30 de ene. de 2017 · Strontium-90 (90 Sr) is a bone- and teeth-seeking radionuclide 1 that is released in large quantities during nuclear accidents and aerial nuclear testing 2,3,4. Due to its high solubility in water and long half-life (29 years), this radionuclide persists in the environment for a long time and progressively enters the food chain.
This step and 2M nitric acid wash allow separation of Sr-90 from such nuclides as Y-90, K-40, Co-60, and Cs-137. To increase strontium recovery, 6 mL of 0.2 M nitric acid was used for the final elution. Table 4 shows the results with the average strontium recovery of 93–94%.
Strontium. S.C. Gad, in Encyclopedia of Toxicology (Third Edition), 2014 Reproductive Toxicity. In a minipig study in which dams were dosed with strontium-90, levels required to affect fetal or neonatal mortality were high enough to kill the dams as well.Injection of pregnant mice with strontium-90 in one study caused a decrease in number of fetal oocytes as well as skeletal malformations.
