Every industrially developed nation makes use of ionising radition:

· Between %15 and %20 of the world’s electricity comes from nuclear energy.

· Much of the world’s equipment for cancer therapy and medical imaging relies upon radiation techniques.

· The qualities of steeli coal and oil-bearing rocks are routinely measures using radiation.

· Radiation has proved indispensable for improving agricultural programmes (such as controlling parasites and improving crop yields)

· Techniques employing radiation are daily increasing our knowledge in the Physical and Life Sciences.

In short, radiation has been harnessed in many ways to improve our quality of life.

But uncontrolled, radiation poses a threat to health. Therefore extremely high standards of safety must be followed whenever radioactive materials are used.

Of absolutely key importance here is the continuous monitoring of designated controlled aeras where radioactive materials are used.

This is achieved using special instruments which must be highly sensitive, reliable and always suitable for their purpose.
