grenz ray

(grenz), Although in German spelling Grenz, like all nouns, begins with a capital letter, its English derivative is spelled with a lowercase g.
Very soft x-rays, closely allied to the ultraviolet rays in their wavelength (that is, relatively long) and in their biologic action upon tissues; they are produced by a specially built vacuum tube with a hot cathode operating from a transformer delivering not more than 8 kw.
[Ger. Grenze, borderline, boundary]

grenz ray

A low-energy x-ray photon with an average wavelength of 2 A.U. (range from 1 to 3 A.U.); obtained with peak voltage of less than 10 kV. Grenz rays lie between ultraviolet and x-rays.
