Question

Beta particles produce , when they hit solid metals having high melting point, like gold.

• A. $\gamma$-rays
• B. X-rays
• C. cathode rays
• D. $\alpha$-rays

Answer 1

The correct option is B X-rays

$\beta$-particles are a stream of electrons produced from the nucleus of an atom, during the radioactive decay of an element. When these particles are obstructed by a metal having a high atomic number as well as a high melting point like tungsten or gold, they produce $\text{X}$-rays.
