Thoriated Glass Lens From a Vintage Kodak Camera

Size: 21mm in diameter and about 7 mm thick.

Thoriated glass is a glass material used in the manufacture of optical systems, specifically photographic lenses. It is useful for this process due to its high refractive index and may contain up to 30% by weight of thorium.

If the lens has developed a brown tint over time, the discoloration can be mitigated by exposing the lens to ultraviolet light.

Th-232 is an optimal choice for calibrating Radiacode devices, as they require three distinct calibration points within the same measurement at energy levels of 65, 583, and 2614 keV

We also offer fluorescent sources that can't be found on this platform.
