Student's Guide

c. Radiological Areas

There are radiological areas established within the controlled area.

"Radiation Area, High Radiation Area, and Very High Radiation

Area," identify areas where the hazard is exposure to ionizing

radiation and the different areas designate increasing levels of

hazard (increasing levels of dose rates).

"Contamination Area" and "High Contamination Area" identify

areas where the hazard is from accessible loose radioactive

contamination. Protective clothing is used to prevent

contamination of personnel.

"Airborne Radioactivity Area" indicates the potential for radioactive

contamination in the air. Protective clothing and respiratory

protection may be used to protect personnel from inhaling the

contamination or getting contamination on their skin."

This training typically will NOT permit you to enter these areas.

Personnel trained at the GERT level are typically not permitted to

enter these areas unless escorted and/or trained.

d. Radiological Buffer Area

1) A radiological buffer area may be established within the

controlled area to provide a secondary boundary for minimizing

exposures to radiation or contamination.
