A metallic element occurring in various compounds in certain minerals, seawater, and marine plants.
A radioactive variety, strontium 90, is produced during nuclear reactions and may be present in nuclear fallout.
Strontium 90 accumulates in bone, where the radiation it emits may cause leukaemia and/or bone tumours.
Other forms of radioactive strontium have been used to diagnose and treat bone tumours.
n. a yellow metallic element, absorption of which causes bone damage when its atoms displace calcium in bone. The radioactive isotope strontium-90, which emits beta rays, is used in radiotherapy for the *contact therapy of skin and eye tumours and in *radioimmunotherapy in combination with *monoclonal antibodies. Another isotope, strontium-89 (Metastron), has an established role in the treatment of metastatic carcinoma: it is given by intravenous injection for the relief of pain due to bone metastases. Symbol: Sr.
Ethylenediamine tetra-acetic acid is used to treat poisoning with metals such as lead and strontium. One of the CHELATING AGENTS, EDTA is used in the form of sodium or calcium salts. The stable chelate compounds resulting from the treatment are excreted in the urine.... edta
