Fukushima fallout of 131I, 137Cs, 134Cs at Milano, Italy

131I and 137Cs and 134Cs fallout isotopes were measured in the Milano region (45\ub0N), Italy over one month after the nuclear accident in Fukushima, Japan. Daily monitoring of the airborne activity levels carried out with a high volume air sampler, gave increased atmospheric radioactivity on air filter taken on 30 March 2011, while the maximum activity of 467 \ub5Bq m-3, occurred at April 3-4, 2011. Radionuclides from Fukushima fallout were first detected at Milano region in a rain water sample, at 27-28 March, 2011 with the concentrations of 131I and 137Cs isotopes in the rainwater to be equal to 0.89 Bq L-1 and 0.12 Bq L-1, respectively. During the same days a snowfall sample was collected from Monte Rosa mountain at a height of 3000 m, with the concentrations of 131I and 137Cs in snowfall to be lower than that in rainwater sample. A sample of dry deposition that was collected 9 days after the first rainfall event of 27-28 March, 2011 showed that the dry deposition of 131I and 137Cs was 0.40 Bq m-2 and 0.24 Bq m-2 respectively. The concentration of 131I in goat and cow milk samples collected on 9 April, 2011 from a farm at a village in Anzasca valley near Macugnaga (Monte Rosa mountain), were 0.30 Bq L-1 and 0.37 Bq L-1 respectively
