, 2021 The 90Sr (T1/2 = 28.8 y) is a pure beta emitter radioisotope, produced by the fission of U and Pu isotopes. Low level (some Bq/kg or mBq/kg) 90Sr contamination exists in different environmental matrices as a result of nuclear weapon tests and nuclear ...

Determination of low-level 90Sr in large volumes of seawater
The release of radioactive substances into the environment, particularly the discharge of contaminated water from the Fukushima Daiichi Nuclear Power Plant, has raised public concern. 90Sr, a highly hazardous radionuclide, remains a significant challenge

90Sr and 137Cs in pilchards from the Adriatic Sea [PDF]
, 1993 Prikazani su i razmotreni biološki koncentracijski faktori za sustav srdele/morska voda za 90Sr i 137Cs. Koncentracijski faktor za 90Sr je konstantan, dok je koncentracijski faktor za 137Cs i dalje u porastu nakon nuklearne nesreće u Černobilju. UNSCEAR-

Radionuclide 90Sr Volume Activity Variations at the Baltic Sea Coast near Juodkrante [PDF]
, 2011 As far as radionuclide 90Sr volume activity (VA) after the Chernobyl Power Plant accident in the Baltic Sea increased negligibly, so the self-purification process from it was very slow. Long-term measurements of VA of 90Sr were carried out in 2004 at the

90Sr i 137Cs u srdelama Jadranskog mora
Arhiv za higijenu rada i toksikologiju, 1994 The biological concentration factors for the system pilchard/sea-water for 90Sr and 137Cs are presented and discussed. The 90Sr concentration factor was constant, whereas the concentration factor for 137Cs steadily increased after the Chernobyl accident. An UNSCEAR model was used to describe 90Sr transfer from fallout deposition to pilchards.

Contribution to analytical procedure for determination of 90Sr in urine and its present concentration [PDF]
, 1976 Opisana je metoda za detekciju 90Sr u mokraći, bez mokrog spaljivanja. Prvobitna koncentracija vrši se taloženjem fosfata, a daljnja analiza ekstrakcijom TBF. Kemijsko iskorištenje stroncija dobiveno je fotometrijom plamena i dodavanjem 85Sr te mjerenjem

A new application of mass spectrometry instruments,90Sr analysis
, 2018 Five isotopes of strontium element exist in the environment, four of them (84Sr, 86Sr, 87Sr, 88Sr) are stable and have natural origin while 90Sr is a radioactive isotope (T1/2=28.8 y) and originates from nuclear weapon tests and nuclear accidents.
