HARLOW, K.. Naturally occurring radioactive materials and the regulatory challenges to the zircon industry. J. S. Afr. Inst. Min. Metall. [online]. 2017, vol.117, n.5, pp.409-413. ISSN 2411-9717.  http://dx.doi.org/10.17159/2411-9717/2017/v117n5a1.

Zircon is a naturally occurring radioactive material (NORM) and as such is subject to a variety of regulations around the world. The regulatory processes and their implementation are summarized and the key issues affecting zircon and zirconia highlighted. Having absorbed the activities of the former Zircon Minerals Committee, the strategy of the Zircon Industry Association (ZIA) is to be the 'go-to place' for information on these matters, and its activities in the NORM space are described. Chemical industry regulations such as REACH are spreading around the world, and the paper provides an update of their status in the key jurisdictions. As mineral sands are transported to market in oceangoing vessels, they are subject to the regulations of the International Maritime Organization, which are summarized in the paper.

Palavras-chave : zircon; zirconia; radioactivity; safety and health; environment; regulatory issues.
