“…During and for many years after the fallout, plants incorporate radionuclides through their roots. Comar and Wasserman [11] and Twardock et al [48] have estimated that about 1% of the strontium present in forage is transferred into milk. Other studies estimated that 4-6% of strontium intake from a contaminated diet appear in cow milk [53].…”

“…For goat milk Comar and Wasserman [11] and Twardock et al [48] observed a substantial difference between spiked strontium (66% for extraction yield) and metabolic strontium (86% for extraction yield) by using the ion exchange method. That difference may be explained by a greater concentration of calcium in goat milk than in bovine milk.…”

-This paper presents a review on all available analytical methods for 90 Sr and 89 Sr determination in milk. Special attention was focused on the parameter of the performing time in order to assess the rapid measurement of milk contamination, especially in the case of emergency situations such as a nuclear plant accident. Preliminarily, a short description of the milk matrix and radiostrontium transfer from soil to milk and its derivatives is given. Then analytical procedures are examined step by step. 90 Sr and 89 Sr can be separately determined in less than 2 days by a rapid sample pretreatment and the use of a liquid scintillation detector.Strontium / radioactivity / analytical method / milk Résumé -Revue des méthodes de dosage du radiostrontium dans le lait. Cet article présente l'ensemble des méthodes analytiques disponibles pour le dosage du 90 Sr et du 89 Sr dans le lait. Cette étude attache une importance toute particulière à la durée d'analyse dans le but d'une estimation rapide de la contamination du lait telle qu'elle est rendue nécessaire dans le cas de situations d'urgences comme l'accident d'une centrale nucléaire. En préliminaires, une rapide description de la matrice lait et du transfert du radiostrontium du sol au lait et ses dérivés est donnée. Puis, les procédures analytiques sont examinées étape par étape. Les isotopes 90 et 89 du strontium peuvent être déterminés séparément en moins de 2 jours par un traitement rapide de l'échantillon et l'utilisation d'un détecteur à scintillation liquide.

“…Only 50% of the natural strontium in milk is exchangeable at normal pH and for that reason the removal of Sr from milk labelled in vitro can be expected to be slightly higher than when labelled in vivo [10,19]. This, coupled to the fact that clinoptilolite is more selective for Cs than for Sr, shows that the use of clinoptilolite for the decontamination of milk is more suited for the removal of Cs than for Sr, although part of the latter is also removed in the process.…”

A number of inorganic ion exchangers were evaluated for their ability to remove Cs and Sr from milk. The synthetic exchangers titanium phosphate, zirconium phosphosilicate and sodium titanate or combinations of these removed up to 95% of the Cs and 54% of the Sr. Disadvantages of the use of these compounds were their high cost and the large pH change of the milk caused by the treatment. Natural zeolitic samples with high clinoptilolite content removed more than 90% of the Cs and 25% of the Sr without changing the pH. The composition of the treated milk was within the ranges normally found for milk from different sources. A trained tasting panel found the treated milk to be suitable for human consumption.
