faculdade de Ciências Farmacêuticas de Ribeirão Preto); carrying out personal dosimetry of ultraviolet and infrared radiation in the Ribeirão Preto campus (USP/RP) in partnership with SESMT (Serviço de Engenharia, Segurança e Medicina do Trabalho), and finally setting up the Optical Dosimetry Laboratory to support the productive sector of the Ribeirao Preto city and USP scientific community. To reach these goals the Optical Dosimetry Laboratory will be equipped with calibrated detectors, Spectroradiometer, and knife-edge systems that will allow for experimental acquisition of all the variables that are necessary for determination of the radiometric parameter for different emission sources (lasers, LEDs, lamps, or composed systems) applied for different irradiation conditions (biological samples, cell culture, or personal dosimetry). The importance of an Optical Dosimetry Laboratory for the scientific community and the productive sector are evident. The research work conducted in our Group and coordinated by me covers the applied research, instrumentation, collaboration with other research areas, and personal dosimetry of non-ionizing radiation. It will be possible to better evaluate the generated publications at the end of this project, where our experience in optical dosimetry and radiometry will be highlighted. (AU)
