Lead-free transparent radiation shielding material

We are developing a lead-free transparent radiation shielding material with radiation protection capabilities equivalent to lead-containing acrylic by incorporating low-toxicity bismuth (Bi) into the resin.
This material can be customized hardness in hard plastic-like to soft rubber sheet-like, by adjusting the resin composition.
These materials can also be endowed with anti-fog properties.
