ABSTRACT:
X-ray attenuation, particularly for protective garments is provided by a film of a thermoplastic elastomer containing from about 60 to about 90 weight percent of barium sulfate or other barium salt. Films having a thickness of about 1 mm provide attenuation equivalent to that of about 0.2 to 0.25 mm of lead foil. The film is pliant, durable, and resistant to cracking from normal flexure during use and wear.
