Potential health effects
Acute Swallowed: Non-toxic, although ingestion of large quantities may cause irritation of the gastrointestinal system as a result of abrasive action. Eye: Sand is an irritant, due to abrasive action. Skin: Not absorbed through skin. May cause abrasions. Inhaled: Irritating if inhaled in high concentrations, causing coughing, shortness of breath and/or sneezing. Chronic Zircon contains naturally occurring radioactive elements of the uranium and thorium series and free silica. The feedstock contains low concentrations of these impurities, with typical specific activities of 0.6 to 0.9 Bq/gm (thorium- 232) and 1.5 to 3.4 Bq/gm (uranium-238). Daughter products are present typically at equilibrium concentrations. The main radiological hazard is internal exposure to alpha particles from inhaled dust. Suitable dust control measures shall be employed to ensure occupational exposure to generated dust and alpha particles are kept as low as reasonably achievable. As a guide, continuous worker exposure to respirable dust levels above 1.5 mg/m could 3 give rise to annual internal exposures above 1 mSv. External exposure is from gamma radiation. Continuous exposure (2000 hours per year) within 2 metres of bulk zircon could give rise to an annual external dose above 1 mSv. Radiation exposure from stored product presents a considerably lower hazard.
