DOE Core Radiological Control Technician (RCT) Practice Exam 2026 – Comprehensive Test Prep

Assessing what and where contamination exists before planning actions is the essential starting point. By surveying the area, you locate all contamination, measure its levels, identify its types (surface vs. fixed, removable vs. integrated), and establish boundaries and release criteria. This information is what dictates which decontamination methods are appropriate and how the work should be organized. Without it, plans could be misapplied, wastes mis-handled, or release criteria misjudged. Once the contamination is surveyed and classified, you can plan the decontamination methods, then perform cleaning or demolition to remove the contamination, and finally document release once the area meets the required criteria.
