If you have a heart attack, it's fairly likely that the doctor will inject you with a Technetium-99 tracer. Technetium is supplied to hospitals by packaging Molybdenum-99 into a generator: Molybdenum-99 decays into Technetium in the generator over about a week, and the Technetium extracted and used for diagnostic procedures.
But there's a problem. Right now, large quantities of Molybdenum-99 can only be made in a few specialised nuclear reactors, all of which are becoming too old to be run safely, and recent failures in the two principal reactors have created a crisis in supply, at a time when there is an ever-growing demand. To put it into context, 36 million nuclear medicine procedures were carried out last year, most of which need Technetium.
We are looking at a new method to produce Technetium using a particle accelerator. Using similar technology to that used in particle colliders like the LHC, to accelerate ions into a target to generate neutrons. Like in the reactors they intend to replace, these neutrons can then be used to make Molybdenum-99. Although an RFQ cannot make as many neutrons as a reactor, it is much cheaper to build and operate, and so many could be built around the country to provide a domestic supply of Molybdenum-99, which the UK doesn't have at the moment despite using over a million doses of Technetium a year.
