In radiation shielding, a primary barrier is designed to protect against what?

Explanation:
Primary shields are placed directly in the path of the x-ray tube’s main output to protect people who may work in the area. They’re designed to attenuate the full-intensity primary beam so occupational exposure stays within limits. Scatter and leakage are handled mainly by secondary barriers, not by the primary barrier, and exterior environmental radiation or heat transfer aren’t the primary purposes of a primary shield. So the correct idea is that the primary barrier protects against the direct beam.
