analysis: The text appears to be discussing the effects of the Chernobyl nuclear accident on the environment, agriculture, and human health. It mentions the exposure to deposited radionuclides, the evaluation of doses, and the estimation of health risks. The text also highlights the role of specialized agencies such as the Food and Agriculture Organization (FAO) and the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) in assessing the impact of the accident.
