ClearShield™ wherever x-ray shielding is required
MEDICAL • INDUSTRIAL • NUCLEAR • GOVERNMENT LABS • MILITARY
ClearShield is a transparent, lead-free, sheet of styrene-acrylate copolymer that contains about 30% by weight bismuth. The bismuth provides X-ray shielding properties comparable to lead (Pb).
the ClearShield Safety Data Sheet (SDS) for health and safety considerations prior to ClearShield fabrication.It is highly recommended that the user determine cutting/drilling speeds, feed rates, and other machining parameters on a scrap piece of ClearShield before fabricating a finished piece. To protect the surface of the material, leave the protective masking paper in place during fabrication. Provide adequate ventilation to manage dust, which may be a lung irritant. If adequate ventilation cannot be provided, a mask or other physical barrier to prevent inhalation is recommended.
Storage:Store ClearShield horizontally. Place a sheet of cardboard on both sides of the ClearShield sheet and, if stacking, between each sheet. The storage base should be a sturdy, flat platform such as a sheet of plywood. Avoid extreme temperatures and high humidity.
Handling:Carefully remove ClearShield from packaging to prevent damage. Both sides of the ClearShield sheets are protected by masking paper. Do not remove the masking paper until the material is mounted and ready for the intended use. When moving with a forklift, take care to avoid scratching, chipping, and cracking. Always lift material, never slide. Additional care should be taken to exercise caution when handling fractured or machined edges of ClearShield to avoid cuts or injury.
Radiation Inspection:Radiation inspections should be performed with the ClearShield part in the “as used” condition to verify acceptable radiation attenuation for the application.
