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.
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:
| Features | Terahertz | X-ray |
|---|---|---|
| Frequency range | Lower than X-ray, 0.1 to 10 THz (1 THz equals Hz) | Higher than Terahertz, 30 Petahertz to 30 Exahertz (i.e. to Hz) |
| Radiation type | Non-ionizing | Ionizing |
| Photon energy | Low | High |
| Wavelength | Longer | Shorter |
| 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 ID | Possible using THz imaging | Not possible using X-ray imaging |
