Urgeiriça is a portuguese village in the parish of Canas de Senhorim, in the municipality of Nelas, district of Viseu, known locally by its radium and uranium mines, which worked since 1913 until their closing in 2001.

[1] Radium mined during the early years of this site supplied Madame Curie and, during World War II, control of the uranium resources was a source of concern for the dueling countries.

Many countries have purchased uranium mined and then processed into yellowcake from this site including Iraq in 1980.

The Urgeiriça mines were managed by the National Uranium Company (Portuguese: Empresa Nacional de Urânio – ENU) between 1977 and their closing.

The working conditions were particularly harsh, with 9 consecutive hour shifts in extreme humidity and with poor air quality, filled with small particles, including radioactive ones and radon gas,[1] as well as the extensive usage of sulfuric acid inside the mines.
