Explain with an example each nuclear transmutation and artificial radioactivity. What is the difference between them? |
|
Answer» i. Nuclear transmutation : It involves transformation of a stable nucleus into another nucleus takes place which can be either stable or unstable. ii. Artificial (induced) radioactivity : It is nuclear transmutation where the product nucleus is radioactive. The product nucleus decays spontaneously with emission of radiation and particles. e.g, Step I : \(_5^{10}B\) + \(_2^4 He\) → \(_7^{13}N\) + \(_0^1n\), Stable Radioactive Step II : \(_7^{13}N\) → \(_6^{13}C\) + \(_0^1e\) Radioactive (Spontaneous emission of position) Step-I can be considered as nuclear transmutation as it produces a new nuclide \(_7^{13}N\). However, The new nuclide is unstable (radioactive). Hence, Step-I involves artificial (induced) radioactivity. Thus, in artificial transmutation, A stable element is collided with high speed particles to form another radioactive element. |
