Under what condition is a radiographer required to wear two dosimeters?

A radiographer is required to wear two dosimeters during pregnancy to ensure comprehensive monitoring of radiation exposure. This practice is in place because the primary dosimeter is typically worn at the worker's waist, which may not accurately reflect the exposure received by the developing fetus. By wearing a second dosimeter at the collar or on the chest area, it allows for more precise tracking of the radiation dose that could potentially affect the fetus, providing important data for evaluating safety and making informed decisions regarding occupational exposure.

This requirement emphasizes the importance of protecting both the radiographer and any potential vulnerable populations, such as unborn children, from unnecessary radiation exposure during pregnancy.
