IRMER 2017 relates to what safety context?

• A. Ionising radiation risk management for staff.
• B. Regulatory framework for dental impressions.
• C. Protocol for infection control.
• D. Protection of patients from ionising radiation during medical imaging.

Answer: (D)

The key idea here is protecting patients from exposure to ionising radiation during medical imaging. IRMER 2017 sets the requirements for how imaging procedures are justified and delivered to patients, with the aim of keeping doses as low as reasonably practicable while still achieving a diagnostic outcome. In practice, this means every radiographic exposure must be clinically justified, the technique optimised, and quality assurance and appropriate staff training in place. In a dental setting, this directly applies to radiographs such as bitewings, panoramics, and periapicals, where the goal is to obtain the necessary diagnostic information with the smallest possible radiation dose. The other areas mentioned—regulatory rules for dental impressions or general infection control—are not about shielding patients from ionising radiation during imaging, and staff radiation safety is covered by separate regulations.
