In plain language
This US medical physics guideline recommends cumulative air kerma for patient dose alerts (first at 3 Gy, then every 1 Gy), follow-up above 5 Gy, and single collar-badge monitoring with lens dose assessment for the fluoroscopy team.

What it found
Cumulative air kerma (Ka,r) is recommended as the primary dose index for setting notification and patient follow-up thresholds.
Consensus intra-procedural notification levels start at 3 Gy Ka,r, with further notifications every 1 Gy Ka,r.
Key figures: first at 3 Gy Ka,r; every 1 Gy thereafter
Suggested SRDL for post-procedure patient follow-up is 5 Gy Ka,r or 3 Gy PSD, with doses summed over a 60-day window.
Key figures: 5 Gy Ka,r or 3 Gy PSD; 60 days
A single collar badge with personal protective equipment (PPE) correction is recommended for fluoroscopically guided interventional (FGI) staff because double badging is often misused; over a third of two-badge entries were invalid in a large review.
Key figures: over a third of entries invalid
Lens dose should be assessed; a prior large study found over 15% of workers exceeded the International Commission on Radiological Protection (ICRP) 20 mSv/year lens limit.
Key figures: over 15%; 20 mSv/year
Limits to keep in mind
Consensus practice guideline based on expert opinion and cited literature rather than new data; it focuses mainly on patient tissue reactions, with occupational monitoring covered only briefly.
