This is what the review actually says:

10.3 RADIATION
10.3.1 GENERAL
Commitment 12 The ALARA principle (which requires that exposures to radiation be
kept as low as reasonably achievable, taking into account social and
economic factors) would be adopted for all components of the project.
10.3.2 LEGISLATIVE COMPLIANCE
Commitment 13 The Commonwealth requirements for radiation control outlined in the
Code of Practice on Radiation Protection in the Mining and Milling of
Radioactive Ores 1987 and the Code of Practice on the Management of
Radioactive Wastes from the Mining and Milling of Radioactive Ores
1982 would be met. Similarly, the Western Australian requirements
for radiation control outlined in the Radiation Safety (General)
Regulations 1983 would be met.
10.3.3 RADIATION PROTECTION DESIGN TARGETS
Commitment 14 Under Ashton's commitment to the ALARA principle, radiation
protection design targets to be adopted for all employees would be less
than 2 mSv/a and would not require designation of employees as
radiation workers, which would allow a 20 mSv/a dose limit under the
International Commission on Radiological Protection draft
recommendations (1990).
Commitment 15 Under Ashton's commitment to the ALARA principle, radiation
protection design targets to be adopted for members of the public
would reduce the statutory 1 mSv/a required by the Commonwealth of
Australia's Code of Practice on Radiation Protection in the Mining and
Milling of Radioactive Ores 1987 to 0.05 mSv/a

Chinsyndrome, can you provide any evidence to back your claim that "When this Project was first looked at by Ashton in May 1992 they recognised that there was a problem with Radiation in the Pit, and accordingly limited any Mine Worker to no more than 30 days per annum !"
