Low Energy X-rays
Greetings all,
On the low end of the energy spectrum, at what kVp would you start being
concerned about x-ray exposure? I've been trying to find HVLs for extremely
low energy x-rays and have been unsuccessful. I mean, hydrogen ionizes at
13.6 eV, but survey meters are only sensitive down to around 8 keV. How do
you do heath physics below that energy? Sheet rock seems to be an adequate
shielding for dental x-ray energies (considering their short exposure times)
but what about a steady state field of 10 kVp x-rays where you can't add
extra shielding? Where's the 5 mR/hr line?
Any help would be appreciated. Thank you in advance.
