Radiography is the making of records of internal structures of the body by passage of x-
+j +j +j +j +j +j +j +j +j +j +j +j +j +j +j
rays or gamma rays through the body. These records or images are typically referred to as r

Some forms of electromagnetic energy, including x-
+j +j +j +j +j +j
rays, have the ability to ionize atoms in matter. These ionizations have the ability to disrupt
+j +j +j +j +j +j +j +j +j +j +j +j +j +j +j +
the composition of matter and are capable of disrupting life processes. Special protection s

Radiography involves the use of x- +j +j +j +j +j
rays for the production of medical images. Medical procedures such as thermograms, sonog

The Hippocratic Corpus is writings that they emphasize rational and natural explanations for
+j +j +j +j +j +j +j +j +j +j +j +j
the treatment of disease and reject sorcery and magic. The Hippocratic oath still governs t

a variety of hereditary diseases, and through genetic engineering, important pharmaceutica
