The properties of powerful (flux >10-19 W m-2 Hz-1) type III bursts observed in July - August 2002 by the radio telescope UTR-2 at frequencies 10 - 30 MHz are analyzed. Most bursts have been registered when the active regions associated to these bursts were located near the central meridian or at 40° - 60° to the East or West from it. All powerful type III bursts drift from high to low frequencies with frequency drift rates 1 - 2.5 MHz s-1. It is important to emphasize that according to our observations the drift rate is linearly increasing with frequency. The duration of the bursts changes mainly from 6 s at frequency 30 MHz up to 12 s at 10 MHz. The instantaneous frequency bandwidth does not depend on the day of observations, i.e. on the disk location of the source active region, and is increasing with frequency. The results of observational properties are discussed in the frame of the standard plasma model of type III bursts radio emission.
