What Is Radishield?tRadishield is a patented laminated flexibleelastomeric lead filled system developed to protectworkers in nuclear and associated industries fromharmful x-ray and gamma radiation.tIt is designed to shield areas where traditionalshielding materials such as lead cannot be used oris difficult to install.tDesigned to replace products such as PVCcovered lead impregnated rubber / pure lead whichhave definite disadvantages.

Radishield - A Brief HistorytOriginally designed for Rolls-Royce Powered Nuclear submarines.tDesigned to meet requirements and conditions of UK Ministry of Defence.tProduct range expanded and developed to provide applications in civil NuclearPower Industry.tComplete Projects undertaken.tCustomer Base expanded to worldwide

Types & Forms of RadishieldRADISHIELDSILICONE LEADSILICONETUNGSTEN(Lead Free)POLYURETHANELEAD

Radishield - Silicone LeadtOriginal Radishield versiontMaterial will not sag or slump likealternative products (pvc bags)tHigh temperature resistance(-50 to 200 C)tEasily decontaminatedttFlame Retardant (Fire Tested)Water/steam prooft Available in flat sheet form -standard or non-standard sizes /thicknessestVery flexibletAvailable in pipewrap, t-piece andbespoke moulded shapestLow chlorine,fluorine,sulphurcontent (suitable for contact withstainless steel)tCan be incorporated intocustomised containment unitstEasily cut and shaped by handtStandard Colour - Yellow

Radishield - Silicone TungstenttttttttDeveloped as a alternative to standard silicone Radishield products wherecustomers require a LEAD FREE alternative.Tungsten based inner laminate.Available in flat sheet or moulded shapesSame shielding and flexibility as standard Radishield.Fire TestedTested by National Radiological Protection BoardUS Navy ApprovedStandard Colour - Grey

Radishield - Polyurethane LeadttttttttDeveloped as a lower cost alternative to Silicone Radishield where ultimateproperties of Silicone based versions are not required.Same shielding (attenuation) as silicone Radishield.Lower max temperature ( 40C).Low chlorine, fluorine, sulphur content not applicable.Slightly less flexible.Significantly lower cost.Available in FLAT SHEET FORM ONLY(standard / special sizes / thicknesses available)Standard colour - Green

Radishield MouldingstRadishield Moulded Shapes may bedesigned & manufactured to fit individualcustomers applications.tRadishield mouldings are extremely fastto install therefore drastically reducingshielding time and high dose rates oftenassociated with the installation ofconventional shielding.tRadishield custom mouldings aredesigned to accurately fit application andthus reducing radiation shine paths.

Radishield PipewrapstRadishield Pipewraps aremanufactured for fast and easyfitment. They may be used forpermanent or temporaryshieldingtThe can me manufactured tomeet customers requirementsincluding pipe size, shieldingthickness and to meetallowable weight restrictions.tPipewraps may be supplied tocustomer dimensions or CADdesigned from customerpipeline drawings.

Radishield T Pieces & Valve CoverstTo compliment pipewraps, t-pieces andvalve covers cam be manufactured in avariety of shapes and sizes to meetindividual specifications and shieldingsituations.

Bespoke Moulded ShapestRadishield Mouldings may be manufactured to fitcustom applications with no restrictions onminimum quantities

Nuclear Power GenerationtNuclear power stationstSuitable for both operable and decommissioned units.tTemporary or permanent shielding.tMoulded shapes popular (e.g. pipewraps).tProject work – Mazel design and manufacture bespokeShielding to meet customers individual shielding problems

Nuclear Installation, Reprocessing and DecommissioningtInstallation – Mazel supply Radishield to both main customers andcontractors involved with nuclear sites.tRe-processing - companies involved with conversion or disposalof radioactive materials (waste) e.g BNFL Sellafield.tDecommissioning - companies contracted to remove, make-safeand monitor safety at disused nuclear sites (e.g. power stations,research sites etc).
