November 30, Haicang Inspection and Quarantine Bureau in accordance with the law on a number of radioactive seriously exceeded the Nigerian zircon sand implementation of return processing, which is Xiamen Haicang port for the first time returned unqualified zircon sand. Has been in the port inspection and quarantine work in the 20 years of the Chief Lin introduced,260 times more than the radioactive zircon sand is the first encounter.

      The batch of zircon sand weighing 82 tons, the value of nearly 30,000 US dollars, with four 20-foot container loading. Haicang Bureau staff to implement the out-of-the-box test, found that the site of radioactive detection value of 53.37-62.31 micro-Sv / h, the batch of zircon sand gamma dose rate level value exceeds the local environmental radiation background value 260 times . The inspection and quarantine department shall keep the notice in isolation, prevent the unrelated personnel from approaching, and inform the relevant operation departments to do a good job in safety protection.

       Zircon sand is mainly used for refining zirconium oxide, zirconium silicate and zirconium compounds in casting, chemical, ceramics, optical glass and refractory industries. It is widely used in the production of tableware, sanitary ware, ceramic tile and decorative ceramics. And other products. As the zircon sand products contain natural thorium, uranium, radium and potassium and other radioactive elements. If these radioactive elements content is high, easy to produce high-level radioactive substances. Can damage the human cell tissue, resulting in mutations, resulting in injury not only carcinogenic, teratogenic, while in the refining process of high-radioactive substances likely to cause long-term environmental pollution, threatening human And animal and plant safety and health.

    In this, the Haicang Inspection and Quarantine Bureau to remind the relevant import and export enterprises in the foreign trade contract terms zirconium should be signed in the radioactive limit requirements, while the strict implementation of radioactive detection before shipment, Resulting in unnecessary economic losses.
