“…Gommers et al (2005) also informed that the TF from soil to oak trees wood varied from 0.001 to 0.457, and our results are within these limits. Our TF values for 137 Cs soil to different oak tree compartments ranged from 0.01 to 0.38 and the results are comparable with these reported by Al-Oudat et al (2006) for oak trees in arid regions, which suggests a relatively higher level of 137 Cs transfer toward oaks under these climatic conditions. The data obtained showed that the 137 Cs transfer was clearly expressed in the basis of the trunk.…”

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.
