What is the purpose of the exit portal contamination monitor?

The purpose of the exit portal contamination monitor is to check for radioactive contamination. These monitors are crucial for ensuring the safety of personnel as they leave controlled areas where radioactive materials may be present. By detecting and measuring any contamination that may have inadvertently been brought out on personnel or their belongings, these monitors help prevent the spread of contamination into unrestricted areas.

This function is an essential part of radiation safety protocols and helps protect both workers and the public from potential exposure to radioactive materials. Effective monitoring at exit points serves as a critical control measure in maintaining radiological safety standards and ensuring compliance with regulatory requirements. It reflects a proactive approach to managing safety and mitigating risks associated with handling radioactive substances.
