Soft X-ray vs Hard X-ray: Key Differences Explained

x ray soft x ray hard x ray photon energy medical radiography

This article breaks down the key differences between soft X-rays and hard X-rays. Let’s dive in!

Soft X-Ray

  • Frequency: 30 to 3000 PHz
  • Wavelength: 10 to 0.1 mm
  • Photon Energy: Lower
  • Application: Commonly used in mammography

Hard X-Ray

  • Frequency: 3 to 300 EHz
  • Wavelength: 100 to 1 pm
  • Photon Energy: Higher, typically above 5 to 10 keV
  • Application: Versatile, used to image the insides of objects in applications like medical radiography, airport security, and determining crystal structures.

Key Differences Summarized

The main differences between soft and hard X-rays boil down to energy and wavelength:

  • Energy: Hard X-rays possess higher energy levels compared to soft X-rays.
  • Wavelength: Hard X-rays have shorter wavelengths, while soft X-rays have longer wavelengths.
