The high boiling point of sodium allows the reactor to operate at ambient (normal) pressure, but the drawbacks include its opacity, which hinders visual maintenance, and its explosive properties. From the weight of the sodium salt and the volume of air in the room, we easily calculate that one part by weight of air could not contain more than 1/20 millionth weight of sodium.  Radioactive sodium-24 may be produced by neutron bombardment during operation, posing a slight radiation hazard; the radioactivity stops within a few days after removal from the reactor. They have 30-66% less sodium than regular table or sea salt. In medieval Europe, a compound of sodium with the Latin name of sodanum was used as a headache remedy. As calcium is less electropositive than sodium, no calcium will be deposited at the cathode. , The U.S. Institute of Medicine set its Tolerable Upper Intake Level for sodium at 2.3 grams per day, but the average person in the United States consumes 3.4 grams per day. Now let’s look at table salt, which is a combination of sodium and chloride. Sodium not only helps your body keep fluids in all the right places, but also aids in nerve conduction and helps your muscles work. With it’s bad rap, you may be surprised to learn that you can’t live without sodium.  Sodium spontaneously explodes in the presence of water due to the formation of hydrogen (highly explosive) and sodium hydroxide (which dissolves in the water, liberating more surface).  By itself or with potassium, sodium is a desiccant; it gives an intense blue coloration with benzophenone when the desiccate is dry. Sodium hydroxide is neutralized with hydrochloric acid to produce the soluble salt sodium chloride in solution.
