Beyaz peynir, peynir altı suyu tozu, süt tozu, labne, kaşar peyniri ve sütün
doğal ve yapay radyoaktivite konsantrasyonları gama
spektrometrik metot ile belirlendi. Bu amaçla, p-tipi %110 rölatif verimli eş
eksenli HPGe dedektör kullanıldı. Beyaz peynir, peynir altı suyu tozu, süt
tozu, labne, kaşar peyniri ve sütün  ⁴⁰K  ortalama radyoaktivite konsantrasyonları sırasıyla
63.1 ± 7.1, 392.6 ± 40.2, 482.1 ±38.6, 152.0 ±12.1, 48.7 ± 5.8 ve 52.2 ±
4.2 Bq/kg dir. ¹³⁷Cs
radyoaktivite konsantrasyonları MDA altında bulunmuştur. Süt tozu dışında ²³²Th
radyoaktivite konsantrasyonları MDA
altında bulunmuştur. Süt tozu ²³²Th radyoaktivite konsantrasyonu 3.2 ± 0.3 - 9.8 ± 0.8 Bq/kg
aralığında bulunmuştur. ²²⁶Ra 
radyoaktivite konsantrasyonları peynir
altı suyu tozu için 5.9 ± 0.5 - 8.3 ± 0.7 Bq/kg, süt için 5.1 ± 0.5 – 9.8 ±
0.8  Bq/kg, beyaz peynir için 4.6 ± 0.5 -
9.9 ± 1.9 Bq/kg, süttozu için 3.5 ± 0.3 - 16.0 ± 1.5 Bq/kg,  labne için 4.2 ± 0.3 - 11.1 ± 1.0 Bq/kg
aralığında bulunmuştur.

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.
