What must be done before decontaminating a person exposed to radioactive materials?

Before decontaminating a person exposed to radioactive materials, it is essential to assess their level of contamination and health status. This step is crucial because it allows responders to understand the extent of the contamination on the individual and determine if there are any immediate health concerns that need to be addressed before decontamination occurs.

Assessing contamination involves checking for radioactive particles externally and internally, as well as evaluating the physical condition of the person. If the individual is injured, unconscious, or unable to move, immediate medical assistance may be necessary prior to or during decontamination. Understanding both the level of contamination and any potential health risks can ensure a more effective and safe decontamination process, protecting both the affected individual and the responders.

Taking any action without assessing could compromise safety and health, potentially leading to inadequate treatment or further spread of contamination. Hence, accurately evaluating the situation is not just a procedural step but a key measure to ensure appropriate intervention and care.
