Main property of x-radiation that makes it potentially hazardous is its ability to? - ANS - Ionize
Describe the damage potential of ionization? - ANS - Chain reaction in the human body that may
eventually cause biologic damage. X-rays are from the Electric Magnetic Spectrum or radiation
energy and is considered harmful in high energy ranges.
