Demron

Demron is a radiation-shielding fabric. Weight-for-weight the material has slightly lower radiation protection than lead shielding, however being flexible. It is essentially particles of metal embedded in a polyethylene-based material. The manufacturer claims it's a "liquid metal". It is roughly three to four times more expensive than a conventional lead apron, but can be treated like a normal fabric for cleaning, storage and disposal. More recent uses for Demron include certified first responder hazmat suits as well as tactical vests.
