10-20% of the current stockpile would be the plausible range for medical waste − closer to 10% if measuring by radioactivity (because spent reactor fuel is such a large contributor to total radioactivity) and closer to 20% if measuring by volume.

“As health organisations, we are appalled that access to nuclear medical procedures is being used to justify the proposed nuclear waste dump. Most waste from these procedures break down quickly and can be safely disposed of either on site or locally.” 

− Dr Bill Williams, Medical Association for the Prevention of War

“Linking the need for a centralized radioactive waste storage facility with the production of isotopes for nuclear medicine is misleading. The production of radioactive isotopes for nuclear medicine comprises a small percentage of the output of research reactors. The majority of the waste that is produced in these facilities occurs regardless of the nuclear medicine isotope production.” 

− Nuclear Radiologist Dr Peter Karamoskos


Proponents of a national radioactive waste facility (a repository for lower-level wastes and a co-located store for higher-level wastes) claim or imply that nuclear medicine would be jeopardised if the facility does not proceed. There is no basis to such claims – they amount to dishonest scare-mongering.

Proponents claim that most or all of the waste that the federal government wants to dispose of or store at a national repository/store arises from medicine, specifically the production and use of medical radioisotopes. However, measured by radioactivity, the true figure is just 10-20%. Measured by volume, the figure may be within that range or it may be higher than 20% − but it takes some creative accounting to justify the claim that most or even all of the waste is medical in origin.

In any case, the fact that some waste is of medical origin doesn’t mean that a national repository/store is the best way to manage the waste.

If the plan for a national repository/store does not proceed, medical waste will continue to be stored at the Lucas Heights reactor site operated by the Australian Nuclear Science and Technology Organisation (ANSTO) and, in much smaller volumes, at hospitals. Some waste is used in hospitals and then sent back to ANSTO (e.g. molybdenum ‘cows’ that have been ‘milked’ of the daughter radionuclide, technetium-99m − by far the most commonly used medical radioisotope). That is no problem since ANSTO and hospitals continue to produce radioactive waste and thus they have an ongoing need for on-site waste stores and waste management expertise regardless of the options for periodic off-site disposal.

Nuclear medicine is not being adversely affected by the absence of a national radioactive waste repository/store. Nuclear medicine will not benefit from the creation of a national radioactive waste repository/store.

The incessant references to nuclear medicine to ‘sell’ the proposed radioactive waste repository/store amount to nothing more than emotive propaganda − which is what critics of the proposed national radioactive waste repository/store are routinely accused of.

Scare mongering

Successive governments have engaged in a scare campaign in relation to medical isotopes. Here are some examples:

·         Senator Nigel Scullion, who purports to represent the NT in the Federal Senate, said: “If we don’t have a site that is clear of any impediments by April [2006] then by December 2006 Australia will not get access to radio pharmaceuticals that are essential to the early diagnosis of cancer and to deal with many cardiovascular issues in Australia.” (13/10/05, Senator Scullion’s scare-mongering was proven to be false.

·         A joint media released by Nigel Scullion and David Tollner, the CLP Member for Solomon in the NT Parliament, said: “A delay [in building the waste facility] would severely limit the availability of life-saving radiopharmaceuticals used in the treatment of cardiovascular disease and early intervention against cancer, particularly breast cancer.” That one paragraph contains layers of confusion and misinformation. As the Medical Association for the Prevention of War noted, Senator Scullion and Mr Tollner were “peddling a lie” (ABC, 17/10/05).

·         National MP John Cobb said: “But let me ask this: do people want hospitals, do they want life-saving cancer treatment and equipment …? … I must stress how much medical waste is involved. I wonder whether those who have such a problem with it want to close down our hospitals.” (House of Representatives, 16 October 2003, pp.21329-30) Needless to say, no hospitals have been closed down, no hospitals will be closed down, no-one wants hospitals closed down.

·         In 2002, science minister Peter McGauran accused WA Premier Geoff Gallop of putting at risk life-saving nuclear medical research by refusing to accept that its waste had to be stored somewhere. (‘Premiers dump on waste site’, The Australian, August 7, 2002.)

Much of the pro-dump propaganda is somewhat less disingenuous than the comments of Senator Scullion, Mr Tollner, Mr Cobb, and Mr McGauran, implying rather than asserting that nuclear medicine would be jeopardised if the NT dump plan does not proceed. For example federal resources minister Martin Ferguson said in 2010: “We need a repository. We need nuclear medicine. All Australians benefit from the outcome of establishing a low and medium level repository in Australia, because half a million Australians a year demand access to nuclear medicine.” (

David Tollner said he approached then Prime Minister John Howard about funding an oncology unit at Royal Darwin Hospital as compensation for hosting a nuclear waste facility. (16/10/05, If there is a need for an oncology unit in Darwin, it would be totally unacceptable for federal support to be dependent on acceptance of a nuclear waste dump.

