Which of the following is NOT a criterion for a "declared pregnant" female radiation worker to inform her employer of her pregnancy?

A "declared pregnant" female radiation worker is one who has voluntarily informed her employer of her pregnancy, which is crucial for the protection of both the worker and the developing fetus. Understanding the key criteria that necessitate this declaration is important for compliance with workplace safety regulations regarding radiation exposure.

The criteria for a pregnant radiation worker to inform her employer include voluntarily deciding to make the declaration, doing so in writing to create an official record, and typically being based on a confirmed state of pregnancy, such as a positive HCG test. These steps help ensure that appropriate measures can be taken to manage the worker's exposure to radiation effectively.

Knowing the estimated due date of delivery is not a required criterion for declaring a pregnancy to an employer. While it may be helpful information for planning and risk management, it is not a formal prerequisite in the declaration process. Therefore, understanding these components underscores the importance of communication and safety measures within radiation-related work environments while clarifying what is mandated versus what is simply beneficial to know.
