According to Texas Regulations, what is the required operating range of a pocket dosimeter for industrial radiographers?

The required operating range of a pocket dosimeter for industrial radiographers, as specified by Texas Regulations, is indeed from 0 to 200 mR/hr. This range is designed to ensure that radiographers can accurately measure and monitor radiation exposure levels in environments where radiographic testing is conducted, which typically involve significant exposure to ionizing radiation.

The choice of 200 mR/hr not only allows for effective readings in the normal operating conditions of industrial radiography but also accommodates unexpected peaks in radiation levels that could occur during operations. It ensures that workers can receive timely indications of their exposure so they can take necessary actions to minimize risk and remain safe.

The other options present ranges either too low or too high for effective monitoring in this specific field. A lower range might not capture the necessary levels of exposure found in industrial settings, while a higher range might not provide the precision needed to reflect the actual radiation levels encountered in typical use. Thus, the 0 to 200 mR/hr range is optimal for the operational needs and safety of radiographers.
