Answer to Question #9122 Submitted to "Ask the Experts"Category: Radiation Effects — Hiroshima and Nagasaki The following question was answered by an expert in the appropriate field: Q
What are the long-term consequences of the bombing of Hiroshima?
A
There
were many long-term consequences of the 1945 bombings of Hiroshima and Nagasaki. I will focus my response on those related to radiation and health
physics. First, it is important to recognize that thousands of Japanese
citizens perished in the explosion and the fires that immediately followed. The
long-term effects of radiation exposure among the survivors have been
extensively studied in what has come to be known as the Life Span Study. The main effect observed has been an excess of
approximately 400 cases of cancer among the approximately 100,000 survivors.
That means that about 400 more cancers have been observed in this population
than would have been expected from a similar, but unexposed population. This
excess has been observed among the survivors who received the highest radiation
doses (generally, those who were closest to the detonation site).
I hope you find this information useful. Regards, Brant Ulsh, PhD, CHP
