Australia should follow Canada- producing medical isotopes in cyclotron, not nuclear reactor

Steve Dale     Nuclear Fuel Cycle Watch South Australia, 5 Aug 18 Is this what they call a strawman argument? Who wants to import isotopes? I don’t want Australia to import isotopes, I want Australia to make them here using Cyclotrons and other forms of accelerators. If you read the author’s twitter feed you will see he is strongly advocating for nuclear power reactors, which makes you wonder if he is looking at isotope production objectively.

Here are some things to think about –
– dissolving Uranium plates to extract the Moly is a process that produces a lot of waste with many steps in the process that have potential for failure or human error
– using Low enriched Uranium plates produces much more waste than High enriched Uranium plates (obviously neither is desirable)
– apparently there is a move away from Technetium99 because it is considered low resolution imaging, some predicting that it will not be used in 10 years because of the superior imaging of PET/cyclotron isotopes
– the isotopes generated in a cyclotron have a very short half life, so they can be kept for a few days and thrown in the general trash

So to summarise. Moly99/Technetium99 is on the way out, yet tax payers have funded a factory to build a factory that can only make Moly99/Te99 – unlike a cyclotron that can make all sorts of isotopes. And instead of building a facility to cater for our own supply, they have built a taxpayer funded factory to speculate on the world wide isotope market.

Canada is showing another way using cyclotrons-
“”The newer radionuclides that are used, the so-called PET imaging agents, give a much more high-resolution picture,” said Wilson. “We’re slowly moving toward more PET isotopes.” https://www.facebook.com/groups/1021186047913052/permalink/2053022201396093/?comment_id=2053155368049443
