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...
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....
Direct links between carbonaceous chondrites and their parent bodies in the solar system are rare. The Winchcombe meteorite is most accurately recorded chondrite fall. Its pre-atmospheric orbit cosmic-ray exposure age confirm that it arrived on Earth shortly after ejection from a primitive asteroid. Recovered only hours falling, composition of largely unmodified by terrestrial environment. It contains abundant hydrated silicates formed during fluid-rock reactions, carbon- nitrogen-bearing...
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...
Abstract Results of nondestructive gamma‐ray analyses cosmogenic radionuclides ( 7 Be, 22 Na, 26 Al, 46 Sc, 48 V, 54 Mn, 56 Co, 57 58 and 60 Co) in 19 fragments the Košice meteorite are presented discussed. The activities varied mainly with position meteoroid body, fluxes cosmic‐ray particles space affecting different half‐lives. Monte Carlo simulations production rates Co Al compared experimental data indicate that pre‐atmospheric radius was 50 ± 5 cm. In two fragments, He, Ne, Ar...
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...
Abstract On February 15, 2013, after the observation of a brilliant fireball and spectacular airburst over southern Ural region (Russia), thousands stones fell were rapidly recovered, bringing some extremely fresh material for scientific investigations. We undertook multidisciplinary study dozen Chelyabinsk meteorite, including petrographic microprobe investigations to unravel intrinsic characteristics this meteorite. also short long‐lived cosmogenic radionuclides characterize initial...
In June 1976, a pristine meteorite stone weighing approximately 1 kg, fully covered with fresh black fusion crust, was collected on mountain road in the high-altitude Alpine environment. The recovery took place while clearing remnants of snow avalanche, 2 km northwest Ischgl Austria. Subsequent to its retrieval, specimen remained finder's private residence without undergoing any scientific examination or identification until 2008, when it brought University Innsbruck. sample classified as...
This evaluation of techniques, apparatus, and dedicated facilities for measurement very low levels radioactivity is addressed to the large community researchers who use radioactive tracers, make activation analyses, etc. may occasionally face problem measuring an activity well below level accessible with standard commercial equipment.Emphasis put on instrumental gamma-spectrometric assay complex mixtures radionuclides, spectrometric measurements alpha activities in relatively massive...
