Abstract Activity concentration of natural radionuclides and 137Cs were estimated in 28 honeys purchased from large supermarket chains in Italy. Uranium, polonium and thorium were measured by alpha spectrometry, 40 K and 137Cs by gamma spectrometry and 226Ra by liquid scintillation. The concentrations were 50.6 ± 46.3, 0.023 ± 0.010, 0.019 ± 0.017, 0.27 ± 0.40 Bqkg−1 for 40 K, 238U, 234U and 210Po respectively. 235U, 228Th, 232Th were consistently
