This special Syringe Shield is manufactured to provide shielding for 511 keV nuclides.
The 511 Syringe Shield is made of Tungsten with a 0.5" lead equivalency. It has a viewing area of 0.75" thick lead glass surrounded by a rubber grommet to prevent damage to the glass. Fluorescent gold gloss covers the interior of the syringe shield for exceptional visibility of the syringe contents.
An optional "Double Clip" security holder is also available.
