Grenz Rays

Oncologic Therapy

Grenz rays are a treatment using the lowest energy, ultrasoft part of the X-ray spectrum, first investigated by Gustav Bucky in 1923 using a cathode vacuum tube with a lithium borate glass window; he named them Grenz rays, German for border, because he believed their biological effects sat on the border between ultraviolet light and conventional X-rays, and they are also known as Bucky rays. They are produced by specially calibrated machines generally operating in the 10 to 30 kilovolt range, are absorbed by air, and so must be given at fixed distances for which the machine has been calibrated. In human tissue they penetrate only about half a millimeter and are essentially absorbed within the first two millimeters of skin, making them a treatment aimed at the skin's surface layers; their exact mechanism is unknown but they affect the Langerhans cells of the epidermis.

    These were first investigated by Gustav Bucky in 1923 using a cathode vacuum tube with a lithium borate glass window, which he labeled Grenz rays as he believed that the biological effects resembled those of UV light and traditional X-rays and hence were on the border between the two (Grenz = border in German).
