“…Continuous x-rays emitted by nonrelativistic electron deceleration in an x-ray tube, i.e. bremsstrahlung, 11,12 was approximated by a blackbody radiation, 13,14 though the deceleration process of electrons in the solid metal target is more complex than the synchrotron radiation, and consequently a satisfactory agreement between the bremsstrahlung and the blackbody is not expected. Even a neutron, which has a charge distribution inside, can emit bremsstrahlung, and such 'atomic bremsstrahlung' is related to electromagnetic radiations from channeling, shock wave, earthquake, phase transition, friction and other exotic processes.…”

An Underappreciated Radiation Hazard from High Voltage Electrodes in Vacuum

et al. 2017

The use of high voltage (HV) electrodes in vacuum is commonplace in physics laboratories. In such systems, it has long been known that electron emission from an HV cathode can lead to bremsstrahlung x rays; indeed, this is the basic principle behind the operation of standard x-ray sources. However, in laboratory setups where x-ray production is not the goal and no electron source is deliberately introduced, field-emitted electrons accelerated by HV can produce x rays as an unintended hazardous byproduct. Both the level of hazard and the safe operating regimes for HV vacuum electrode systems are not widely appreciated, at least in university laboratories. A reinforced awareness of the radiation hazards associated with vacuum HV setups would be beneficial. The authors present a case study of a HV vacuum electrode device operated in a university atomic physics laboratory. They describe the characterization of the observed x-ray radiation, its relation to the observed leakage current in the device, the steps taken to contain and mitigate the radiation hazard, and suggested safety guidelines.
