ATOMIC PHENOMENON EXPLAINING HOW γ-ray, β, and X-ray SUCCESSIVELY CAUSE BHARAT AND UV DOMINANT OPTICAL RADIATION EMISSIONS FROM WITHIN ONE AND THE SAME EXCITED ATOM IN RADIOISOTOPES AND XRF SOURCES.

A brief phenomenological explanation comprising of two postulates is described in the following, so that a detailed mathematical explanation can follow later.

(1) Ionizing radiation, particularly γ-, X-, or β radiation energy at keV or MeV level loses energy at eV level while passing through a core-Coulomb field. The loss of energy is reproduced as electromagnetic radiation with the same energy at eV level but higher than that of UV or EUV that the source emits.

(2) The energy causes valence excitation resulting into UV dominant atomic spectrum.

The phenomenon is explained here in simple terms, keeping in mind that a detailed mathematical explanation can follow based on detailed spectral studies in future. Suppose gamma, X-ray or beta radiation with energy E is passing through M shell Coulomb field in an excited atom of a radioisotope or XRF source. According to the phenomenon described in Fig. 6, the radiation loses energy only by a few eV, so escapes from excited atom with the rest of the energy E1. The loss of energy (E - E1) reappears as exciting energy (Bharat energy), EBR. The exciting energy EBR depends upon the initial ionizing radiation energy E, as explained already in the case of 57Co, and Rb XRF source.

E - E1 = EBR
