radioactive sodium

radioactive sodium

Any of the radioactive isotopes of sodium, the most stable of which is positron-emitting 22Na, which has a half-life of 2.6 years. 22Na can be produced in a particle accelerator and may be used in nuclear medicine imaging and positron emission tomography (PET). 24Na has a 15-hour half life, quantification of which is used to determine the absorbed radiation dose of a patient exposed to intense neutron flux.

Should any children play in the creeks or swim in the Nolichucky downstream of NFS, they would be subjected to Americium-241, Cesium-137, Neptunium-237, radioactive sodium and lead, Radium-224, Technetium-99, 5 isotopes of uranium, 4 of thorium, and 4 isotopes of plutonium--a veritable bath of poisons.

Thyroid tumors that are too large or invasive to remove with surgery usually respond well to treatment with radioactive sodium iodide, which is an alternative to external beam radiation.
In the March 1972 issue of Health Physics, under the innocuous title "Effect of Na-22 on a Phospholipid Membrane;' he described how he found that cells that had withstood radiation doses as large as tens of thousands of rads without breaking ruptured at less than one rad when subjected to low-intensity, protracted radiation from mildly radioactive sodium salts.
