The V/Vmax test is applied to gamma-ray bursts of duration longer than 1 sec recorded by the Konus experiment, to examine quantitatively the uniformity of the burst source population. A sample of 123 bursts detected on Venera 11 and Venera 12, gives mean V/Vmax = 0.45 + or - 0.03, consistent with 0.5, the value expected for a uniform distribution in space of the parent population of burst sources. It is argued that experimenters give careful attention to the detection limit for each recorded gamma-ray burst, and that quantitative data for burst properties and detection limits should be published. 28 refs.
