Protective Paper

A new paper has been developed that has radiation-blocking properties similar to lead without the potential harmful side effects. At a standard thickness of 0.3 mm (slightly more than one-one hundredth of an inch) it can be cut and folded like ordinary paper, yet a single piece will block 50% of the radiation from a typical x-ray.

The key to its superior shielding properties is a new technique that incorporates tungsten directly into the paper fibers at a high density. Applications include protective gear for use in radiation-contaminated areas and for walls or curtains in radiology areas of clinics and hospitals.

Samples are available at a cost of about $100 for a 20-inch square.
