Explanation A 10 Ci β − emitter is situated at a distance 2 m from hand. Absorption of electrons in air is ignored. Write the expression of flux of electrons f = a 4 π r 2 (I) Here, f is number of electrons that strikes hand per unit area per sec, a is source activity and r is distance from source at which flux is to be determined. Conclusion: Substitute 10 Ci for a and 2 m for r in expression (I). f = ( 10 Ci ( 3

Radioactive decay

The emission of energy to produce ionizing radiation is known as radioactive decay. Alpha, beta particles, and gamma rays are examples of ionizing radiation that could be released. Radioactive decay happens in radionuclides, which are imbalanced atoms. T…

Artificial Radioactivity

The radioactivity can be simply referred to as particle emission from nuclei due to the nuclear instability. There are different types of radiation such as alpha, beta and gamma radiation. Along with these there are different types of decay as well.
