Measurement of 90Sr in Chernobyl arthropods
Ormaasen, Ivar (Master thesis, 2021)Following the Chernobyl accident, the areas around the Chernobyl Nuclear Power Plant (ChNPP) were contaminated with many radionuclides, including the fission product 90Sr. Because of its long half-life and chemical similarity ... -
Reduced bioavailability of Au and isotopically enriched <sup>109</sup>Ag nanoparticles transformed through a pilot wastewater treatment plant in Hyalella azteca under environmentally relevant exposure scenarios
Kühr, Sebastian; Kaegi, Ralf; Raths, johannes; Sinnet, Brian; Kipf, Marco; Rehkämper, Mark; Jensen, Karl Andreas; Sperling, Ralph A.; Ndungu, Kuria; Georgantzopoulou, Anastasia (Peer reviewed; Journal article, 2024)Wastewater Treatment Plants (WWTP) are a major repository and entrance path of nanoparticles (NP) in the environment and hence play a major role in the final NP fate and toxicity. Studies on silver nanoparticles (AgNP) ... -
Seasonal changes in uptake and depuration of 137Cs and 90Sr in silver Prussian carp (Carassius gibelio) and common rudd (Scardinius erythrophthalmus)
Teien, Hans-Christian; Kashparova, Olena; Salbu, Brit; Levchuk, Sviatoslav; Protsak, Valentyn; Eide, Dag Markus; Jensen, Karl Andreas; Kashparov, Valerii (Peer reviewed; Journal article, 2021) -
Speciation and source identification of radiocesium by radiochemical separation and QQQ-ICP-MS analysis
Hov, John Sebastian (Master thesis, 2021)The Fukushima Daiichi Nuclear Power Plant (FDNPP) accident on March 11th, 2011, in Japan caused the release of radioactive fallout, including radioactive cesium (Cs), and contaminated the near field but also large areas ... -
Speciation of key NORM nuclides in natural waters
Tryti, Johan (Master thesis, 2021)Naturally occurring radioactive materials are present everywhere in nature. These may cause harm to organisms. Therefore, it is important to know of their behaviour in the environment. The total concentration of an element ... -
Tracing simultaneous cadmium accumulation from different uptake routes in brown crab Cancer pagurus by the use of stable isotopes
Wiech, Martin; Amlund, Heidi; Jensen, Karl Andreas; Aldenberg, Tom; Duinker, Arne; Måge, Amund (Journal article; Peer reviewed, 2018) -
Transfer of strontium in the potato plant, solanum tuberosum L., following single foliar wet deposition : field experiments performed in Eastern Norway and at the West Coast of Norway
Østmoe, Stine (Master thesis, 2020)90Sr is one of the most important and frequent radioactive products from nuclear fission. If ingested, it is considered a major hazard to humans due to high retention in skeleton, leading to irradiation of cells and cancer ... -
Utlekking av metall frå Leca Lettklinker
Gjengedal, Elin; Vollset, Marie; Jensen, Karl Andreas (MINA fagrapport;40, Report, 2017)To typer Leca (Light Expanded Clay Aggregate) Lettklinker, utgangspunkt for biofilter til reinsing av gråvatn, er undersøkt med omsyn på utlekking av metall i kontakt med ionefritt vatn og vatn bufra til pH 4,0. Utlekk av ...
