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 Photophysics Photochemistry
