Intensity of the 662‐keV gamma ray from cesium‐137 was closely monitored in a variety of foods and beverages, including milk, flavored milk, fruit juices, infant foods, cooking oil, biscuits and fish. Nuclear facilities in the region, and the proximity of Oman to India and Pakistan (where nuclear material exists) played an important role in influencing our investigation. Relevant food items were obtained at appropriate intervals from January to December 2003 and 2004, and subjected to high‐resolution gamma‐ray measurement with a 28‐cm 2 high‐purity germanium detector. Each sample was prepared in a suitable Marinelli beaker and counted for 12 h. The recorded specific activities in milk, fruit juices and oil were generally < 1.0 Bq/L, and < 2.0 Bq/kg in solid foods such as fish and biscuits. In general, we found that the food quality in this respect was high.
