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


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

ANS: A njnj


Some forms of electromagnetic energy, including x-

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

he composition of matter and are capable of disrupting life processes. Special protection sh

ould be provided to prevent excessive exposure to ionizing radiation.

ANS: B njnj


The Hippocratic Corpus is writings that they emphasize rational and natural explanations for

the treatment of disease and reject sorcery and magic. The Hippocratic oath still governs the

ethical conduct of physicians today.

6. Wilhelm C. Roentgen’s discovery of ―the x- nj nj nj nj nj nj


ray‖ is regarded as one of medicine’s most significant achievements. Although his discove

ry was accidental, his early research was so thorough that no significant findings have bee

n added to his original theories. This in itself is a true tribute to the brilliance of Roentgen
nj nj nj nj nj nj nj nj nj nj nj nj nj nj nj nj nj nj


as a scientist. One of the most famous early images he created was an x-ray image of his
