an equal number of additional non-fatal cases, occurring over time both inside and outside the ex-Soviet Union". In contrast, even some 19 years later in September 2005, an official UN IAEA report claimed 4,000 deaths as the final estimated toll from Chernobyl. In their 2006 book Alexey V. Yablokov and other Russian and East European researchers estimated that Chernobyl caused a million deaths through 2004, nearly 170,000 of them in North America. The book's English translation was published by the New York Academy of Sciences in 2009. The book cites "5,000 mainly Slavic-language scientific papers the IAEA overlooked", notwithstanding the fact that 13 of the authors of the Chernobyl Forum were from Ukraine, Russia or Belarus. M. I. Balonov criticized the methodology of the book. M. I. Balonov criticized the methodology of the book's estimation of Chernobyl's excess deaths and radiation-induced health effects and claimed the numbers were exaggerations which "could lead quite unnecessarily to a panic reaction". Rosalie Bertell has asserted the above estimates of Gofman (1986) and Yablokov (2006) are too conservative.
