A far U.V. radiation source emitting high intensity of U.V. at wavelengths principally shorter than 2,000 A.U. includes an electric discharge in a low pressure of mercury vapor at a pressure 2x10<->3 to 0.1 torr and krypton gas at a pressure of approximately 0.5-10 torr. During operation, lamp current is very high, in range of 0.5 to 40 ampere/cm.2, emitting principally at a wavelength of 1,942 A.U.
