Kate Brown studied the health effects of the fallout from the Chernobyl disaster. The official reports almost always underestimated the morbidity and mortality rates, but records do still exist, under-examined, in the files of Russia and Belarus.

The IAEA won a contest with WHO as to which organization would keep the health records, but one must be skeptical about the numerical reports from the organization that does the research for IAEA.
