The determination of strontium-90 in environmental materials by ion exchange and preferential chelation techniques.
A method for determining strontium 90 in environmental materials is described. It consists of the ion-exchange separation of strontium from calcium at an elevated temperature by careful control of pH and the molar ratio of Ca:EDTA, followed by scavenging, Activity of the Sr-90 is determined by counting the yttrium 90 daughter. Recovery of strontium is determined with Sr-85 tracer. Typical recov...

متن کاملStrontium-89 Therapy in Painful Bony Metastases
Strontium-89 (Sr), a bone-seeking radiopharmaceutical, has been used successfully in recent trials to palliate bone pain secondary to metastatic disease. The use of this beta emitter in systemic radionuclide therapy should become an integral part in the management of many patients with metastatic disease to the bone. Intravenous Sr may be used in conjunction with standard chemotherapy and exter...

ness of a volume that attempts to construct too many bridges to too many of these interesting sites of investigation. The first section is concerned with melanin and is well done, especially the chapter by J. I. Harris on the chemistry of MSH, which is really an abbreviated primer on peptide "amino-acid sequence analysis." Brunet's chapter on melanogenesis is interesting and contains, in a note...
متن کاملSearch for Strontium-90 in Deciduous Teeth*
Contamination maps do not exist ; at best, strontium measurements are carried out sporadically by individual research groups. Furthermore, strontium is not at all looked for in the foodstuffsdatabase, which is used to calculate the radiation exposure of the population through taking in contaminated food. But it is known that relevant amounts of radioactive strontium were found in the teeth and ...
