                | Still seeking upper-air wind data Hiroshima City and HiSoF are still in search of meteorological observation data on/around the day of the Hiroshima A-bombing. Your help and collaboration would be enormously appreciated. For details about its research target, please refer to HiSoF news dated on May 29, 2012(see News page). |    
               
                |  |  | Purpose 
                  of this website |  The main purpose of this 
              website is to provide a database and the latest scientific findings 
              on local fallout and black rain from the A-bomb explosion at Hiroshima 
              on 6 August 1945, with a view to conducting an inter-laboratory 
              comparison of model simulations re-constructing local fallout and 
              black rain.

                Correcting and Replacing: Table 2 and Table 3 of the article "Radiation 
                survey activities in the early stages after the atomic bombing 
                in Hiroshima" by Tetsuji Imanaka in the HiSoF report "Revisit 
                the Hiroshima A-bomb with a Database : Latest Scientific View 
                on Local Fallout and Black Rain", July 2011, pp. 69-81, has 
                been corrected due to editing error. Those tables have been replaced 
                with the corrected version (see Database). 2011-07-15 
                launched a HiSoF report (see Publications page; for Japanese summary, 
                see Japanese page) and updated databases. 2011-02-08 
                Revised a table of contents of forthcoming book, added related 
                document, and renewed databases. 2011-01-07 
                Renewed the databases page and updated data on wind. 2010-11-25 
                The HiSoF website launched.

                  HiSoF in brief |  The Hiroshima Study Group 
              on Re-construction of Local Fallout from A-bomb in 1945 (HiSoF) 
              is a group of researchers including meteorologists, radiobiologists, 
              nuclear engineers, as well as experts in medicine, statistics and 
              other related fields. Hiroshima City invited researchers to perform 
              studies and re-examine the effects of local fallout and "black 
              rain" resulting from the explosion of the Hiroshima atomic 
              bomb.  More
