Journal of Food ProtectionFollowing the Fukushima Daiichi Nuclear Power Plant accident in 2011, concerns over radionuclide contamination in food, particularly radioactive cesium (r-Cs: 134Cs and 137Cs) and strontium-90 (90Sr), have persisted. While extensive studies have examined

The use of 90Sr/90Y generator for electrochemical separation of 90Y from 90Sr
, 2013 90Y is a radioisotope and decay product of 90Sr for therapeutic purpose due to its suitable half-life T1/2=64.1h. The half-life of 90Sr is longer (T1/2=28,9 years) and have a high skeleton uptake. To obtain a radionuclide with a high level of purity is necessary to separate 90Y from the bulk of 90Sr. The most promising approach to separate 90Y from the

Prediction model for 90Sr level in milk.
Arhiv za higijenu rada i toksikologiju, 1987 U radu je opisan model transfera 90Sr od radioaktivnih padavina do mlijeka koji je predložio UNSCEAR (1). Sakupljeni su podaci o aktivnosti 90Sr u radioaktivnim padavinama i mlijeku iz područja Zagreba. Model pokazuje vrlo dobro slaganje s empirijskim podacima i statistički značajnu povezanost između aktivnosti 90Sr u mlijeku i radioaktivnim padavinama

Optimization of 90Sr/89Sr measurements
EPJ Web of Conferences, 2012 One of the key points in the double measurement method for the measurement of both, 89Sr and 90Sr, by using a proportional counter is the choice of the times at which the measurements should be done.
