Question

Unit of the radioactivity is Rutherford. Its value is:

• A. $2.7\times {10}^{10}$ disintegrations/sec
• B. $3.7\times {10}^6$ disintegrations/sec
• C. $3.0\times {10}^{10}$ disintegrations/sec
• D. $1.0\times {10}^6$ disintegrations/sec

Answer 1

The correct option is D

$1.0\times {10}^6$ disintegrations/sec

The self-spontaneous disintegration that is the decay of unstable radioactive nuclei and the nucleus exhibiting this phenomenon is known as radioactive nuclei. Some examples of radioactive substances are Uranium, Radium, Thorium, Polonium, Neptunium etc.
