Which decontamination method is typically considered the last resort?

The decontamination method typically considered the last resort is the technical method. This approach is often used when other decontamination methods are insufficient to clean surfaces or equipment effectively. Technical decontamination focuses on specialized techniques and equipment that go beyond standard practices, often involving complex procedures such as the use of robotic systems, specialized chemicals, or containment strategies to manage particularly hazardous materials.

Technical methods are reserved for extreme cases where conventional approaches like absorption or shower systems may not adequately address the contamination. These methods can be resource-intensive and time-consuming, requiring careful planning and execution to ensure safety and effectiveness.

In contrast, absorption, shower systems, and degradation methods are usually applied first or in conjunction with other decontamination efforts, as they are more straightforward and can be implemented quickly to reduce contamination levels efficiently.
