Applications
|
|
Sodium Iodide is used in photography and as an
analytical reagent. It is used in the measurement of the energy of gamma
rays, by measuring the amplitude of pulses of light generated by
electrons which are excited by the gamma rays.It is used as a nutrition
supplement to prevent goitre and other iodine deficiency in human
body.
