Purpose: Studying individual burst characteristics recorded by the UTR-2 radio telescope UTR-2 during the Decameter pulsar/transient survey of northern sky, based on the analysis of 70 % of primary data.

Design/methodology/approach: Individual pulses, extracted from observation data by the RFI mitigation routines, are analyzed for the presence of cosmic radio source properties.

Findings: Analysis of parameter distributions such as the local time of individual pulse detection (due to RFI conditions) and the dispersion measure of recorded pulses suggests that most of the detected signals are generated by cosmic radio sources.

Conclusions: Processing of the remaining 30% of the data survey is essential, but, apparently, this will not significantly affect the distributions of individual characteristics of signals found in the course of the current survey. However, since the sources of transient signals are extremely difficult to be identified, to make an assertion of the cosmic origin of recorded signals, some additional tests are required to be made.

Key words: survey, transient, RFI, dispersion measure, decameter
