Although limited information is available on the effects of different types of radiation on the symptoms of dermatomyositis, evidence has suggested that autoimmune diseases (such as dermatomyositis) result from environmental exposures in genetically susceptible individuals. Ultraviolet (UV) radiation is associated with increases in conditions characterized by photosensitive rashes, including dermatomyositis. How UV radiation might specifically affect the various symptoms of dermatomyositis is unknown. It is also not known whether other types of radiation might affect the severity or duration of symptoms of the condition.
