What is one reason for using a collar and waist method for monitoring exposure in pregnant radiographers?

Using a collar and waist method for monitoring exposure in pregnant radiographers primarily ensures accurate readings of radiation exposure. This method places the monitoring devices at strategic locations on the body. The collar is positioned at the level of the head or neck, while the waist badge is placed lower on the body.

Radiation exposure may vary based on the location on the body due to factors such as proximity to the radiation source and shielding. By using both a collar and waist badge, the monitoring system can more accurately reflect the amount of radiation exposure that the radiographer receives during their work. It allows for a comprehensive assessment of exposure that takes into account the differences in radiation levels at different heights and body regions, which is particularly important for pregnant radiographers to ensure the health and safety of both the individual and the developing fetus. This approach helps in making informed decisions regarding exposure limits and protective measures throughout their pregnancy.
