Objective The behaviour and dynamics of the distribution of radionuclides released by phosphate processing plants in the New Waterway were investigated. Although not all of the samples taken in the reporting period have been analysed or interpreted, some conclusions can be drawn. Increased concentrations of polonium 210 and radon 226 were found in sediments, suspended matter and dissolved in water, in front of and in the immediate vicinity of the New Waterway processing plants, clearly indicating the source of these radionuclides.
