Question
State two dissimilarities between the γ-rays and X-rays.
Advertisements
Solution
| Sr. No. | Property | γ-rays | X-rays |
| 1. | Origin | These rays originate from inside an unstable atomic nucleus during radioactive decay transitions. | These rays are produced outside the nucleus when high-velocity cathode electrons strike a heavy metal target. |
| 2. | Penetrating Power | These waves possess an extremely high penetrating power that can pass through thick iron plates. | These waves possess a much lower penetrating power compared directly to gamma rays. |
| 3. | Wavelength | These rays have a shorter wavelength, which gives them a higher energy level. | These rays have a longer wavelength, which gives them a lower energy level. |
