the residues remained in São Paulo. The storage building in Interlagos has been criticized for its poor signage and safety protocols. There are few signs indicating radiation in the area, but they are small and some are covered by grass. According to Fernanda Giannasi, a public auditor from the Ministry of Labor, there are holes in the fence surrounding the building, which means people can enter the site. Giannasi has also noted risks faced by employees at the storage building. There are also complaints concerning the lack of instructions to residents in the vicinity advising certain steps in case of a radiological accident. When Usin was built, the population of the surrounding area was less dense. And the human presence in the area is expected to increase; the Santuário Theotokos Mãe de Deus, a large church with a capacity of 20,000 worshippers that will rise to 100,000 upon the completion of its construction, has been built only 300 meters (984 feet) away from the radioactive waste site. The company in charge of the uranium production in São Paulo was the former Nuclemon Mínero-Química, which has now been absorbed into INB. In 2007, the Brazilian Labor Court mandated that INB provide lifelong, free health insurance to the former workers of Nuclemon. This verdict was the outcome of a long lawsuit, which argued that throughout the 1980s and 1990s Nuclemon workers had no substantial information about the risks they faced and were constantly exposed to radioactive and toxic substances. A report from a parliamentary working group on nuclear safety noticed that, even though Brazil signed and ratified the International Labour Organization (ILO) Radiation Protection Convention (No. 115), it has not provided national measures that implement Article 12, which obliges signatories to commit medical services to former workers who have been in contact with radioactive substances. Discussions to implement Article 12 have been ongoing in Brazil's federal legislative body since 2006. Radiological accidents and incidents In 1986, roughly 20,000 to 25,000 liters of radioactive water accidentally leaked from the Angra 1 nuclear power plant, becoming a front-page story on the popular Brazilian daily Folha de S. Paulo on 9 October. In September 1987, a radioactive accident occurred in Goiânia, Goiás, after a radiotherapy device was stolen from an abandoned hospital site in the city. As different people subsequently handled it, men, women, children, animals, and plants were contaminated. In the cleanup operation, topsoil
