Question

State two dissimilarities between the γ-rays and X-rays.

Answer 1

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.
