Imaging Solutions has developed and formulated RADsafe’s core materials, RADcore in response to market demand for safe and reliable protection against ionizing radiation.
You can be assured that RADcore materials will provide the protection and compliance specified as a result of highly evolved quality processes which are also supported by random and periodic independent RADlab attenuation testing. Our own design and manufactured core materials, Optima, Assure and Lite, are high-performing materials that are designed and formulated to meet various leading international standards including IEC, DIN and ASTM. RADcore materials are all lead-free and leverage the radiation attenuation characteristics of elements such as antimony and bismuth, which are encapsulated in an advanced plasticized polyvinyl chloride formulation. RADcore material formulations have been optimized to provide high radiation attenuation performance at reduced weights under relevant standards while retaining their strength, flexibility and durability, making them the perfect option for your personal radiation protective needs. RADcore material formulations are also REACH compliant, and being lead-free, these materials can be disposed of without the hazardous challenges of handling lead or other chemicals that pose high risks to human health and the environment.

Balanced
RADcore OPTIMA™
RADsafe Optima core material utilises bilayer design to achieve high radiation attenuation performance and minimal secondary radiation across a range of x-ray energies while also featuring reduced weight compared to traditional lead vinyl and single layer core materials of similar comprehensive radiation attenuation performance.
RADsafe Optima’s performance characteristics are achieved by leveraging the high primary radiation attenuation to weight performance of the element antimony in the outer layer while ensuring secondary radiation attenuation with the element bismuth in the inner layer, these layers are thermally fused together into a single bi-layer material ensuring consistency, durability, and inner strength.
RADsafe Optima core material is compliant to all leading direct and broad beam international standards including IEC 61331- 1:2014, DIN EN 61331-1:2016, ASTM F2547-18 and ASTM F3094-14.
RADsafe’s Optima core bilayer design achieves an approximate 20-40% reduced absorbed dose when compared to lead, lowlead and non-lead single layer core materials. Its overall holistic approach to protection provides a measured lead equivalency up to 45% greater than that of traditional antimony dominant direct beam compliant materials when tested to broad beam methodologies.
RADsafe Optima core material has been designed with the clinician in mind, it provides for the perfect balance of protection and ergonomics and is suitable for all personal radiation protection products.
Ergonomic
RADcore LITE™
RADsafe Lite core material is a single layer, antimony dominant material yielding high primary radiation attenuation performance at specific x-ray energies, it minimises the antimony required and forgoes high concentrations of other elements that provide improved secondary radiation attenuation for significantly reduced weight when compared to other core materials and especially standard lead vinyl.
Given this RADsafe Lite core material is only compliant to the ASTM F2547-18 direct beam standard and potentially other direct/narrow beam standards which don’t provide for the measurement of secondary radiation.
RADsafe Lite core material is compatible in personal radiation protection where there is a high ergonomic requirement and reduced concern for holistic radiation attenuation performance.
Ultimate Protection
RADcore ASSURE™
RADsafe Assure core material is a single layer, bismuth dominant material yielding high primary and secondary radiation attenuation performance across a wide range of x-ray energies while feature a modest weight reduction compared to traditional lead vinyl.
RADsafe Assures performance characteristics are “lead-like”, its measured lead equivalence closely resembles that of lead, this is primarily due to bismuth’s atomic element positioning to that of the lead benchmark.
RADsafe Assure core material is compliant to all leading direct and broad beam international standards including IEC 61331- 1:2014, DIN EN 61331-1:2016, ASTM F2547-18 and ASTM F3094-14.
RADsafe Assure core material provides for as the name implies, Assured protection when compared to the lead benchmark, it is suitable for all personal radiation protection products where weight is not a primary concern, it is ideal for patient protection.
