Precautions while using X Rays
Shielding should always be adequate
Shielding should always be adequate so other factors need not be required for safety. However, exposure reduction techniques include, increasing your distance from the x ray source, increasing shielding, and decreasing the time spent near the x ray source. Do not work near the open, unshielded beam. However, if it is necessary to work near the unshielded radiation beam (e.g., for system alignment): Reduce the beam current (mA) and the beam energy (kV) to the lowest settings possible to reduce exposure rates. Keep hands and body at a safe distance from the beam by using appropriate alignment tools.
