People with health concerns about a southeast Iowa factory where nuclear weapons were once made can attend a town hall meeting this afternoon in Burlington. Iowa Senator Tom Harkin says nukes were made at the Iowa Army Ammunition Plant north of Burlington between 1947 and ’75.Harkin says some people who worked in the plant are now suffering from cancer and other severe health problems which may be due to their exposure to nuclear materials. Harkin says U-S Secretary of Energy Bill Richardson will also be at today’s town hall meeting in Burlington.The Department of Defense will neither confirm nor deny whether nuclear weapons were ever made at the Iowa facility, but Harkin says the Department of Energy says — it’s true. Harkin says the Pentagon needs to “come clean” and release all of its information about the ammunition plant.The meeting is scheduled for 4 p-m at Burlington City Hall.
