    The principle is that when a solution of ferrous sulphate contained in a quartz cell is exposed to ionizing radiation then Fe 2+ ions are oxidized to Fe 3+ ions, the concentration of the latter being proportional to the absorbed dose. Analytical grade chemicals and double-distilled water are used in the preparation of the standard Fricke solution:

    In water, ferrous sulfate salts are hydrolyzed, forming the aquo complex [Fe(H 2 O) 6] +2. By the other side, these salts lose water molecules when are in contact with the air. In humidity ambient, ferrous sulfate salts oxide to ferric sulfate. Uses: in medicine, ferrous sulfate is a supplement of iron in human body. Thus, it is used to treat anemia and it is suministrated to pregnant women as iron source.
