Dewindtite from Loe Warren Zawn, Cornwall

Dewindtite from Loe Warren Zawn, Botallack, St Just, Cornwall, England, UK

Micro specimen containing yellow dewindtite and an unidentified uranium mineral. The uranium mineral glows green under 365nm light; it wasn't possible for me to get closeups of it, unfortunately.

Magnification is essential for these specimens.

#1 is of significantly higher quality - #2 has almost no detectable radioactivity.

• Toxic mineral: contains uranium, lead
• Radioactive mineral: approximately 0.5usv/hr at 0CM on a radiacode 2.
