Alaskan Cyclotron - Not in My Backyard!
j-beda writes "Wired reports that "Albert Swank Jr., a 55-year-old civil engineer in Anchorage, Alaska, is a man with a mission. He wants to install a nuclear particle accelerator in his home." To be used to create medically useful isotopes, and even though some of the neighbours are supportive, opponents "compared potential damage from a cyclotron mishap to the Three Mile Island nuclear reactor accident" though an expert says "Probably the worst thing that could happen with small cyclotrons is that the operator might electrocute themselves." It looks like the Anchorage Assembly plans to hold an public hearing on December 20 to determine whether Swank will be permitted to install the device."
This is just people being stupid. Also the reason they dropped 'Nuclear' from NMRI.
I was a Nuclear Power Technician in the US Navy. The week I arrived in Idaho for prototype training at the Idaho National Engineering Laboratory, scientists and nuclear engineers arrived from around the world to recreate TMI. INEL has about 200 nuclear reactors of all sizes and ages. They were all built for research purposes. They had one that they felt was similiar enough to the TMI reactor for their purposes. They recreated the conditions of TMI and let the reactor go to see just how bad it could have gotten. The result? As predicted, the nuclear reaction stopped when all the water was gone, there was some core damage due to residual heat. But that was it. No catastrophic melt down. No failure of the primary reactor vessel, no breach of secondary shielding. No measurable (ie higher than natural background) radiation levels were ever measured outside the fence at Three Mile Island. I don't minimize the emotions of the people who lived in the area at the time. Their fears were real. But those fears were a result of purposely inadequate education of the general public about nuclear science by the Government. It is much easier to protect a "secret" if no one understands what you are talking about.
I work in medicine. A cyclotron is just simply a big circular magnet. Electrocution from the power driving the magnets is the most dangerous thing possible, IMHO. Sheilding in the area where the drugs are bombarded by the machine to create the isotopes is quite adequate. Handeling procedures in place for these drugs and machines used in their production by the FDA, NRC, & other medical oversite organizations is very extensive. Here are just a few drugs off the top of my head that are used commonly that have short useful working span: Technetium-99m has a half-life of 6 hours. Fludeoxyglucose has a half-life of 109.8 minutes. C-11 methionine has a half-life of 20 minutes. ...and the list goes on.
Many drugs used in diagnosis & treatment of cancers & other ailments require an on-site cyclotron because of the short half-life. It is not possibly to make these drugs in the lower states & fly them to Alaska in a timely mannor for them to be effective for dianosis and/or treatment.
What this gentelman wants to do is needed & I commend him for trying to help others.The people who are against him building this thing are not very well informed.
