the harm which radiation has the potential to cause. However radiation is far more common than this applications and there are many positive applications such as the use of sodium
isotope-24 which is used to example the circulatory system. Sodium itself was discovered by Sir Humphrey Davy in England in 1807
(Barbalace, 2003). The name sodium comes from the English Soda and the chemical symbol Na from the Latin natrium (Barbalace, 2003, Emsley, 2002). The element is fairly abundant as it
makes up 2.6% of the earths crust. The element is obtained though electrolysis of melted sodium chloride, cryolite, and borax (Barbalace, 2003). The element looks like a soft silvery whit
powder and it is an alkali metal (Ball, 2003). The link between sodium and medical use was not new with the application of the isotope 24, it had already been
used in medieval times as a headache remedy. Looking at the chemical make up of sodium at room temperature the element is a
solid, boiling point is 1156 degrees Kelvin, 883 degrees Celsius or 1621 degrees Fahrenheit (Barbalace, 2003). The freezing point at which it becomes a solid is 371 Kelvin, 98 degrees
Celsius or 208 degrees Fahrenheit (Barbalace, 2003). The atomic mass average is 22.98977 (Barbalace, 2003). The density is 0.971g/cc at 300K,
the electrical conductivity is 0.21 106/cm (Barbalace, 2003). Looking at the chemical rather than the physical properties the electrochemical equivalent is 0.85775g/amp-hr and when looking at ionisation potential, mean
the minimum amount of energy required to remove the outermost electron from a neutron when the element in the gas state, the first is 5.139, the second is 47.286 and
