Interpretation:
To fill in the blanks:
In addition to particles, many radioactive nuclei also produced high energy …....... rays when they decay.
Concept Introduction:
The unstable nuclei are called parent nuclei that forms the daughter nuclei either by combination or by decomposition of the nuclei. The radioactive decay is the conversion of the unstable nuclei to the stable nuclei with some other by product like alpha, beta and gamma particles. When they are formed by combination, the process is known as fusion and when they are formed by decomposition, the process is known as fission. The beta particles increase the
