A licensed X-ray employer must

• A. take all precautions necessary to provide protection to all individuals exposed to radiation
• B. limit staffing to reduce exposure
• C. avoid using dosimeters
• D. allow untrained personnel to operate equipment

Answer: (A)

Protecting everyone who could be exposed to radiation is the fundamental obligation of a licensed X-ray employer. This means implementing every prudent protective measure to minimize exposure for patients, staff, and others who might be near the imaging area. The best choice captures this duty by stating that the employer must take all precautions to provide protection to all individuals exposed to radiation, aligning with the ALARA principle and regulatory expectations.

The other ideas don’t meet that responsibility. Merely limiting staffing to cut exposure doesn’t address how to systematically protect people and can undermine care and safety. Avoiding dosimeters would leave occupational exposure unmonitored and noncompliant with safety standards. Allowing untrained personnel to operate equipment violates required training and supervision, compromising safe operation and shielding practices.
