FIG. 1: First and definite experimental evidence for UV dominant optical spectra of Rb XRF source, metal 57 Co source (notably at room temperature), 137 Cs, and 60 Co from peak intensity  measure-ments made with narrow band optical filters at 330, 350, 365
TABLE I. UV dominant optical emission from (1) Rb and Ba XRF sources, (2) radiochemicals such as 113 Sn, and (3) metal 57 Co is evident from the columns on %UV, %VIS, and
FIG. 3: The three plots (a, b, and c) made from spectral data of Ta- Ta-ble I disclose existence of a linear relation between ionizing  radia-tion energy and the percent UV, VIS, and NIR radiaradia-tion intensities in the gross light intensity
FIG. 5: Schematic of known Rb X-ray spectrum from Rb excited atom of Rb XRF source is shown on the left
