In what scenario might a radiographer require gloves with 0.25 mm lead equivalency?

The need for gloves with 0.25 mm lead equivalency primarily arises during procedures where there is a potential for significant scattered radiation exposure. Scattered radiation can occur in various imaging modalities, particularly during fluoroscopic procedures where high-energy X-rays are utilized. The gloves serve as a barrier to limit exposure to the hands and prevent unnecessary radiation dose.

While other scenarios, such as handling radioactive materials, also require protective measures, the specific requirement for lead-equivalent gloves is most applicable in situations where scattered radiation is particularly high. This is because gloves can significantly reduce the risk of radiation exposure to critical areas, such as the hands, which are often closer to the radiation source during certain procedures.

In the context of the other choices: during fluoroscopy, while lead protection might be required for the radiographer as a whole, the specific mention of gloves with lead equivalency is not standard practice. For CT scans, although radiation dose is a concern, the scattered radiation levels do not typically necessitate lead gloves. Handling radioactive materials often involves different types of protective gear, focusing more on containment than on radiation shielding. Therefore, gloves with specified lead equivalency are most crucial for protecting against significant scattered radiation specifically encountered in certain radiographic procedures.
