The relationship  the intensity of the proton flux I_p of solar cosmic rays (SCR) with the parameters of continual radio bursts of the IV type, with the speed of coronal mass ejections (CME) of V_CME, as well as with the parameters of slowly drifting radio bursts of type II is investigated. Comparative analysis showed that for the vast majority of proton events a strong correlation of the intensity of the proton flux I_p with the integral flux ∫F_μdt of microwave bursts and the CME velocity V_CME is observed, where the correlation coefficient r between the investigated parameters is 0.80 and 0.72, respectively. Earlier, the author reported on a strong connection between the  integral flux ∫F_μdt  of the microwave bursts  and the CME velocity V_CME, where the correlation coefficient r between the investigated quantities is about 0.80. The strong connection between the intensity of the proton flux I_p and the integral flux ∫F_μdt of microwave bursts and the speed of the CME, as well as the strong connection between the  integral flux ∫F_μdt of the microwave bursts and the CME velocity V_CME, attests about the common origin of SCRs and CMEs during proton flares. In this paper it is also shown that there is a strong relationship between the intensity of the proton flux I_p and the parameter of type II burst V_II, which characterizes the shock front displacement velocity. Moreover, the relationship between the intensity of the proton flux I_p and the parameter V_II depends to a large extent on the frequency f₂ of the maximum of the type II radio burst on the second harmonic at a given time t and on the energy of the protons E_p. The maximum correlation between the proton flux I_p and parameter V_II is observed for protons with an energy E_p>30 MeV and for the upper frequency f₂ in the range 25-60 MHz.
