Strontium-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...
متن کاملSimulating the Transfer of Strontium-90 from Soil to Leafy Vegetables by Using Strontium-88
The transfer, from soil to Chinese cabbage and spinach, of radioactive strontium-90 released as a result of accidents in nuclear power stations was studied using a stable isotope of strontium, namely nuclide strontium-88 (88Sr). The study led to an experimental model for assessing the hazard of radionuclide strontium-90 (90Sr) entering the food chain and for predicting the risk to food safety. ...
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 ...
متن کاملComparison of strontium-89 solution sources in UK hospitals, 2003.
Concerns have been raised within the nuclear medicine field about the accuracy of measurements of 89Sr. The 85Sr impurity present in the 89Sr solution has a significant effect on the response of radionuclide calibrators used in hospitals. A comparison was conducted between the National Physical Laboratory (NPL) and the UK hospital physics community. Only 58% of the results were within 5% of the...
متن کاملStrontium-90 and intrauterine development in the rat.
It is well known that the developing mammalian embryo is sensitive to irradiation from external sources, causing developmental anomalies and lethal effects, and that this sensitivity can vary with stage of development (Hicks, 1953; Levy et al 1953; Fraser, Kalter, Walker & Fainstat, 1954; Russell & Russell, 1954; Warkany, 1954; Wilson, 1954; Rugh, 1963). Irradiation of the embryo prior to impla...
