Tried to use "Google labs: Books Ngram Viewer" for the words related to my past activities:
•Dosimetry vs irradiation —I made researches related to these words just in the years when these showed peaks.
•Betatron vs linac —I worked with an electron linac around the years of the first peak of the linac.
•Electron backscatter vs ion reflection —I studied the former in the years around its first peak; the latter, just during the years of its peak.
