“…The maximum concentrations of 134 Cs and 137 Cs in plants (on a fresh weight basis) on the Sakhalin and Kuril Islands in 2011 were 5 and 18 Bq/kg, respectively [ 16 ]. The results of environmental radioactivity studies and assessments of radiation doses to humans and biota were recently summarised in the comprehensive review book entitled “Fukushima Accident: 10 years after” [ 17 ].…”

This paper presents research on the assessment of the radioecological state of plant cover surrounding two research reactor facilities located within the Semipalatinsk Test Site (STS) as examples of nuclear fuel cycle facilities (NFC). Source data on the concentrations of artificial radionuclides in the plant cover were obtained. Quantitative values for 137Cs, 241Am, and 239+240Pu activity concentrations were determined in plants across the perimeters of the facilities, indicating that these compounds may be present in the associated media from the perspective of accumulative bioindication. The values determined for artificial radionuclides in the ‘soil‒plant’ system around the researched NFC facilities were attributed to radioactive contamination of the STS territory.

“…In March 2011, an exceptionally strong earthquake and the consequent tsunami waves struck the eastern coast of Honshu (Japan), causing severe damage to the critical systems of the FDNPP and eventually leading to a loss of ability to control and cool the shutdown reactors. Despite the enormous effort, hydrogen explosions, which emerged from the reaction of heated steam with nuclear fuel cladding, occurred in three out of four reactor buildings [ 1 ]. The total amount of released radionuclides from the FDNPP nuclear core inventories into the atmosphere was estimated to be 9.6 ± 3.4 EBq, comprising mainly short-lived fission products, such as 133 Xe and 131,133 I [ 2 ].…”

Impact of the Fukushima Accident on 3H and 14C Environmental Levels: A Review of Ten Years of Investigation

2023

The investigation of the impact of the Fukushima accident is still going on although more than ten years have passed since the disaster. The main goal of this paper was to summarize the results of tritium and radiocarbon determinations in different environmental samples, possibly connected with the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident. A document containing compiled data may serve as a solid basis for further research in the selected fields. To accomplish such effort, we went through dozens of relevant published papers, reporting 3H and 14C activity concentrations in precipitations, groundwater, seawater, river systems, tree rings, and, in some more extraordinary samples, such as herbaceous plants or debris from the damaged reactor buildings. As the referenced results would not be obtainable without adequate analytical techniques, the most common methods for routine measurement of tritium and radiocarbon concentrations are discussed as well. We believe that the correct identification of the affected environmental compartments could help quantify the released 3H and 14C activities and track their following fate, which could be especially important for plans to discharge contaminated water from the FDNPP in the upcoming years.
