What radiation protection equipment does a hospital department need?
Most departments combine three layers: personal protection, procedure-side protection and management. Personal protection means protective aprons or two-piece garments, thyroid collars and protective eyewear for anyone who stays in the room during exposures. Procedure-side protection means table-mounted shields and mobile barriers that reduce scatter before it reaches staff. Management means proper hanging storage, regular inspection and a replacement plan.
The specification for each layer, including lead equivalence, comes from a radiation risk assessment carried out with your Radiation Protection Adviser.
What radiation protection is used in interventional radiology?
Interventional teams typically wear a protective apron or top-and-kilt set, a thyroid collar and protective glasses, and work behind table-mounted shields and mobile barriers. IR involves prolonged fluoroscopy close to the patient, so scatter dose to staff is higher than in general radiography. Two-piece garments are often preferred for long cases because weight is shared between shoulders and hips. Radiolucent positioning platforms and arm supports help the team hold optimal access angles without repositioning.
What PPE is used during fluoroscopy?
Anyone remaining in the room during fluoroscopy normally wears a protective apron, a thyroid collar and, for staff close to the patient, protective eyewear. The lens of the eye is one of the most radiosensitive tissues, which is why the UK annual eye-lens dose limit was reduced to 20 mSv under IRR17. Mobile barriers and table shields add a further layer for operators and scrub staff.
How do you choose an X-ray apron?
Choose on verified protection first, then fit, then weight. Check the certified lead equivalence and the kV range the core material was tested to, confirm the style gives the coverage your work needs (front-only, wraparound or two-piece), and make sure it fits: IEC 61331-3 expects an operator apron to cover from the throat to at least the knees, including the breastbone and shoulders. Only then compare weight and comfort features such as weight-support belts and elasticated backs.
Lead vs lead-free radiation protection: what is the difference?
There is no single best core material; it depends on the X-ray energies you work with and how long the garment is worn. Traditional lead is a proven choice for higher-kV work. Lead-free and bilayer composites can be lighter and better suited to long wear, but their attenuation varies more with beam quality, which is why IEC 61331 introduced more representative test methods. Bilayer materials combine complementary shielding layers, including controlled use of lead, to balance attenuation, weight and cost. Always compare materials on their certified lead equivalence and tested kV range, not on weight alone.
What does lead equivalence mean?
Lead equivalence (mm Pb) states how much attenuation a material provides compared with solid lead of that thickness. The higher the number, the less radiation passes through: 0.25 mm Pb blocks a lot of scatter, 0.35 mm Pb more, and 0.50 mm Pb the most of the three. What matters is the dose that still gets through, so 0.25 mm Pb letting roughly 10% through and 0.50 mm Pb letting roughly 2% through is a large difference in a high-scatter room, even though the percentages look close.
The lead equivalence you need should be settled through a risk assessment with your RPA. Rothband supplies certified attenuation data for every garment to support that conversation.
How should protective garments be stored?
Hang them on a proper apron hanger or rack. Never fold, squash, drape over sharp hooks or sit on them. Poor storage is a common cause of internal cracks in the protective core, which is why departments use mobile and wall-mounted hangers, and skirt-and-vest racks for two-piece garments.
How often should radiation protection garments be inspected?
Regularly, with professional guidance suggesting a full inspection at least once a year, plus quick checks between. IRR17 expects protective equipment to be examined regularly. Quick visual and tactile checks pick up cracks, lumps, holes, sagging and broken fasteners early; periodic radiographic or fluoroscopic screening confirms the core is intact. New aprons should be screened on arrival for hidden manufacturing or transport damage.
When should X-ray aprons be replaced?
When they have cracks, tears, holes, sagging, damaged seams or fail screening; age alone does not fail an apron. Rejection criteria should be set locally with your Radiation Protection Adviser, particularly where a defect sits over a critical organ. Rothband offers an apron scanning service and X-Ray Track fleet management software to keep inspection records in order.
What protection is used in a cath lab?
Cath lab staff typically combine a protective garment, thyroid collar and protective glasses with table-side shielding and mobile barriers. Cardiologists, radiologists and scrub staff who work close to the patient during long fluoroscopic procedures are the priority for eyewear and thyroid protection. Two-piece garments and weight-support options are frequently specified for comfort over long lists.
