Abstract
The objective of the study was to estimate the value of the radiation dose absorbed in consequence of consumption of popular food products for individual age groups. Potatoes, corn and sugar beet were selected for the study. Edible parts of these plants were collected in experimental fields of the KWS Lochów Polska Sp. z o.o. seeding company in Kondratowice (Poland). On the basis of the obtained study results, it can be stated that in consequence of consumption of the selected food products, people may receive increased doses from both natural and artificial radioactive isotopes. The doses calculated for several age groups do not show any health hazards in consequence of consumption of the tested food. One of the determined radionuclides was 137Cs; however, its presence in the absorbed dose is lower than the doses from natural radioactive isotopes, in particular 40K.

IntroductionActivity concentration of natural radioactive isotopes in a given area is usually stable and low, it may vary in consequence of human activity
Natural background radiation originates mainly from uranium–radium, uranium–actinium, thorium series elements and radionuclide 40K, as well as from nuclear transformations of such gases as nitrogen, oxygen or argon under the influence of highly energetic cosmic radiation [1, 2].Paper presented during the 6th All Polish Conference on Radiochemistry and Nuclear Chemistry, Krakow (Poland), 21–24 April 2013.Activity concentration of natural radioactive isotopes in a given area is usually stable and low, it may vary in consequence of human activity

Summary
Activity concentration of natural radioactive isotopes in a given area is usually stable and low, it may vary in consequence of human activity. The increase of radioactive substances content in environment can be caused by mining industry, firing fossil fuels, use of phosphorus fertilizers and discharging mining waters to water reservoirs. Artificial isotopes may be found in natural environment when released in consequence of, for example, various breakdowns, careless operation of industrial facilities, nuclear weapon tests and nuclear accidents such as one that happened in Chernobyl in 1986. It is known that gastrointestinal tract is one of the main ways in which radioisotopes enter human organism [4]; it is necessary to monitor the content of radioactive substances in various elements of environment, in particular those used for food production
