{{Advert|date=June 2023|type=promotional material}}{{short description|Non-toxic and flexible polymer radiation-shielding fabric}}

Demron is a radiation-shielding fabric. For the same weight it has slightly lower radiation protection than lead shielding, but is flexible.{{cite web|title=Radiation Shield Technologies (RST) - Research Results |url=https://www.radshield.com/RST_Livermore_Summary.pdf |accessdate=2008-01-02 |url-status=dead |archiveurl=https://web.archive.org/web/20080820132825/http://www.radshield.com/RST_Livermore_Summary.pdf |archivedate=2008-08-20 }} The composition of Demron is proprietary information, but it has been described as a non-toxic polyethylene and non-PVC-based polymer fused between two layers of a woven fabric. The polymer molecule imitates the electronic traits of heavy metals, commonly employed for shielding against radiation. It has a significant electron cloud that either deflects or absorbs incoming radiation. {{cite web|url=https://www.newscientist.com/article/dn3050-lightweight-radiation-proof-fabric-unveiled/#ixzz6GHlOY0xo |title=Lightweight radiation-proof fabric unveiled |date=15 November 2002 |first=Marina |last=Murphy |publisher=New Scientist Ltd. }}{{cite web |url=https://www.radshield.com/demron/ |title=Demron is a radiation-blocking fabric made by Radiation Shield Technologies |website=www.radshield.com |accessdate= 10 March 2020 }} 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.{{cite news | title = Radiation-proof fabric developed | publisher = Associated Press | date = 2002-11-14 | url = http://news.bbc.co.uk/2/hi/science/nature/2478465.stm | accessdate = 2006-10-24}} More recent uses for Demron include certified first responder hazmat suits as well as tactical vests.
