We have calculated accurate integral radio luminosities L for 232 pulsars (Malov et al., 1994) using new average spectra of these objects. Histogram of L-distribution is characterized by the mean value < log L >= 28.45 and by the mean-square-root deviation S = 1.0. We have analysed also data for short-periodic pulsars (P < 0.1 s) and long-periodic ones (P > 1 s) separately.The main goal of such separation was to test the hypothesis on two types of pulsars (Malov, 1987): i) for the first group of objects radiation is emitted from the neighbourhood of the light cylinder (r = rLC = cP/2π, P is the pulsar period), ii) for the second one emission is generated at distances r ≪ rLC. In the second case the main mechanism of radiation is curvature radiation. For the first group of pulsars the radiation is connected with the cyclotron mechanism. The difference between two basic mechanisms and the locations of the emission generation regions must cause some differences in the observable features for these two classes of pulsars.
