Radiography is the making of records of internal structures of the body by passage of x-

rays or gamma rays through the body. These records or images are typically referred to as

ANS: A nznz
Some forms of electromagnetic energy, including x-

rays, have the ability to ionize atoms in matter. These ionizations have the ability to disrup

t the composition of matter and are capable of disrupting life processes. Special protectio

diagnostic modalities. A few of these involve the use of ionizing energy to create a medic

Radiography involves the use of x- nz nz nz nz nz
rays for the production of medical images. Medical procedures such as thermograms, sono

grams, and magnetic resonance scans use nonionizing energy forms and consequently do n

ot produce ionizations in human tissue. They are regarded as nonionizing modalities for im

aging and offer excellent alternatives to physicians concerned about radiation exposure to
