Shielding X Ray Rooms - The basic and a CT Example

Thank you for your question and glad you found the webinar helpful.
1.9 mm to 2.2 mm refers to the equivalent thickness of lead that is included in the glass to provide the shielding capacity.
Lead glass is generally marketed with values for the lead equivalence that relate to the amount of lead included in the glass. It does not have any relationship to the thickness of the lead glass.

Thanks! great video but what do you mean with 1.9mm to 2.2mm on control window? Usually lead glass window are 15-20 mm thick?
