Scatter Sentry™ Our Bi-layer Product

Scatter SentryReady for a lightweight apron with high-performance radiation protection? It’s here: Scatter Sentry™, the newest radiation protection material exclusively from Bar-Ray Products.

More comfort, better radiation protection what’s not to like?

The Latest in Innovative Radiation Protection

Bar-Ray has always been committed to combining maximum radiation protection with minimum weight material, and we keep our product developers busy seeking ever-better materials and solutions.

Our latest innovation, Scatter Sentry™, joins Bar-Ray’s collection of radiation protection aprons—Prestige, Starlite, Truelite and Cost Cruncher—to provide our newest shielding material yet. There’s plenty to love about Scatter Sentry™:

  • Meets current ASTM, IEC and DIN guidelines.
  • IEC 61331-1 (2014) compliant. IEC compliant aprons are somewhat heavier than equivalent non-compliant aprons. To be truly compliant, manufacturers must follow IEC apron protection coverage and size criteria.
  • Scatter Sentry™ is a recyclable product.


Larger Bodies, Increased Scatter Radiation

Fluoroscopy’s radiation hazard comes mainly from X-rays scattered from the patient’s body. Scatter intensity varies substantially with the thickness of the anatomic parts being examined. Heavier patients have thicker bodies, which produce more scatter radiation.

Scatter Sentry™ Protection and Comfort

Scatter Sentry™ provides optimal protection from scatter radiation for fluoroscopy imaging professionals. Bi-layer material is lightweight and flexible, and created using a new, more realistic measure of radiation protection. Scatter Sentry™ is developed with new testing methods from ASTM International, the International Electrotechnical Commission, and the National Research Council of Canada.

Why Use Scatter Sentry™ Radiation Protection Aprons?

  • New testing methods are being adopted to take into account the different characteristics of no lead or low lead shielding materials.
  • Traditionally, shielding materials were tested for lead equivalence using a narrow beam attenuation set-up; ASTM F2547-06 (2013) or IEC 61331-1:1994
  • The use of no lead or low lead shielding materials has caused two testing complications:

1. Different elements attenuate X-rays better at certain energies; this means the lead equivalence of no lead or low lead will vary depending on the energies used in the test.

2. Traditional narrow beam attenuation testing may not accurately measure the protection of no lead or low lead shielding materials.

  • The new testing method incorporates an inverse broad beam attenuation set-up; ASTM F3094(2014) or IEC 61331-1:2014
  • Scatter Sentry™, our bi-layer product, conforms to the new IEC61331-1:2014 standards for customers who would like to adhere to these newer testing methods.
