Pro-GR

Product catalog summary

Overview: Pro-GR is a specialized gamma ray shielding glass developed for use in PET scan facilities, where higher radiation shielding is required compared to conventional X-ray or CT rooms. It contains approximately 70% lead oxide, similar to glass used in nuclear power facilities, and offers superior shielding compared to conventional x-ray shielding glass.

Applications: The primary application of Pro-GR is in PET treatment facilities, where it serves as an observation window providing enhanced radiation protection.

Shielding Performance: The shielding performance of Pro-GR against 0.511 MeV gamma rays is calculated using Monte Carlo simulations. The effective dose transmission factor is determined in accordance with the Manual for Shielding Calculation of Radiation Facilities, 2000. Pro-GR is designed to have a lead equivalent thickness that matches the effective dose transmission factor of lead, taking into account the build-up factor.

Product Specifications:

Pro-GR 14.7 mm: Effective Dose Transmission Factor of 52.6%, Lead Equivalent of 5.0 mmPb, Maximum Size 1,000 x 1,500 mm, Specific Gravity Min. 5.20, Knoop Hardness 320, Visible Light Transmission 83%.
Pro-GR 21.8 mm: Effective Dose Transmission Factor of 36.0%, Lead Equivalent of 7.5 mmPb, Maximum Size 1,000 x 1,500 mm, Specific Gravity Min. 5.20, Knoop Hardness 320, Visible Light Transmission 83%.

Additional Notes: The presence of "seeds" or minute air bubbles in Pro-GR does not affect its radiation shielding performance. The document also provides a comparison of effective dose transmission factors for different thicknesses of lead and corresponding Pro-GR thicknesses.

I ^/T A one source, many solutions.® ■ ■ ■ ■ GAMMA RAY SHIELDING GLASS GAMMA RAY SHIELDING GLASS Pro-GR lead shielding glass was developed to protect against high radiation gamma rays used in PET scan facilities. An observation window of a PET scan facility requires higher radiation shielding performance than that of a conventional X-ray or CT room (0.511 MeV). Pro-GR is made of glass materials having a lead oxide content rate of roughly 70% that is equivalent to ultra-high lead content block glass for nuclear power facilities. Pro-GR has a radiation shielding capability higher than that of conventional LX-57B, x-ray shielding glass.
