After the Chernobyl accident in 1986, the "liquidators" or clean-up workers were among those who received the highest radiation doses to the thyroid from external radiation. Some were also exposed to radioiodines through inhalation or ingestion. A collaborative case-control study nested within cohorts of Belarusian, Russian and Baltic liquidators was conducted to evaluate the radiation-induced risk of thyroid cancer.

In the framework of an epidemiological study of leukemia and other related blood diseases among Ukrainian cleanup workers, individual bone marrow doses have been estimated for 572 cases and controls. Because dose records were available for only about half of the study subjects, a time-and-motion method of dose reconstruction that would be applicable to all study subjects, whether dead or alive, was developed.

- A case-control study was conducted among Chernobyl liquidators to examine how low- to medium-dose radiation exposure affected the risk of developing hematological malignancies.
- Researchers analyzed data from 117 cases of cancer, including types like leukemia and non-Hodgkin lymphoma, and compared them to 481 matched controls.
- The study concluded that there was a significantly elevated relative risk of cancers at radiation doses of 200 mGy and above, with some estimates being consistent with previous studies of atomic bomb survivors, though there are concerns about potential biases affecting the results.
