Zircon sand containing radioactivity is being used in the zirconium extraction process, metal casting, and in the ceramic and refractory industries. The sand is being widely distributed as weight in ordinary tape dispensers. Use of the sand by foundries and the zirconium industry has resulted in the accumulation of large volumes of low-level radioactive waste. Radium-226 concentration in typical zircon sand was measured as 90±3 pCi/g. Radon emanation from zircon sand was estimated as 2 pCi/m2sec.
