Hint:
The rays which are not included under electromagnetic spectrum.
The correct answer is: UV rays.
- Ionizing radiations are radiations capable of ionizing an atom by removing electrons
- Ionizing radiations are classified under physical mutagens
- X-rays, gamma rays and UV rays are the common examples
- These ionizing radiations have shorter wavelength but higher frequency
- Ionizing radiations are included under electromagnetic spectrum
