The Fukushima-Daiichi nuclear accident (FDNA) released iodine-129 (15.7 million year half-life)and other fission product radionuclides into the environment in the spring and summer of 2011. 129 I is recognized as a useful tracer for the short-lived radiohazard 131 I, which has a mobile geochemical behavior with potential to contaminate water resources. To trace 129 I released by the FDNA reaching Canada, preaccident and post-accident rain samples collected in Vancouver, on Saturna Island and from the National Atmospheric Deposition Program in Washington State were measured. Groundwater from the AbbotsfordSumas Aquifer was sampled to determine the fate of 129 I that infiltrates below the root zone. Modeling of vadose zone transport was performed to constrain the travel time and retardation of 129 I. The mean preaccident 129 I concentration in rain was 31 3 10 6 atoms/L (n 5 4). Immediately following the FDNA, 129 I values increased to 211 3 10 6 atoms/L and quickly returned to near-background levels. However, pulses of elevated 129 I continued for several months. The increases in 129 I concentrations from both Vancouver and Saturna Island were synchronized, and occurred directly after the initial release from the FDNA. The 129 I in shallow ( 3 H/ 3 He age <1.4 years) Wassenaar et al. (2006) groundwater showed measurable variability through March 2013 with an average of 3.2 3 10 6 atoms/L (n 5 32) that was coincident with modeled travel times for Fukushima 129 I. The groundwater response and the modeling results suggest that 129 I was partially attenuated in soil, which is consistent with its geochemical behavior; however, we conclude that the measured variability may be due to Fukushima 129 I entering groundwater.

“…Comparing published results of contamination monitoring after Fukushima accident obtained in Serbia [27] and in neighbouring regions [28,29] which are up to 2.7±0.1 mBq m -3 in Serbia [27], in Greece 0.497 mBq m -3 [28] and 1.2 mBq m -3 in Austria [29] it may be concluded that the influence of routine emissions from a nuclear facility is the most significant exposure scenario in chronic exposure situations.

Article Highlights• A study of the impact of nuclear reactor RA in Vinca on its environment using Gaussian model • The total dose was modeled using dose factors • Meteorological data for the six-year period were used • Nuclear reactor RA could not affect the environment above the prescribed limit Abstract Research activities of Vinca Institite have been based on two heavy water research reactors: a 10 MW one, RA, and zero power, RB. Reactor RA was operational from 1962 to 1982. In 2010, spent fuel has been sent to the country of origin, and the reactor now is in decommissioning. During the operational phase of the reactor there were no recorded accidental releases into the environment, only operational ones. Results of the environmental impact assessment of the assumed emission of radionuclides from the ventilation of nuclear reactor "RA" in Vinca to the atmospheric boundary layer are presented in this paper. Evaluation was done by using the Gaussian straight-line diffusion model and taking into account characteristics of the reactor ventilation system, the assumed emission release of radioactivity (from the literature), site-specific meteorological data for six-year period and local topography around nuclear reactor, and corresponding dose factors for inventory of radionuclides. Based on the described approach, and assuming that the range of appropriate meteorological data for six year period for the application of described mathematical model is enough for this kind of analysis, it can be concluded that the nuclear reactor RA, in the course of its work from 1962 to 1982, had no influence on the surrounding environment through the air above regulatory limits.

“…Furthermore, traces of the volcanic clouds could also be detected in the stratosphere over Western Siberia [9]. In March-April 2011, due to the Fukushima Daiichi nuclear disaster (Japan), radioactive materials were transported in the atmosphere over the Pacific Ocean [13][14][15] causing measurable concentration even in Europe [16][17][18] within a few weeks in several countries like Greece [19], Germany [20], and Serbia [21]. In April 2015 the plumes from the Calbuco volcano in Chile rising to 15-23 km height [22,23] reached Argentina and Uruguay [24] and influenced even the development of the Antarctic ozone hole in 2015 [25].…”

Large-scale atmospheric pollutant spreading via volcano eruptions and industrial accidents may have serious effects on our life. However, many students and non-experts are generally not aware of the fact that pollutant clouds do not disperse in the atmosphere like dye blobs on clothes. Rather, an initially compact pollutant cloud soon becomes strongly stretched with filamentary and folded structure. This is the result of the chaotic behaviour of advection of pollutants in 3-D flows, i.e., the advection dynamics of pollutants shows the typical characteristics such as sensitivity to the initial conditions, irregular motion, and complicated but well-organized (fractal) structures. This study presents possible applications of a software called RePLaT-Chaos by means of which the characteristics of the long-range atmospheric spreading of volcanic ash clouds and other pollutants can be investigated in an easy and interactive way. This application is also a suitable tool for studying the chaotic features of the advection and determines two quantities which describe the chaoticity of the advection processes: the stretching rate quantifies the strength of the exponential stretching of pollutant clouds; and the escape rate characterizes the rate of the rapidity by which the settling particles of a pollutant cloud leave the atmosphere.
