The uranium exploration in Brazil began in 1982, in the city of Caldas (MG); In 1995 INB found that it was not economically viable the operation of the unit and shut down its activities. Ten years later, it was started the decontamination of its facilities and land.

At INB Caldas is installed the Environmental Laboratory of Chemical and Radiological Analysis which performs the analysis that are necessary for the monitoring of the environment in areas where units of the INB in Bahia, Ceara, Minas Gerais and São Paulo work.

The facilities, the soil, the water and the old mining equipment are permanently monitored, as well as the radioactive materials that are stored there in order to protect the environment and ensure the health of the workers of the unit and of the local residents.

In 2012, IBAMA approved the Degraded Areas Recovery Plan (PRAD), which is currently under review in the National Nuclear Energy Commission. This Plan is the result of studies in the areas of hydrology, geochemistry, hydrochemistry, radioprotection done to indicate the work that is going to be performed and the environmental recovery actions to be developed in the unit.
