Final answer:
Radiographers may be required to wear two dosimeters during pregnancy, while performing vascular procedures, and while performing mobile radiography.
Step-by-step explanation:
A radiographer might be required to wear two dosimeters under certain circumstances.
1. During pregnancy, it is important for a radiographer to monitor their radiation exposure closely to ensure the safety of both the mother and the developing fetus. Wearing two dosimeters can provide a more accurate measurement of radiation exposure.
2. While performing vascular procedures, a radiographer may be exposed to higher levels of radiation due to the use of fluoroscopy. Wearing two dosimeters can help assess the radiation exposure from different angles and positions.
3. While performing mobile radiography, a radiographer may encounter varying radiation levels depending on the distance and shielding. Wearing two dosimeters can help determine the radiation exposure in different locations.
