A survey programme was initiated several years ago with the aim of estimating the incidence of naturally occurring radioactive material (NORM) exposure for workers in the oil and gas industry, gold mining, spas, and a tourist cavern in Argentina. This work presents the procedures, methods employed, and results to date from the survey, including protection and remedial actions recommended when deemed necessary. Radium isotope concentrations measured in some samples were well above the exemption values established by IAEA Standards. Elevated radon levels (above the action level established for workplaces) were detected in the gas facilities, the gold mine, and the tourist cavern. The pertinent authorities and the facilities were informed of the detected values in order to take actions to reduce concentrations. In terms of the spas, almost all values for geothermal waters were below the corresponding guidance levels. Some regulatory aspects for the management of NORM are suggested.