Fraction of the radioactive waste of medical origin

The federal Labor government − as with the previous government − routinely asserts that most of the waste is a by-product of the production and use of medical isotopes. Sadly, that false claim is sometimes echoed in the NT, as with the August 2011 NT News editorial which asserted that the waste arises “almost solely” from nuclear medicine.

Here are some examples of politicians peddling misinformation:

·         Then resources minister Ian Macfarlane said the nuclear waste arises “predominantly from medical services” (6/6/05,

·         Then science minister Peter McGauran said: “However, the Government remains totally and utterly committed to the safe and secure storage of low level radioactive waste − the bulk of which is produced from nuclear medicine procedures, and is the necessary by-product of life-saving medicine.” (24/6/2004,

·         Mr McGauran said that the waste destined for the national dump “is largely produced by nuclear medicine” (ABC Radio National, Australia Talks Back, 5/2/02).

·         In 1997, Mr McGauran said that “During this year more than 260 000 Australians will have a nuclear medicine procedure. … As a result of these procedures, some 35 spent fuel rods are generated by the Lucas Heights research reactor every year.” However just 10% of the spent fuel can be attributed to medical radioisotope production.

·         Then science minister Brendan Nelson said on 2/11/05 in Parliament that “… much of [the nuclear waste is] sourced from hospitals around Australia, which is currently stored at ANSTO. We have another 1,800 cubic metres at Woomera, much of that sourced from hospitals. In fact most of this stuff comes from hospitals. …” Hospitals account for only a tiny fraction of the waste (about 3% by volume). Just over 2000 cubic metres of low-level waste are stored at Woomera and none of it is of medical origin. Mr Nelson had no idea what he was talking about.

For low-level waste (LLW) and short-lived intermediate-level waste (SLILW):

* The claim that most of the waste is of medical origin certainly cannot be true in relation to waste volume, since 54% of the volume is non-medical CSIRO soil.

* A rough estimate would be as follows: say one quarter of ANSTO’s waste is medical (1320/4=330m3), and one third of the state/territory waste is medical (151/3=50 m3), so overall perhaps ONE TENTH (380/3700 m3) of the national inventory of LLW/SLILW is a by-product of medical isotope production and nuclear medicine. Or if we assume that one half of ANSTO’s waste is medical (1320/2=660m3), the overall figure is 710/3700 or 19%.

For long-lived intermediate-level waste (LLILW):

* Only a small fraction of this waste could be attributed to medical isotope production. Spent fuel accounts for a large majority of the radioactivity of Australia’s LLILW (though only a small fraction of the volume), and according to ANSTO (1993 Research Reactor Review submission), just 10% of the Lucas Heights ‘HIFAR’ reactor’s neutrons were used for medical isotope production. Presumably a similar figure applies for the new OPAL reactor − there is no reason to believe otherwise.

* Of the rest of Australia’s LLILW (other than spent fuel), about half by volume comprises reactor and isotope production wastes (limited detail is available), but this would account for only a small fraction of the LLILW inventory when measuring by radioactivity.

In sum, for LLW plus SLILW plus LLILW, 10-20% of the current stockpile would be the plausible range for medical waste − closer to 10% if measuring by radioactivity (because spent reactor fuel is such a large contributor to total radioactivity) and closer to 20% if measuring by volume.

For current and future production, roughly 30-40% of the volume could be attributed to medicine, but if measuring by radioactivity the figure would still be in the range of 10-20% (again because the radioactivity figures are dominated by spent fuel).

What should be done?

Two parallel processes should be initiated regarding radioactive waste management in Australia: a radioactive waste audit, and a National Commission or comparable public inquiry mechanism.

The federal government should immediately initiate an audit of existing waste stockpiles and storage. This could be led by the federal nuclear regulator ARPANSA in consultation with relevant state agencies with responsibility for radioactive waste. This audit would include developing a prioritised program to improve continuing waste storage and handling facilities, and identifying non-recurrent or legacy waste sites and exploring options to retire and de-commission these.

A National Commission would restore procedural and scientific rigour, and stakeholder and community confidence in radioactive waste management. It would identify and evaluate the full suite of radioactive waste management options. That would include the option of maintaining existing arrangements, keeping in mind that 95% of the waste is securely stored at two Commonwealth facilities: ANSTO’s Lucas Heights facility, and a large volume of very low level waste stored on Defence Department land at Woomera, SA.
