Terahertz vs. X-ray: Key Differences and Applications

terahertz x-ray electromagnetic spectrum radiation imaging

This article explores the differences between terahertz (THz) and X-ray radiation, both of which reside on the electromagnetic spectrum and serve distinct purposes. While they share some similarities, key differences exist, which we’ll outline below.

Terahertz vs X-ray

Let’s delve into a detailed comparison, examining parameters like frequency, wavelength, radiation type, photon energy, advantages, disadvantages, and applications.

Difference between Terahertz and X-ray

The following table summarizes the key differences between terahertz and X-ray radiation:

FeaturesTerahertzX-ray
Frequency rangeLower than X-ray, 0.1 to 10 THz (1 THz equals 1×10121 \times 10^{12} Hz)Higher than Terahertz, 30 Petahertz to 30 Exahertz (i.e. 3×10163 \times 10^{16} to 3×10193 \times 10^{19} Hz)
Radiation typeNon-ionizingIonizing
Photon energyLowHigh
WavelengthLongerShorter
Advantages- Easily pass through non-conducting material - Higher bandwidth - Minimum effects on human body- Not absorbed very much by air - Diagnose tumors without the need of surgery - Used by radiologists to identify cracks - To identify abnormal bones etc.
Disadvantages- It cannot penetrate liquid water or metal - Does not support long-range communication due to atmospheric loss- Causes ionization and hence it often leads to cancer - Bones block significant diagnostic data as it absorbs radiation
Organic Material IDPossible using THz imagingNot possible using X-ray imaging
