Natural and artificial radioactivity concentrations of the white cheese, whey powder, milk powder, labaneh, kaskhaval cheese and milk were determined via gamma spectrometric method. For this purpose, p-type 110% relative efficiency coaxial HPGe detector was used. Average 40K radioactivity concentrations of the white cheese, whey powder, milk powder, labaneh, kaskhaval cheese and milk were found to be 63.1 ± 7.1, 392.6 ± 40.2, 482.1 ±38.6, 152.0 ±12.1, 48.7 ± 5.8 and 52.2 ± 4.2 Bq/kg respectively. 137Cs radioactivity concentrations were found to be below MDA. Except the milk powder 232Th  radioactivity concentrations were found to be below MDA. 232Th  radioactivity concentrations of the milk powder samples were found to be ranged  from 3.2 ± 0.3 - 9.8 ± 0.8 Bq/kg. 226Ra  radioactivity concentrations were ranged from 5.9 ± 0.5 - 8.3 ± 0.7 Bq/kg for whey powder, 5.1 ± 0.5 – 9.8 ± 0.8  Bq/kg for milk, 4.6 ± 0.5 -  9.9 ± 1.9 Bq/kg for white cheese, 3.5 ± 0.3 - 16.0 ± 1.5 Bq/kg for milk powder,  4.2 ± 0.3 - 11.1 ± 1.0 Bq/kg for labaneh.
