In the 1920's Millikan also began an increasingly intensive program of research into the penetrating radiation which in mid-decade he would name "cosmic rays." In 1912 the Austrian-born physicist Victor Hess had found that atmospheric ionization increased with altitude up to 12,000 feet. But although Hess had argued that some kind of radiation was coming from the heavens, most physicists still attributed the phenomenon to some terrestrial cause, such as electrical discharges from thunderstorms or radioactivity. Millikan's initial experiments in the field, done with an unmanned sounding balloon in 1922 to a height of fifteen kilometers and with lead-schielded electroscopes atop Pike's Peak in 1923, failed to decide in favor of either interpretation. In the summer of 1925 Millikan proposed to settle the question by measuring the variation of ionization with depth in Muir Lake and Lake Arrowhead in the mountains of California. Snow-fed and separated by many miles, as well as 6,675 feet of atmosphere, each was likely to be free of both local radioactive disturbances and whatever atmospheric peculiarities might affect the ionization in the other. Millikan's electroscopic measurements showed that the intensity of ionization at any given depth in lake Arrowhead was the same as the intensity six feet lower in Muir Lake. Since the layer of atmosphere between in surfaces of the two lakes had precisely the absorptive power of six feet of water, the results decisively confirmed that the radiation was coming from cosmos. Moreover, since the intensity of the ionization showed no diurnal variation, the radiation was uniformly distributed over all directions in space. And, Finally, since Millikan detected ionization as far below the top of the atmosphere as the combined air and water equivalent of six feet of lead, it was evident that cosmic rays were a good deal more energetic than even the hardest known gamma rays. (DSB Vol. 9, pp. 397-398). The Nobel Prize in Physics 1923 was awarded to Robert A. Millikan "for his work on the elementary charge of electricity and on the photoelectric effect".
