title: Environmental radioactivity analyses in Italy following the Fukushima Dai-ichi nuclear accident.
abstract: Following the Fukushima power plants accident on the 11th March 2011, the radioactivity monitoring programme at the Italian ENEA research centres was activated in order to detect the possible new input of radionuclides through atmospheric transport and precipitation. Measurements of (131)I and (134,137)Cs were carried out on atmospheric particulate, atmospheric deposition, seawater and mussels and sheep milk. In the daily samples of air particulate, (131)I was detectable between March 28 and April 12, with extremely low concentrations (<1 mBq m(-3); the detection limit for (131)I was ~0.2 mBq m(-3)) while Cs isotopes were always below the detection limit (<0.2 mBq m(-3)). The two main episodes of (131)I atmospheric deposition were registered in La Spezia research centre, around March 28 and April 15, reaching values of 17.8 ± 1.1 and 8.0 ± 2.5 Bq m(-2) respectively; maximum values of (134)Cs and (137)Cs were 0.11 ± 0.03 and 0.17 ± 0.02 Bq m(-2), respectively, detected in Brasimone research centre in April (reference date April 15). Mussels and seawater were collected in the Gulf of La Spezia: only mussels after the main (131)I deposition, on March 28, contained a measurable, although very small, amount of (131)I (0.18 ± 0.05 Bq kg(-1), detection limit (131)I = 0.03 Bq kg(-1) wet weight - soft parts). The (131)I was also detected in sheep milk in Rome (Casaccia research centre) until May 5, showing a maximum concentration of 4.9 ± 0.4 Bq L(-1). As for other European Countries for which data are available, activity levels remain of no concern for public health.
