Uranium Fuel used for United States Navy reactors is typically highly enriched in uranium-235 (the exact values are classified). In a breeder reactor, uranium-238 can also be converted into plutonium through the following reaction: Before (and, occasionally, after) the discovery of radioactivity, uranium was primarily used in small amounts for yellow glass and pottery glazes, such as uranium glass and in Fiestaware. The discovery and isolation of radium in uranium ore (pitchblende) by Marie Curie sparked the development of uranium mining to extract the radium, which was used to make glow-in-the-dark paints for clock and aircraft dials. This left a prodigious
Uranium poisoning in Punjab early as 1995, Guru Nanak Dev University (GNDU) released a report, showing the presence of uranium and other heavy metals beyond permissible limits in water samples collected from Bathinda and Amritsar district, however there was no response from the government at that time. The hotspot for this increased toxicity, however was the Malwa region of Punjab, which showed extremely high levels of chemical, biological and radioactive toxicity, including uranium contamination. As the region's groundwater and food chain was gradually contaminated by industrial effluents flowing into fresh water sources used both for irrigation and drinking purposes, the region showed a rise
