dc.description.abstract | The estuary of the Odiel River has been affected by both direct discharges of phosphogypsum (radium enriched
industrial waste) and dissolution and weathering of the exposed piles where this radium enriched waste was stored.
In 1998 the waste management policy for industries changed. The direct discharges stopped and the new
phosphogypsum piles were well protected against dissolution processes, avoiding any transference of radium into the
environment. This work presents a study of the evolution with time (1999–2002) of the levels of 226Ra in river water
and sediment samples with the new waste management policy. A liquid scintillation technique was used to measure
the 226Ra activity concentration in sediment samples. A gas-proportional counter was also used to measure the 226Ra
activity concentration in river water samples. The main conclusion is that a systematic and continuous decrease of
the activity concentration of 226Ra with time in the Odiel River estuary is occurring. Thus, a possible self-cleaning in
the estuary, once the direct waste discharges were avoided, can be inferred. | es |
