Radiation shielding material Heavy metal sheets (Tungsten sheets)

Advanced polymer material primarily composed of tungsten having high density and high radiation shielding performance. Since no lead is used at all, this is a clean material.
It has about the same elasticity and flexibility as ordinary rubber so it can easily be cut according to places and shapes to use.
Since if it comes in contact with foods, it is harmless, it can be used as sheets for food inspection, as well as for radiation shielding in places where flexibility is required, weights, vibration absorbing products (dampers) and noise-shielding sheets.
(Standard size 295 x 295 x 1.0 m. Larger sizes are also available upon request.)
