Stayer's Wrist Band (2005)

Stayer's, a fabric developed by the Fuji Spinning Company, Ltd. of Japan (aka Fujibo), employs a thread impregnated with microscopic thorium-bearing ceramic particles.  

According to the manufacturer, fabrics made with this material release natural radioactive gases and minus ions that have germicidal and deodorizing properties, and produce a soothing, relaxed feeling like that of a pleasant hot spring or forest. 

In this case, the fabric has been used in an wrist band consisting of two parallel woven "cords" with a plastic fastener (photo to right).

 

The ion-producing fiber is also used to produce knee and back supports for strains and sprains, in waist bands, neck bands, pillows, blankets, towels, bed sheets, mattress covers, shirts, socks, pajamas, lingerie, and underwear.

Count rate: barely detectable, approximately 25 counts per minute above background with pancake GM

Size: approximately 7" long "
