RM, CM, and HRA on a survey map designate what categories?

RM, CM, and HRA on a survey map designate what categories?

• A. Radioactive material, Contaminated material, and High Radiation Area
• B. Radioactive material, Contaminated material, and Hazardous Radiation Area
• C. Radioactive material, Contaminated material, and High Radiation Zone
• D. Radioactive material, Contaminated material, and High Radiation Area

Answer: (D)

On a survey map these abbreviations flag three categories related to radiation safety: RM stands for Radioactive Material, indicating the presence or inventory of radioactive material; CM stands for Contaminated Material, meaning material that has become contaminated with radioactive material and may need decontamination or special handling; and HRA stands for High Radiation Area, which is a location where the radiation dose rate is high enough to require enhanced controls, restricted access, and monitoring. The term High Radiation Area is the standard designation, whereas “Hazardous Radiation Area” or “High Radiation Zone” aren’t the correct terms used in this context.
