Radiation source device having fluorescent material for secondary photon generation

A radiation source device, comprising:

• a shielding portion having a window portion cavity therein;
• a capsule portion housing the shielding portion;
• a radiolucent window portion extending across and encompassing the window portion cavity, a portion of the radiolucent window portion being positioned between the capsule portion and the shielding portion;
• a radioactive material positioned within the window portion cavity of the shielding portion to emit first photons through the window portion cavity and the radiolucent window portion;
• and
• a fluorescent alloy material in the window portion cavity coated onto the radioactive material and in contact with the radiolucent window portion and the shielding portion, the fluorescent material to generate second photons in response to receiving the first photons from the radioactive material.
