Artificial radio nuclides, such as iodine-131 (131I), cesium-134 (134Cs) and cesium-137 (137Cs), as well as natural isotopes of beryllium-7 (7Be) and potassium-40 (40K) have been registered in atmospheric aerosols over Vladivostok selected from 11 March to June 17, 2011. Artificial radio nuclides were also discovered in atmospheric wet depositions. Variability of gamma activity of natural isotopes of 7Be and 40K is not greater than one order of magnitude throughout the sampling period. Synoptic analysis of back trajectories movement of air masses showed that the radioactive cloud came from the regions of Siberia and North-Eastern part of China.
