Advantages of X-Ray | Disadvantages of X-Ray

This page covers advantages and disadvantages of X-Ray. It mentions X-Ray advantages and X-Ray disadvantages.

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.

Advantages of X-Ray

Following are the advantages of X-Ray:
➨It is cheaper and simple technique.
➨It has lower radiation compare to CT scan.
➨X-rays are not absorbed very much by air, hence specimen need not be in an evacuated chamber.
➨It helps to diagnose tumours easily without the need of surgery.
➨X-rays are widely used by radiologists to identify cracks, for infections, to identify level of injury, and to identify abnormal bones.
➨It helps to locate alien objects inside or around bones.

Disadvantages of X-Ray

Following are the disadvantages of X-Ray:
➨It does not provide 3D information.
➨Bones can block significant diagnostic data as it absorbs the radiation.
➨They do not interact very strongly with lighter elements.
➨Due to its radiation, it mutates cells which causes ionisation. This often leads to cancer.
➨It does not produce the best image but medium quality image.

Though X-rays are not 100% safe, they are very useful for diagnosis if used in safest and controlled environments as much as possible.
