The aspects of measurement and presentation of radiation parameters of germicidal lamps, including radiant flux within the set spectral range, are under consideration. Radiant flux is currently used as their main parameter. There are the following methods of measurement of this parameter: indirect, by means of irradiance from the lamps, goniometric, and the integrating sphere method. The goal of the work was to compare the results of measurement of germicidal lamps using different methods and to analyse the practice of presentation of germicidal lamp parameters. TUV, HNS, LTC, DB, DKB and DKBU germicidal lamps and irradiators with different power capacity and peak radiation in the mercury line 253.7 nm were selected as the measurement objects and such parameters as radiant flux, germicidal flux, and radiant flux stabilisation time were selected as assessed parameters. The measurements were made and the values of radiant flux and germicidal flux, using the indirect and goniometric methods, were obtained. The graphs of radiant flux stabilisation of different lamps are presented. The analysis of the measurements demonstrated necessity of modification of the approaches to measurement and presentation of the germicidal lamp parameters.
