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....
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...
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...
The research was aimed at providing new knowledge in the field of chemical characteristics solid waste generated process combustion sewage sludge fluidized bed furnaces. material consisted disposed beds (DFB), ash (SSA) and air pollution control residues (APC) from three Polish installations for thermal treatment sludge. Natural radionuclides as well anthropogenic isotope
The measurements of the specific activity natural radioactive isotopes radium (226Ra), thorium (232Th) and potassium (40K) in chosen samples imported (China, Finland, Spain, India, Sweden) Polish (Izerski, Karkonosze, Siedlimowicki, Strzegomski, Strzelinski) granites were performed. carried out with 2 × 2" NaI(Tl) scintillation detector. measured on within following ranges: 5.8-312 [Bq kg-1], 5.5-189 kg-1] 109-1590 for 226Ra, 232Th 40K, respectively. Obtained concentrations allowed to...
Abstract The influence of uncertainty on the method adopted for determination radioactive radium concentration in water was analyzed due to assessment radiation hazards balneotherapy. For calculation, we considered bath containing only 226 Ra. Ra determined with two γ-spectrometers armed HPGe detectors different relative efficiencies. Both spectrometers were energy-efficiency calibrated a calibration source and based numerical simulations. Different methods qualitative γ-spectrum analysis...
In this article are presented the results of measurements natural radioactivity in twelve soil samples from Kampinoski National Park by using high purity germanium detector (HPGe). The average values radionuclides 40 K, 226 Ra and 228 Ac concentrations 8.54, 6.65 206 Bq/kg respectively. Additionally radiation hazard indices were calculated to evaluate radiological risk for public environment. show that mean radium equivalent activity (Raeq) gamma absorbed dose rate (D) air, outdoor annual...
Natural radioactivity is present in the human environment to a greater or lesser extent, also varioustypes of raw building materials. Monitoring concentration natural radioactive isotopesof potassium 40K, radium 226Ra and thorium 228Th 232Th samples and/or constructionmaterials allows assessing exposure people ionizing radiation emitted by these materials.Exceeding limit value index for materials,defined Ordinance Council Ministers (Polish Journal Laws/Dz.U. No. 33/2021),may result an...
This article presents the results of natural radioactivity research for selected building materials such as: ceramic blocks, cellular concrete, solid bricks, roof tiles, cement, mortars, plaster and adhesives available on domestic market. In Poland, possibility using various raw ready-made construction depends values activity coefficients f 1 2 . The coefficient determines content isotopes in examined material, as an indicator whole body exposure to gamma radiation. radium 226 Ra epithelial...
The Central Laboratory of Radiological Protection together with 30 other laboratories in Poland is involved the analysis radioactivity among indirect products combustion (ashes and slags) coming from polish power plants thermal station. Systematic studies are conducted on concentrations natural radioactive isotopes waste materials obtained industry, their results recorded a database. This database supervised by for Protection. already contains 46300 now oldest come eighties. In this article...
