Objective: to estimate the risk of thyroid cancer incidence in the population of Ukraine in connection with its exposure to radioactive iodine fallout of Chornobyl origin and the use of pesticides in agricultural production in the country.

Object Of Study: Incidence rates of thyroid cancer in the population of Ukraine in 2001-2019, average regional radiation doses absorbed by the thyroid because of the Chornobyl accident, the volume of use of various groups of pesticides in the regions of Ukraine.

Research Methods: statistical, mathematical and cartographic.

Studies of the longterm oncological consequences after the Chornobyl accident show a significant impact of radiation exposure on the cancer incidence rate in affected population in Ukraine. This is supported by the increased radiation risk of leukaemia in liquidators, which exceeds national population rates, and its value is comparable to the data on hibakushi, who were subjected to Abombings. For the first time in the cleanup workers cohort the radiation dependence of chronic lymphoid leukaemia was established.

A large excess risk of thyroid cancer was observed among Belarusian/Russian/Baltic Chornobyl cleanup workers. A more recent study of Ukraine cleanup workers found more modest excess risks of thyroid cancer. Dose errors in this data are substantial, associated with model uncertainties and questionnaire response.

Article Synopsis
  • The study investigates the link between thyroid cancer risk in men and radiation exposure during adulthood, particularly among Ukrainian cleanup workers from the Chornobyl disaster.
  • In a case-control analysis involving 149 thyroid cancer cases and 458 controls, researchers estimated individual radiation doses, finding a mean exposure of 199 mGy, with some cases experiencing much higher doses.
  • Although the results suggest a possible association between radiation exposure and thyroid cancer risk, especially within a shorter time frame post-exposure, the findings show lower risk estimates compared to previous studies on adult radiation exposure after Chornobyl.
