Why in gamma ray emission there is no change in A or Z ?

We know that in Alpha decay 2 protons and 2 neutrons are subtracted from the element. and in Beta decay there is change in atomic number by + or - 1. but why there is no any change in Gamma Decay in mass number A or atomic number.

i have asked this question to several forums but did not get a satisfactory reply..
