Radiological tests were carried out on steel girders of composite bridges located on the Central Trunk Railway Line (CMK) in the years 1985-1986 according to the technical program of Transportation Ministry MK-133-06-02-04. The paper presented the test results obtained on seven composite steel-concrete railway structures. The aim of the tests was the identification of welding imperfections (WI) in butt splices of main girders and influence on their condition after the ten-year service. The test results may be useful for the technical assessment of the bridges associated with the adjustment to speed of 300 km/h. The tests confirmed the good quality of welds in bridge structures under consideration.
