APPLICATIONS OF THE NOBEL GASES

1.                  Helium is used in weather balloons, in welding and in traffic signal lights.

2.                  A mixture of 80% helium and 20% oxygen is used for breathing by the sea drives.

3.                  Helium is used as a cooling medium for nuclear reactors.

4.                  Neon is largely used in making neon advertising signs, in high voltage indicators and TV tubes.

5.                  Neon and helium arc is used in making glass lasers.

6.                  Argon is used in electric light bulbs, in fluorescent tubes, in radio tube, and in Geiger counters (used to detect radioactivity).

7.                  Argon is also used for arc welding and cutting.

8.                  Krypton is used to fill fluorescent tubes and in flash lamps for high speed photography.

9.                  Xenon is used in bactericidal lamps.

10.              Radon being redioactive is used in radiotherapy for cancer, and for earth quake prediction.
