I thank the member for Fremantle for giving me a tiny bit of
notice for this question; it was a bit late though as I was only given notice
at 2.10 pm. It is quite a detailed question. I cannot answer in detail but I
can give the member some information about the Lynas rare earth project.
(1)–(5)
The transportation of radioactive substances is regulated under the Radiation
Safety (Transport of Radioactive Substances) Regulations 2002, which is
overseen by the Radiological Council. The levels of radioactivity in the Lynas
rare earth concentrate are below the requirements for classification under the
radiation safety regulations. However, the regulations classify this material
as radioactive, and require signage to be placed at premises where storage
occurs for longer than 24 hours. Therefore, Lynas has advised it has placed
appropriate signage at the Bibra Lake holding yard and the various stevedoring
areas at the port of Fremantle in accordance with the regulations. The Lynas
radiation management plan, which has been approved by the Environmental
Protection Authority on advice from the Radiological Council, indicates that
exposure to the public under very conservative scenarios would be many times
less than the levels found in the natural environment.
