1. IDENTIFICATION OF THE MATERIAL AND SUPPLIER

Zircon sand contains low levels of naturally occurring radioactive elements of the uranium and thorium series. It has typical specific activities of 0.6 to 1.2 Bq/g (thorium-232) and 1.5 to 4.5 Bq/g (uranium-238). Low level gamma radiation from bulk or bagged stockpiles of zircon sand can increase gamma levels slightly above normal background.
