WebIonising radiation also includes X-rays and UV rays. We cannot receive too many X-rays over the course of a lifetime as this is a cancer risk. UV from sunlight also has the potential to damage cells and cause cancer. Broadly speaking, this area of the electromagnetic spectrum is the most dangerous. So what about non-ionising radiation? WebDigital radiography is a type of X-ray imaging that uses digital X-ray sensors to replace traditional photographic X-ray film, producing enhanced computer images of teeth, gums, and other oral structures and conditions. Digital dental images are acquired through three methods: the direct method, indirect method and semi-indirect method. WebJan 8, 2016 · X-rays were shown to cause biological effects shortly after their discovery by Wilhelm Conrad Roentgen in 1895. In fact, the early researchers often estimated the radiation output of their X-ray tubes by exposing a patch of skin.
