(wise-uranium.org)
As the local newspaper, the Tri-City Herald, reports, this has happened multiple times in the last five years, such as when a building demolition released plutonium dust that blew for miles, or when plutonium and americium particles contaminated workers' cars, including a rental later returned to the company. (uchicago.edu)
These "new" radioactive substances are called nuclides, which are so dangerous that, if inhaled, even just a thousandth of a gram of Plutonium-239 induces massive fibrosis of the lungs and can cause death within days (A pinch of uranium, a touch of technocracy and a lot of luck, by Richard Pollack).

In addition, the downloadable PDF v ersion of this educational series and other environmental medicine materials provides content in an electronic, printable format, especially for those who may lack adequate Internet service. (cdc.gov)
However, many materials have not undergone tests for every possible hazard, and illnesses are not always attributed to the correct causes. (goshen.edu)
Class 1: Explosives - This class includes materials that can rapidly release gasses, heat, and energy, causing an explosion. (osha-safety-training.net)

Other mines however can operate successfully with very low grade ores, down to about 0.02% U. Uranium mines operate in some 20 countries, though in 2022 over 55% of world production came from just 10 mines in five countries (see Table 1). (world-nuclear.org)
