Transparent Shielding Comparison

For a comparable attenuation of radiation and thickness, ClearView Radiation Shielding is superior to Lead Glass, Lead Acrylic and similar transparent shielding by 200% to 300%. Testing has demonstrated that ClearView will shield more than 20 different isotopes (shown in table below) used in Nuclear, Medical, Biological, Manufacturing and Food industries. ClearView’s Transparency, lightweight and superior shielding properties make ClearView most suitable for replacement of conventional transparent shielding for :

  • Shielding for Hot Cell Windows
  • Radiopharmocology, Oncology, and Imaging
  • High and Low Energy Gamma Isotope Shielding for Brachytherapy, Intraoperative radiation therapy, Nuclear Medicine.
  • Outperforming conventional transparent and high density neutron shields for Magnetic Resonance Imaging (MRI).

ClearView RS – A Construction Alternative in Radiation Shielding vs Concrete

A fabricated ClearView Shielding will provide greater attenuation, workability, and flexibility in radiation environments as opposed to concrete walls used as shielding for construction in Hot Cells, Fluoroscopy and other Nuclear Imaging & Medicine applications.

  Concrete ClearView RS
HVL, in (mm) 2.28 (60.5) 1.5 (38.1)
Mass of 20 inch dia shield, kg(lbs) 30.65 (67.68) 18.53 (41.57)

Additional Advantages:

  • At thickness of 2.28 inches, ClearView attenuates 82.11%, but concrete attenuates only 50%.
  • ClearView reduces dose better, being lighter than concrete with have a longer life time.
  • Unlike concrete, the ClearView will never degrade.

ClearView provides saving in thickness, thereby providing an increased work space. Comparisons are shown in the table below.

Shielding   Thickness Saving with ClearView *
Concrete   37 %
Water   79.17 %
Lead Acrylic (8mm, 0.3 mm Pb. equivalence)   87.2 %
Lead Glass (12 mm, 2 mm Pb.  equivalence)   43.18 %
Lead Acrylic (12 mm, 0.6 mm Pb.  equivalence)   85.8 %
