Blood irradiation therapy
（重定向自Ultraviolet blood irradiation）
Blood irradiation therapy is a procedure in which the blood is exposed to low level red light (often laser light) for therapeutic reasons. Most research on blood irradiation therapy has been conducted in Germany, Russia and China, while smaller-scale research has been performed in other countries such as Britain. Blood irradiation therapy can be administered through a catheter in a vein, through the blood vessels inside the nose or applied externally through the skin. It is not related to the practice of gamma irradiation of blood in transfusion medicine.
