Shielding degrades over time — lead can crack where aprons are folded, seams separate, closures fail. Many state radiation-control programs and accreditation bodies expect facilities to run a documented apron-inspection program. What that program must contain, and the criteria it uses, are set by your Radiation Safety Officer or medical physicist and by the rules that apply to you — this article only describes how such programs are commonly structured.
What is commonly expected
Expectations vary by jurisdiction, but a frequently seen baseline is: visual and tactile inspection on receipt and periodically thereafter (annually is common); fluoroscopic or radiographic inspection at defined intervals; written acceptance and reject criteria; and a log. Accreditation surveys often ask to see the log and the criteria. Confirm the actual requirements with your RSO and state program.
Inspection methods commonly used
- Visual — the apron is laid flat under good light and checked for surface cracks, stiff or brittle areas, and closure damage.
- Tactile — the whole surface is felt by hand for gaps, lumps or thin spots.
- Fluoroscopic / radiographic — the apron is imaged (low mA); defects show as bright spots or lines.
Acceptance and reject criteria
Some published guidance (for example certain AAMP/AAPM materials and individual state programs) cites conventions such as: rejecting any defect in the region covering reproductive organs, sternum and thyroid; and thresholds for defect area elsewhere. These are conventions cited in some sources, not a universal standard. Use only the acceptance and reject criteria approved by your own RSO or physicist.
Care practices that are commonly recommended
- Do not fold aprons. Hanging on an apron rack or laying flat is widely recommended; folding is frequently cited as a cause of premature cracking.
- Clean per the manufacturer's guidance — typically a damp cloth and mild disinfectant, not soaking or machine washing.
- If a rack is not available, transporting rolled loosely rather than folded is the common advice.
- Assigning each apron a unique ID makes a fleet trackable.
Retirement
Aprons that fail inspection are typically removed from service and tagged so they are not returned to use. Lead and lead-composite aprons are generally treated as hazardous waste — a licensed disposal vendor and a retained manifest are the usual approach. Lead-free aprons can often go to standard waste; confirm with the manufacturer and your EHS team.
A starting point for discussion with your RSO
- Does every apron have a unique ID and an inspection record?
- What inspection intervals and methods does our physicist require?
- Whose acceptance/reject criteria are we using, and are they documented and approved?
- Is there a rack in every location where aprons are stored?
- How are failed aprons tagged, removed and dispositioned?
- Is replacement planned on a rolling cycle or handled reactively?
We can supply aprons, apron racks for every storage point, and help plan a rolling replacement cycle. Ask us about a supply review.
