The results were compared to the data from the period 1985-98. Since the Chernobyl accident gradual decreaase of contamination level has been observed. The gamma dose rate and the contamination of air, fallout, tap and surface water were at the level of 1985. The only contamination enhanced in relation pre-Chernobyl period was the content of cesium isotopes in soil and as a consequence food contamination was higher particularly milk and meat. At present, the source of additional dose is ingestion of artificial isotopes with food as a result of food contamination. No significant regional differences in the distribution of the level of cesium in food over the territory of Poland has been registered. Milk can be assumed as a main contributor of cesium to the diet, its share is about 34 percent of annual intake of cesium. The average effective dose, resulting from the contaminated food consumption, was estimated to be the level of 13 microSv per capita of the Polish population in 1999
