What action should be taken if a smear sample indicates contamination?

When a smear sample indicates contamination, the appropriate action is to evacuate the area and notify Radiological Protection (RP) personnel. This response is critical for ensuring the safety of all personnel in the vicinity and to initiate the proper contamination control protocols. Evacuating the area minimizes the risk of spreading contamination, which can have serious health and safety implications.

Notifying RP is essential as these professionals are trained to assess the situation, implement decontamination procedures, and mitigate any potential exposure to personnel and the environment. They have the expertise and resources necessary to handle such situations effectively.

The other actions outlined are not suitable responses. Continuing to work as usual could lead to unintentional spread of contamination, while documenting the findings without further action does not address the immediate risk posed by the contamination. Re-sampling in the same area does not resolve the contamination issue and may also risk additional exposure. Therefore, evacuating the area and contacting RP is the most responsible and safe course of action when faced with such findings.
