“…In this sense Sr would be held in the soil, but once adsorbed it would need to desorb as part of the soil exchange process before becoming available to be taken up by plant roots. Studies have shown that both clay and organic matter inhibit the transfer of soil Sr to plants (Baes et al, 1986; Lembrechts, 1993). Other complicating factors include the presence of competing ions in the soil (e.g., Na 2+ ), the concentration ratio of Sr to other micro- and macro-nutrients, and microenvironments (including ion depletion) created in the rooting zone by the plants themselves, all of which combine to render the concept of “bioavailability” difficult to operationalize within a given context (Ehlken and Kirchner, 2002).…”

We report on strontium (87Sr/86Sr) isotope results from 91 modern trees growing on the Bahamas and Turks and Caicos Islands. The average87Sr/86Sr ratio of 0.709169±0.000010 is consistent with the late Quaternary limestone of the islands and with the modern ocean value. The absence of any detectable influence of87Sr-enriched Saharan dust is notable, given the known contribution of this material to both past and recent soils of the Caribbean. Our results indicate that the impact of Saharan dust to the modern biosphere of the Bahamian archipelago is at least an order of magnitude less than modeled in currently available strontium isoscapes for the circum-Caribbean. We suggest that the bioavailability of Sr in Saharan dust may be considerably less than previously thought. Nevertheless, further work could usefully be carried out in the Bahamian archipelago on plants with different rooting depths, growing on different soil types and on limestone of different ages. Our results have particular relevance for the refinement of existing strontium isoscapes and the archaeological provenience of artifacts, animals, and people in the circum-Caribbean.

“…Since the Three Mile Island accident, much attention has been given to accidents that could take place at nuclear facilities which would result in radioactive releases to the environment in excess of acceptable levels[10]. The majority of accidents necessitate an off‐site response[11, 12,13,14 ,15,16,17 ,18]. However, our data had indicated that a borax accident that could occur in the Tammuz 2 reactor would give a maximum dose equivalent of less than 5 mSv, which is the annual dose limit for the exposure from all exposure pathways during normal situations[19].…”

The radiological consequences on the population of a borax accident in 1994 in the Tammuz 2 nuclear reactor have been postulated. Dose equivalents resulting from the atmospheric release of radionuclides during the accident have been estimated for distances ranging from the exclusion zone to 100km from the reactor. Gamma submersion, beta submersion doses from the plume, inhalation doses and surface exposure doses have been estimated for various exposure times. Dose equivalents estimated for the site boundary for an exposure time of 24 hours were 1.42 − 10mSv. Accordingly, it seemed that the consequences of the accident on the population living around Tuwaitha site could only take the form of stochastic radiation, such as the induction of cancers, and heredity.
