The Zircon Industry Association (ZIA) has published additional guidance on the transport of zircon as a NORM.
The first guidance document, the ‘Determining the Applicability of IAEA Transport Regulations to NORM Guidance’ document, contains information to help accurately assess the applicability of the IAEA Transport Regulations to NORM; to establish clearance levels for surface contaminated items; and to interpret regulations and guidelines regarding the signposting requirements for bulk NORM shipments.
The guidance includes an ‘Excel calculator’ to help with the complex calculations. This guidance and associated calculator are fully compliant with the latest version of the IAEA SSR-6 on the Transport of Radioactive Materials.
The second document is a best practice guide, ‘The Measurement of Gamma Radiation from Zircon and other NORM in Transport.’ It offers practical guidance on how to measure radiation levels of contained shipments, including supporting images and diagrams.
Dr Keven Harlow, Executive Director of the ZIA, said: “ZIA works to support its members and the wider zircon industry by providing guidance on industry best practice. As the authoritative voice of the zircon industry, ZIA has recently published a number of guidance documents relating to the transportation of zircon. These will support shippers in estimating the applicability of IAEA Transport Regulations to the shipment of zircon as a NORM and on establishing the requirements for signposting on bulk mineral shipments as well as offering clear and practical advice on taking radiation measurements. The calculator is also a valuable tool in determining accurate calculations.”
