Radioactive emissions into the atmosphere from damaged reactors of Fukushima Dai-ichi nuclear power plant (NPP) started on March 12th, 2011. Among various radionuclides released, iodine-131 ((131)I) and cesium isotopes ((137)Cs (134)Cs) were transported across Pacific toward North American continent reached Europe despite dispersion washout along route contaminated air masses. In Europe, first signs releases detected 7 days later while peak activity level was observed between 28th 30th. Time...
The influence of arbuscular mycorrhizal fungus on 134Cs uptake by Helianthus annuus was studied in a pilot study under growth chamber conditions. Mycorrhizal plants took up five times more (up to 250,000 Bq kg-1 dry weight) than non plants. Silver and titanium nanoparticles, supplied into the surface soil layer decreased both colonization Cs application activated carbon attenuated effect nanoparticles increased presence fungi 400,000 weight). results underline possible phytoremediation...
Abstract The radioactive fission product 90 Sr has a long biological half-life (˜18 y) in the human body. Due to its chemical similarity calcium it accumulates bones and irradiates bone marrow, causing high radio-toxicity. Assessing is therefore extremely important case of nuclear disaster. In this work 16 soil samples were collected from exclusion zone (<30 km) earthquake-damaged Fukushima Daiichi power plant, measure activity concentration using liquid scintillation counting. 137 Cs was...
Significance A massive atmospheric release of radioactive 106 Ru occurred in Eurasia 2017, which must have been caused by a sizeable, yet undeclared nuclear accident. This work presents the most compelling monitoring dataset this release, comprising 1,100 and 200 deposition data points from Eurasian region. The suggest reprocessing facility located Southern Urals, possibly Mayak complex. crashed satellite as well on Romanian territory (despite high activity concentrations) can be excluded....
Abstract ITER is of key importance in the European fusion roadmap as it aims to prove scientific and technological feasibility a future energy source. The EUROfusion consortium labs within Europe contributing preparation exploitation operation aspires exploit outcomes view DEMO. paper provides an overview major progress obtained recently, carried out frame new (initiated 2021) work-package called ‘ Pr eparation I TER O peration’ (PrIO). directly supported by eleven PrIO contributions given...
The therapeutic radionuclide 47Sc was produced through the 48Ca(p,2n) channel on a proton beam accelerator. obtained results show that optimum energies are in range of 24–17 MeV, giving possibility to produce containing 7.4% 48Sc. After activation, powdery CaCO3 target material dissolved HCl and scandium isotopes were isolated from targets. performed separation experiments indicate that, due simplicity operations chemical purity best process is when radioisotopes separated 0.2 µm filter.
Abstract Cryoconite granules are mixtures of mineral particles, organic substances and organisms on the surface glaciers where they decrease ice albedo responsible for formation water-filled holes. The contaminants effectively trapped in cryoconite stay there many years. This study evaluates contamination level artificial natural radionuclides holes from Adishi glacier (Georgia) identifies sources based activity or mass ratios among radionuclides. Results revealed high concentrations fallout...
The Cosmic Ray Extremely Distributed Observatory (CREDO) is a newly formed, global collaboration dedicated to observing and studying cosmic rays (CR) ray ensembles (CRE): groups of minimum two CR with common primary interaction vertex or the same parent particle. CREDO program embraces testing known CRE scenarios, preparing observe unexpected physics, it also suitable for multi-messenger multi-mission applications. Perfectly matched capabilities, could be formed both within classical models...
Abstract The cross sections for the production of medically significant radioisotopes, including 68Ge, 69Ge, 66Ga, 67Ga, 72As and various radioimpurities produced in pure germanium crystal irradiated with 60 MeV protons, were measured. experiment utilized targets natural isotopic composition.&#xD; Irradiation was performed using a proton beam from AIC-144 accelerator at Institute Nuclear Physics, Polish Academy Sciences, Krakow. Gamma spectroscopy conducted high-purity (HPGe) detectors...
Sector inductively coupled plasma mass spectrometry is a versatile method for the determination of plutonium activities and isotopic compositions in samples containing this element at fallout levels. Typical detection limits 239 + 240Pu are 0.1, 0.02 0.002 Bq kg−1Pu sizes 0.5 g, 3 50 g soil, respectively. The application sector ICP-MS-based Pu determinations demonstrated studies sediment chronology, soil inventory depth distribution, provenance global versus local or regional sources. A core...
Traces of particulate radioactive iodine (131I) were detected in the European atmosphere January/February 2017. Concentrations this nuclear fission product very low, ranging 0.1 to 10 μBq m-3 except at one location western Russia where they reached up several mBq m-3. Detections have been reported continuously over an 8-week period by about 30 monitoring stations. We examine possible emission source apportionments and rank them considering their expected contribution terms orders magnitude...
Activity concentrations, inventories and activity ratios of (137)Cs, (238)Pu, (239 + 240)Pu (241)Am in soil profiles were surveyed the dry tundra adjoining proglacial zones glaciers at a High Arctic site on Svalbard. Vertical radionuclide activities determined up to 14-cm-thick sequences. Additionally, properties (pH, organic matter, texture, mineral composition sorption capacity) analyzed. Results obtained this study revealed large range concentrations fallout radionuclides from...
A low background gamma spectrometer with an Etruscan, 2500 years old lead shield and a muon veto detector were applied to study 22Na 7Be activity concentration in ground level air aerosol samples collected weekly over the 2003-2006 Kraków. Each sample was formed ca 100 000 m3 of passed air, two parallel ASS-500 high volume samplers. The results for 40K 137Cs are also presented reference comparison. Presented frequency distributions correlation between obtained discussed. confirmed seasonal...
From early April 2020, wildfires raged in the highly contaminated areas around Chernobyl nuclear power plant (CNPP), Ukraine. For about 4 weeks, fires spread and into exclusion zone (CEZ) came within a few kilometers of both CNPP radioactive waste storage facilities. Wildfires occurred on several occasions throughout month April. They were extinguished, but weather conditions by airborne embers smoldering led to new starting at different locations CEZ. The forest only completely under...
