Question

Ionizing radiations include:

  1. X- rays.

  2. Alpha rays.

  3. Gamma rays.

  4. All of the above.

hintHint:

Ionizing radiations have short wavelength.

The correct answer is:

X- rays.


    • Ionizing radiations are electromagnetic radiations 
    • They have the capacity to ionize an atom by removing an electron 
    • The ionizing radiations have shorter wavelength but high energy
    • X-rays, UV rays, gamma rays are all ionizing radiations
    • The ionizing radiations are classified under physical mutagens
    • Ionizing radiations induce mutations by introducing DNA breaks or by generation of reactive oxygen species like hydroxyl radicals

    • Mutagens are the factors that cause mutation
    • Physical mutagens include ionizing radiations, high concentration of carbon dioxide, etc
