Which of the following X-rays has the largest intensity?
Correct answer: A. Kα X-Ray
- A. Kα X-Ray
- B. Kß X-Ray
- C. Kγ X-Ray
- D. All of these option have the same intensity
Explanation
Alpha rays are the positively charged particles. Alpha-particle is a highly active and energetic helium atom that contains two neutrons and protons. These particles have the minimum penetration power and highest ionization power. They can cause serious damage if they get into the body due to their high ionization power. They are capable of ionizing numerous atoms by a short distance. It is due to the fact that they cause a great transition from n=1 to n(target) so they have higher intensity than others.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
