Sodium-24 being a beta radiator may potentially be harmful to animal and humans if ingested or directly injected into the bloodstream. However having a short life span of roughly 15 hours, Sodium-24 does not pose a direct threat to any humans or animals.

use of sodium Of the radioactive artificial isotopes, sodium-22 (2.6-year half-life, the longest half-life of a sodium isotope) is used as a radioactive tracer for natural sodium. Sodium-24 (15-hour half-life) is limited in use by its short life and is produced by irradiation in a nuclear reactor.

Sodium-22 is a stable isotope containing 11 neutrons. Only trace amounts of sodium-22 are found naturally. Sodium-22 is a radioactive isotope which decays into 22Ne by β+ decay. Its half-life is 2.6 years.

Sodium 24 is used as an electrolyte tracer to follow the path sodium takes in a person’s body to see if their uptake levels are within normal ranges, while sodium 22 is used in nuclear medicine imaging for positron emission tomography. Sodium -24 can also be used in non-medical applications.

Sodium is ordinarily quite reactive with air, and the reactivity is a function of the relative humidity, or water-vapour content of the air. The corrosion of solid sodium by oxygen also is accelerated by the presence of small amounts of impurities in the sodium.

Sodium (Na) is an element in group 1 of the periodic table of the elements. Valence electrons determine many of the properties of an element, so elements in the same group have similar properties. All the elements in group 1 have just one valence electron. This makes them very reactive.

Sodium is used in the production of titanium, sodamide, sodium cyanide, sodium peroxide, and sodium hydride. Liquid sodium has been used as a coolant for nuclear reactors. Sodium vapor is used in streetlights and produces a brilliant yellow light. Sodium also forms many useful compounds.

Function. The body uses sodium to control blood pressure and blood volume. Your body also needs sodium for your muscles and nerves to work properly.

Sodium is both an electrolyte and mineral. It helps keep the water (the amount of fluid inside and outside the body’s cells) and electrolyte balance of the body. Sodium is also important in how nerves and muscles work.

What are the symptoms of low sodium levels? Hyponatremia occurs when sodium levels in the blood are too low. Symptoms include lethargy, confusion, and fatigue. It can result from underlying conditions, such as kidney failure, or other factors, such as drinking too much water or taking certain medications.

Food Sources of Sodium

Bananas, like most fruits and vegetables, are high in potassium and low in sodium. We humans get much of our dietary sodium from sodium chloride, otherwise known as salt.

But a new study finds that by increasing plain water consumption, we can control our weight and reduce intakes of sugar, sodium and saturated fat. Share on Pinterest Drinking more water is associated with reduced intakes of sugar, sodium and saturated fat, researchers say.

The sodium in milk is naturally-occurring and is present in small amounts. One cup of milk (250 ml) contains approximately 120 mg of sodium. This is less than 5% of the daily value for sodium (%DV).

Salty Six: Foods with Surprising Amounts of Sodium

• Processed meats. These tasty cuts are the primary source of sodium in the American diet.
• Pizza and pasta sauces. The low-sodium product choices for your favorite homemade pizza and pasta dishes are expanding all of the time.
• Bread.
• Soup.
• Salt seasonings.
• Chicken.

As a general guideline, 10% DV (230 mg) or less of sodium per serving is considered low, and 40% DV (920 mg) or more of sodium per serving is considered high.

Coconut milk, though, often has less than 15mg of sodium per serving and can be found in both canned and carton form.
