X-Ray Introduction :

The term X-Ray is derived from X-radiation. It is form of electromagnetic radiation. It has wavelength longer compare to Gamma rays and shorter compare to UV rays. It has following characteristics.

• Frequency range : 30 Petahertz to 30 exahertz ( i.e. 3 x 1016 to 3 x 1019 )
• Wavelength range : 0.01 to 10 nanometers
• Energy range : 100 eV to 100 KeV

Based on energy levels there are two types of X-rays viz. hard X-rays and soft X-rays. X-rays having higher photon energies are known as hard X-rays while the one having lower energies are known as soft X-rays. X-ray is one of the modern imaging techniques including ultrasound, CT scan and MRI which shows structure inside the human body.
