VeriShield - Model HT -Modular Radiation Shielding Component

VeriShield radiation shielding components are individual modules combined together to form a composite structure to create the required radiation attenuating environment. The constructed system retains the ability to be deconstructed and reused.

VeriShield products are manufactured in a controlled environment and incorporate high Z aggregates (for photon attenuation) as well as neutron additive materials. The VeriShield photon, neutron and electron shielding modules feature a design that presents a full 100% inter-locking edge. Lapping or alternating of the seams results in the prevention of straight line paths for radiation streaming. Modules interlock together to form a solid and stable structure.

The VeriShield V250HT block is designed to allow the full thickness VeriShield V250 blocks to be offset 2-1/2″ (64mm), which allows the sine-wave shapes to interlock. This results in additional structural strength of the stacked blocks.

Compressive strength is guaranteed to meet 2,800 psi. This product routinely easily surpasses this minimum and is typically on the order of 5,200 psi.

Standard VeriShield HT blocks are 2 1/2″ x 5″ x 10″ (64 x 127 x 254mm).

RADIATION ATTENUATION
Attenuation is based on interpolated data for some energies. The listed TVL’s represent the average tenth value thickness after 5 decades of attenuation. First TVT and equilibrium TVL’s may be available for thin barrier sections.

Veritas will provide calculations with appropriate safety factors to ensure attenuation requirements are met. Please refer to individual VeriShield data sheets for specific radiation attenuation figures.
