The idea being tested is a planned, systematic approach to removing contamination so exposure is kept as low as reasonably achievable during entry and reconnaissance operations. This describes technical decon: a defined set of steps, monitoring, and controls used to actively remove contaminants from responders and equipment in a way that protects people and allows entry to continue safely.

Technical decon is designed to be thorough and verifiable. It follows a sequence—often starting after initial field or gross decon—to ensure residual contamination is reduced to acceptable levels before responders continue operating or leaving the hot zone. This focus on deliberate removal and verification, all aimed at minimizing exposure while enabling necessary operations, is what makes it the best choice.

Other approaches don’t fit this description. Absorption is just soaking up liquid contamination and doesn’t constitute a complete, planned decon process. Dilution reduces concentration but isn’t a formal decontamination method aimed at returning people or gear to safe levels. Blanketing involves covering or surrounding material to control spread, not systematically decontaminating to ALARA.
