Grenz rays are x-rays produced at low kilovoltages in the 5-20 kev energy range, giving them a very low penetration power. They have been used medically since the 1920s and used to be an important treatment for skin disorders. Their popularity declined with the creation of easier to administer treatments such as cortisone creams.

There are no mainstream peer-reviewed medical papers that have confirmed the effectiveness of Grenz Rays.
