Radiation Oncology/Physics/Photobiology


 * Photobiology is the study of the effects of ultraviolet, visible and infrared radiation on living organisms
 * It includes topics such as photosynthesis, vision, bioluminescence, circadian rhythms and photodynamic therapy
 * The field includes the study of photophysics, photochemistry, photosynthesis, photomorphogenesis, visual processing, circadian rhythms, photomovement, bioluminescence, and ultraviolet radiation effects
 * When photons come into contact with molecules, these molecules can absorb the energy in photons and become excited
 * Then they can react with molecules around them and stimulate "photochemical" and "photophysical" changes of molecular structures
