A recently completed systematic review explores published evidence on whether irradiation of platelets affects their quality, effectiveness and safety. The available evidence made answering this question difficult, however we concluded that “overall, gamma irradiation has little to no effect on most markers of platelet quality and effectiveness” and “there is very limited evidence for x-ray as a source of irradiation”.
