TYPES OF RADIATION

Radiation in Space Ionizing Radiation There are several forms of ionizing radiation in space. Ionizing radiation deposits energy onto the atoms and molecules with which it interacts, causing electrons to be lost. The resulting ions, or charged particles, give this form of radiation its name. One form of ionizing radiation is galactic cosmic

Ionizing radiation may affect normal tissues through direct cellular (e.g., clonogenic cell death, apoptotic cell death), direct functional (e.g., point mutations), and indirect injury processes [6]. However, most of the detrimental effects of ionizing radiation in biological systems occur mainly due to its indirect effects. Upon exposure to

Studies comparing MR en-terography with small bowel follow-through have shown that the modalities are equally accurate, although MR enterography is significantly more sensitive (14,28). The increased sensitivity of MR enterography is seen in the detection of the extraenteric manifestations and penetrating com-plications of IBD.

1.1.1. Ionizing Radiation for Cancer Treatment Radiation is the transmission of energy through space and matter (1). Ionizing radiation, such as x rays, has sufficient energy to eject an electron from an atom. The atom becomes electrically charged or ionized. In biologic matter, the dislodged electrons from ionized atoms can interact
