In a field setting using a 300 kV x-ray system, what minimum boundaries must be established?

In a field setting utilizing a 300 kV x-ray system, it is essential to establish boundaries that reflect the potential hazards associated with radiation exposure. The correct choice, which highlights the need for both high radiation areas and radiation areas, is crucial for ensuring safety around x-ray systems.

High radiation areas are defined as locations where individuals could receive a radiation dose of 0.1 rem (1 mSv) or more in an hour at 30 cm from the source of radiation. These areas require stringent controls and access restrictions to protect personnel from excessive exposure. In contrast, a radiation area is one where the radiation levels are below the high radiation threshold but still warrant caution and awareness. This distinction aids in properly delineating the zones based on their specific radiation levels, ensuring that appropriate safety protocols are followed.

By establishing these clearly defined boundaries, operators can ensure that safety measures are implemented, such as signage, barriers, and access controls, to minimize the risk of unintentional exposure. Such measures align with regulatory requirements for radiation safety and help create a structured approach to managing the risks associated with high-energy x-ray radiation.
