Radiation Protection
Radiation protection equipment
Personal shielding for diagnostic and interventional imaging: X-ray aprons, thyroid shields, leaded eyewear, gloves, mobile barriers and storage racks. Which products suit a given area depends on the procedures performed, how long staff spend near the field, and your facility's inspection and replacement policy — all of which your Radiation Safety Officer or medical physicist is best placed to advise on.
Protection level (lead equivalence)
Aprons are rated by lead-equivalent thickness in millimetres (mm Pb). As a rough orientation only, and not a recommendation:
- 0.25 mm Pb – often seen in lighter general radiography and lower-scatter settings; lightest to wear.
- 0.35 mm Pb – a common choice for fluoroscopy and OR imaging; a balance of attenuation and wearability.
- 0.50 mm Pb – sometimes used for high-scatter, long-duration interventional work; heaviest.
Front-protection aprons are lighter; full-wrap (front and back) aprons also cover staff who turn away from the field. A separate thyroid shield adds coverage that an apron collar does not.
Lead vs. lead-free
Lead-free and lightweight-composite aprons use antimony, bismuth, tungsten or tin blends to reach a given rated attenuation at less weight, which can matter for staff who wear an apron for long periods. They typically cost more, and published testing suggests their attenuation can vary somewhat with beam energy. Traditional lead-vinyl aprons are usually the lower-cost option where weight is less of a concern. Ask manufacturers for attenuation data across the energy range you actually use.
Fit, care and inspection
An apron that does not fit tends not to be worn. Common practice is to size to the wearer, use a support belt for heavier aprons, and store aprons on a rack rather than folded (folding is widely cited as a cause of shielding cracks). Many state health departments and accreditation bodies expect a documented apron-inspection program with defined acceptance criteria — your RSO or physicist sets the criteria that apply to you.
