What Is Radishield?What Is Radishield?

Radishield is a patented flexible elastomeric lead filled system developed to protect workers in nuclear and associated industries from harmful x-ray and gamma radiation.

It can be used to shield areas where traditional shielding materials such as lead cannot be used or is difficult to install.

Designed to replace products such as PVC covered lead impregnated rubber / pure lead which have definite disadvantages.

Types & Forms of RadishieldTypes & Forms of Radishield

Radishield comes in 3 main types:

Silicone Radishield

Polyurethane Radishield (Radishield 50 flat sheets)

Lead Free Radishield

Silicone RADISHIELDSilicone RADISHIELD Original Radishield (yellow)

High temperature resistance(-50 to 200 C - 250C intermittent)

Flame Retardant

Water/steam proof

Very flexible

Low chlorine,fluorine,sulphur content (suitable for contact with stainless steel)

Easily cut and shaped by hand

Material will not sag or slump like alternative products (pvc bags)

Easily decontaminated

Available in flat sheet form -standard or non-standard sizes / thicknesses

Available in pipewrap, t-piece and bespoke moulded shapes (laminated or un-laminated)

Can be incorporated into customised containment units

Polyurethane RADISHIELD Polyurethane RADISHIELD Developed as a lower cost alternative to silicone Radishield where ultimate

properties not required.

Same shielding (attenuation) as silicone Radishield.

Lower max temperature ( 50C).

Low chlorine, fluorine, sulphur content not applicable.

Slightly less flexible.

Significantly lower cost.

Available in FLAT SHEET FORM ONLY (std colour - green).

Available in standard or special sizes / thicknesses.

Lead Free RADISHIELD (New)Lead Free RADISHIELD (New)

Developed as a alternative to standard Radishield products where customers require a LEAD FREE alternative.

Tungsten based inner laminate.

Available in Silicone or Polyurethane versions

Same shielding and flexibility as standard Radishield.

Available to order in standard or special sizes / shapes

Tested by National Radiological Protection Board

US Navy Approved

N.D.T (NonN.D.T (Non--destructive Testing)destructive Testing)

The examination of metalwork integrity by means of radiography.

Can be x-ray or gamma ray. Numerous companies sub-contracting to larger companies ( e.g.

pipeline, offshore etc)..Very competitive. Radishield required to reduce safe working distance, thus

reducing costs and downtime. Often Radishield 50 (low temperature, low cost). Specially developed shrouds and guide tube shields (patented). Usually smaller quantities required.
