What must a worker submit if they require general access to a facility but do not normally perform radiological work?

In the context of workers requiring general access to a facility where radiological materials are handled, the appropriate protocol typically involves a monitoring program to ensure safety and compliance with regulations. A 28-day urine bioassay is a standard practice for monitoring potential exposure to radioactive substances for individuals who may encounter them during their routine activities, even if they do not regularly perform radiological work.

This bioassay is conducted at specified intervals to detect any radioactive material in the body that could be associated with exposure at the facility. The regulated timeframe allows for sufficient monitoring of potential internal contamination. Therefore, a 28-day urine bioassay is an optimal choice, as it strikes a balance between thoroughness in monitoring and the practicalities of workers who may occasionally enter areas where radiological work occurs without being part of the regular radiological workforce.

Other test options would either be too frequent or not align with the regulatory recommendations for non-radiological workers needing general access, thus making the 28-day urine bioassay the correct requirement for this situation.
