Abstract
The radioactive pollution in Sardinia, has been in the recent years matter of a considerable debat in the scientific literature. At the present time however, the complex problem of possible interaction between environmental and human activity in a long suitable period is still awaiting a adequate interpretation. At the end of 70 years, the Italian Nuclear AGIP survey has been carried out detailed researches on U ore deposits linked to the fast sedimentation processes in lacustrine environments associated to the post-collisional events during the paenipleining process of Sardinia chain. Particularly, researches focused on siltites and sandstones levels belonging to the post-collisional covers referred to the Permian-Carboniferous time span outcropping in several areas of Sardinia island. Collected data indicate important radioactive anomalies localized in Ogliastra and Sarcidano regions in the central and southern Sardinia. These areas are characterized by a high natural background radioactive values; suitable knowledge elements are offered by the comparison between data collected in the present work in the Escalaplano and Perdasdefogu areas with those of Nuclear AGIP during the 70¹ years. Further relationships between human activity and environment will be indicated by data collected on dental apparates because they record the interaction of the organism with pollutant substances. As a consequence, it is expected the possibility to reconstruct history and length of interaction processes with pollutant substances, because during the formation of dental germs the vascularisation favoured the mobility of chemical elements which successively are fixed in the mineral fraction of teeths. The scenario has reconstructed on account of a precise evaluation of human pollution and linked to the recent complex socio-economical history of investigated areas. Moreover, will be studied the human impact on environment to and the possible radioactive anomalies in the investigated areas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
