Hand Held X-ray Devices

Emil Grubbe (1875-1960) learned the hard way about handheld X-ray devices. A month after Roentgen first reported the existence of X-rays in 1895, Grubbe used a Crookes tube to irradiate a woman’s breast tumor, having seen the burning effect radiation had on his own hand. Over many years, radiation burns caused him to lose all his fingers. The problem was that he had no way to
“tune” the direction of the X-rays so as to focus on the tumor. But now, researchers in Singapore and at MIT have shown how a sheet of graphene can do was Grubbe was unable to do—tune radiation in a small device. MORE
