Measurements on environmental radioactivity at the Ispra site, 1994
In this report there are reported the measurements of environmental radioactivity performed during 1994 by the Radioprotection Unit of the Joint Research Centre Ispra Establishment, in charge for the site surveillance during 1994. A brief introduction about the description of the type of samples, the frequency of sampling, the chemical treatment, the instruments used for the measurements and the statistics for analysing data are reported. Data are given on the concentrations of some radionuclides (Sr-90, Cs-137, HTO and others) in precipitation, air, waters, herbage, milk, fish and radioactive effluents. The presence of low contamination in the environments is still a consequence of the nuclear accident in Chernobyl in 1986 and of the fall-out due to nuclear experiments in the atmosphere performed around 1960. The possible doses to the population are due to these causes, since the radioactive effluents discharged by the Establishment in the environment during 1994 are similar in quantity and isotopic composition to those of the previous years and imply a negligible effective dose equivalent.
