Rubidium/Strontium and Strontium-87/Strontium-86 Ratios in Deep Crustal Material
Nature, 1964RECENT work on the strontium isotopes, stimulated by a paper of Gast1, has shown variations in the initial 87Sr/86Sr ratio of rocks. The interpretation of this observation has not been clear but it has been implied that ratios similar to those in basalts define an origin more or less directly from mantle material2–4. Higher ratios have been interpreted

Strontium and cardiovascular events
Annals of the Rheumatic Diseases, 2013In the report of their trial of strontium ranelate in knee osteoarthritis, Reginster and colleagues state ‘Strontium ranelate was well tolerated’, and ‘The safety profile of strontium ranelate was satisfactory, in line …

Previous skeletal irradiation from bone-deposited radionuclides does not seem to influence the metabolism of a Sr/sup 85/ tracer in beagles under the conditions, dose rates, and times studied. Confinement immediately after the injection of a Sr/sup 85/ tracer reduces Its retention.

Proceedings of the Indian Academy of Sciences - Section A, 1941
The specific magnetic susceptibility of strontium has been determined by the Curie method. The value at 30°C. is found to be +1·05×10−6. A thermomagnetic investigation of the metal showed the specific susceptibility to increase from 1·02×10−6 at 0°C. to 1·09×10−6 at about 65°C. The susceptibility decreased thereafter to +0·73×10−6 at 260°C.

Primeval Strontium-87/Strontium-86 Ratio
Nature, 1965IN a previous communication1 I described an attempt to estimate the initial concentrations and partition coefficients of rubidium and strontium. The calculation was performed based on two possible values of the slope of the line representing the abundance correlation between rubidium and strontium.

Strontium as therapy for osteoporosis
Current Opinion in Pharmacology, 2005Osteoporosis is characterized by low bone mass and increased susceptibility to fracture. Recent in vitro studies showed that strontium ranelate, a novel agent containing two strontium atoms, acts as an effective anti-osteoporotic drug by inhibiting bone resorption by osteoclasts and promoting osteoblast replication and bone formation.

Samples of bone and soil collected in 1958 show highest values for Sr 90 in the tropical region on the east side of the Andes. Lowest values are found in the high central valley, where samples used in estimating world-wide distribution of fallout were collected. If the major fallout deposition occurs in the interior

Sr, a member of alkaline earth elements (Group 2a in the periodic table) occupies in many chemical aspects an intermediate position between Ca and Ba. The atomic number is 38 and the atomic weight is 87.62. Sr occurs in nature chiefly as SrSO4 (celestite) although SrCO3 (strontianite) is also found in several areas of the world.

Chemical analysis of calcified skeletons has expanded rapidly during the past twenty-five years, undoubtedly because of advances in the general field of geochemistry and the development of more precise analytical techniques. This review and the following discussion are confined to that part of the subject that is of direct importance to the geologists ...
