The natural sources of radiation represent the cause of the minimal contamination of the environment, including air, water, soil and generate the level of radioactivity detected in vegetal or animal food, under normal conditions. Of artificial radio nuclides which pollute the environment and food, the object of this study is 134 Caesium and 137 Caesium (134 Cs and 137 Cs), both because of their particularity to own a chemical structure similar to potassium (K+), the prevalence in food of animal origin and total and rapid solubility in the body, and because of the usual measurements made in our country in order to detect the levels of radioactive contamination of food, aiming mainly the two mentioned isotopes of Caesium (134 Caesium and 137 Caesium). Given the fact that the eggs and egg products are not included in Romania in a strategic plan for monitoring the level of radioactive pollution, this study in dynamics, aims at recording the level of the two isotopes of Caesium, in the mentioned food products and at verifying if the detected values, are according to the rules laid down by the national and international norms. Thus, the comparative evaluation of the radioactive pollution in a year was aimed, at eggs collected from hens grown in particular, extensive, traditional system, compared to the eggs collected in the same period of time, in trade, from authorised units, from hens exploited in intensive system.
