The variation of galactic cosmic rays in the heliosphere in correlation with the solar activity presents a high scientific interest for several aspects. The possibility of studying the energy charge (& mass), spatial & temporal distribution of cosmic rays in the interstellar space, in the vicinity of the solar system, can provide a better understanding of astrophysical mechanism like, for instance, the acceleration of charged particles in a shocked plasma. Galactic cosmic rays in turn can be used as a unique tool for deeply understanding the characteristics & the dynamics of the heliosphere. So it is necessary & significant to investigate the role of various solar parameters in the variation of galactic cosmic rays. Solar radio flux is the energy emitted by the sun with a slowly varying intensity. The amount of this energy is high in the corona & it changes gradually day to day in response to the numbers of spot groups on the solar disk.
