An electrostatic dissipation device 10 can comprise an elongated enclosure 11 with a longitudinal axis 12. An x-ray source 13 can be oriented to emit x-rays 16 inside of and along the longitudinal axis 12. A fluid-flow device 14 can be oriented to cause fluid to flow across the x-ray source 13 then inside of and along the longitudinal axis 12, the fluid being ionized by the x-rays 16, forming ionized fluid, then out of the elongated enclosure through outlet opening(s) 15. The arrangement of the x-ray source 13 and the fluid-flow device 14 can allow (1) fluid from the fluid-flow device 14 to cool the x-ray source 13, and (2) ion generation along the length of the elongated enclosure 11.
