What is the NEW ALARA Shield blanket?

Updated: Sep 20, 2021

The Demron™ ALARA Shield blanket is a contemporary shielding solution for gamma and X-Ray radiation. The fabric can be configured in industry standard shielding blankets or curtain designs as well as in unique, customizable designs.

Utilizing a patented material that is a mixture of heavy metal and polymers, the ALARA shielding material allows for an industrial shielding solution that is lighter in weight than lead and is Non-Toxic. Therefore, when the Demron material becomes contaminated with residual radioactive contamination it is NOT A MIXED HAZARDOUS Material such as traditional lead.

The material is available in 6 or 12 layer thicknesses

Key Benefits:

  • Significantly lighter weight (pounds/square foot) compared to lead; Results in reduced resources and person dose required to deploy/collect

  • Non-toxic material; eliminate mixed hazardous waste concerns typically encountered with lead

  • Customizable size and thickness solutions; can develop a specific solution for a given application

  • The outer layer of material is easily wiped down/decontaminated due to Herculite outer layer

  • Large Area Blankets/Curtains can be designed with grommets or magnets to facilitate easy hanging and attaching to surfaces and locations

Blanket Use Cases:

  • Pipe/component shielding

  • Outage/Reactor Head/Cavity shielding

  • Tool/Component shielding

  • Rad Monitoring or Contamination/Portal Monitoring shielding

  • Shadow or Large Area shielding

  • Rad Waste/HIC Container shielding

  • Glovebox/sampling skid shielding

Custom Use Cases/Industry Examples:

  • ​In-core detector shielding bag

  • Reactor Coolant/Demineralizer filter transfer Container shielding

  • 55-gallon drum lid shield covers

  • Shielded Work or Hot Tool Bag (used to move material with hot particle)

  • Low Dose shielding Decon Tents

  • Fuel Handling Crane and Tool customized shielding

  • Neutron Flux (Gamma metrics) detector box slipcovers
