“…Maximum permissible ingestion levels for strontium are very low, because the radioisotope may negatively influence health. Exposure to 90 Sr can be examined by urine analysis with the use of sensitive analytical methods [3,6].…”

Radiation Protection Measurements Laboratory (RPLM) of the Institute of Atomic Energy POLATOM determines radionuclides in human urine to estimate the effective dose. Being an accredited laboratory, RPLM participated in interlaboratory comparisons in order to assure the quality of services concerning monitoring of internal contamination. The purpose of the study was to examine the effect of interlaboratory comparisons on the accuracy of the provided measurements. The results regarding tritium (3 H) and strontium (90 Sr) determination, obtained within the radiotoxicological intercomparison exercises, organized by PROCORAD, in 2005-2010, were analyzed and the methods used by the laboratory were verified and improved.

“…Nevertheless, Sr 2+ ionic strength was high in adsorbate of strontium solution. In order to obtain an accurate result of 90 Sr through the Cerenkov radiation measurement, one of the extractors is bis (2-ethylehexyl) hydrogen phosphate acid (HDEHP), employed to separate 90 Sr by Mosqueda et al 2 . But the separate process of 90 Sr was not clear; the efficiency of Cerenkov counting was sensitive.…”

The adsorption of Sr 2+ from solution with low concentration onto dried Ca-alginate was investigated in batch system. The adsorption dynamics, thermodynamics and effects of pH on Sr 2+ sorption capacity were carried out and the energy parameters of adsorption were computed. The results show that the adsorption of Sr 2+ onto dried Ca-alginate was rapid and low temperature was in favour of adsorption. The adsorption was considered a spontaneous exothermic process. The capacity of adsorption reaches the maximum when pH was 7. The energy parameters and electronic property of system have discovered that the MM block has the best adsorptive effect of Sr 2+ in all three kinds of blocks.

Strontium has several radioactive isotopes, with 90 Sr being the most important in the environment. This radionuclide dispersed worldwide as a consequence of the atmospheric nuclear weapon tests in the 1960s, and is locally enhanced owing to the accidents involving radioactive material. 90 Sr is a pure β‐emitter and it may be detected by several detection techniques (gas‐flow proportional, liquid scintillation, Cerenkov counting, and ICP‐MS), after an appropriate radiochemical separation. The environmental behavior of radiostrontium is governed by its chemical similarities to calcium. It is usually associated with the mobile and bioavailable fractions in soils, and with the low MW fraction in aquatic ecosystems. The potential human exposure to radiostrontium is mainly due to the ingestion of food, milk and cereals being the two major sources. This exposure can be reduced to some extent by the addition of calcium fertilizers to minimize the soil‐to‐plant transfer of radiostrontium, and by increasing cattle calcium intake to decrease the 90 Sr content in milk.
