Which of the following is NOT a requirement for radiographers before operating an exposure device?

Before operating an exposure device, radiographers must adhere to several safety protocols and requirements to ensure their safety and that of others around them. The requirement for radiation worker certification is an important aspect of a radiographer's training and ongoing practice but is not a specific equipment or tool required immediately before operating an exposure device.

The use of a survey meter is critical for measuring radiation levels in the environment, ensuring that the radiographer is aware of the surrounding radiation exposure before and during operations. Meanwhile, personal dosimeters like film badges and TLD pocket dosimeters help radiographers monitor their own radiation exposure over time, providing crucial data for maintaining safety standards. Additionally, emergency equipment is necessary to handle potential accidents or unexpected incidents during radiographic procedures.

Thus, while having the appropriate certification is essential for a radiographer's qualifications, it does not fall under the same category as the necessary equipment and tools required at the moment of operating an exposure device.
