Abstract

Naturally Occurring Radionuclides (NORs) are found in a wide range of commodities that are mined and processed in Western Australia (WA), such as mineral sands, tin, tantalum and the suite of ‘ battery minerals’ which include rare earths, lithium and cobalt.

An intense period of scrutiny was applied to the WA mineral sands industry during the mid- 1980’s to the mid-1990’s. Committed effective doses (CEDs) well in excess of the (then) applicable annual dose limit of 50 mSv were reported, leading to significant capital expenditure across the industry to reduce worker exposures...
