How long did it take for hiroshima to be habitable?

Answer 1

Leukemia, Lymphoma and Multiple Myeloma, Nervous sytem tumors and their response relation were obeserved for all solid nodules, adenoma, nodules without histological diagnosis, autoimmune hipothyroidism,stomach tumors and breast diseases. The population has a long follow-up (50 years) and includes both sexes and all ages of exposure, allowing a direct comparation of risks by these factors. the population has a long follow-up (50 years) and includes both sexes and all ages of exposure, allowing a direct comparation of risks by these factors.Because of the use of Japanese family rgistration system, mortality data are virtually complete for survivors who remained in Japan.

The serult in the coral reefs in the Binini Island who were demolished by nuclear blast came alive again after 50 years.

Answer 2

In terms of radioactivity, the city was considered immediately habitable as the levels of residual radioactivity was well below any that might produce acute illness.

In terms of housing and infrastructure, the city was effectively completely demolished. It took about two years with large amounts of financial aid from the occupation government to build a fully habitable city, almost from scratch.

Note: although the levels of residual radioactivity were well below any that might produce acute illness, chronic illness has resulted from two different causes.

1. survivors of the bombing itself had received much higher doses at the time of detonation and all had acute radiation illness. this population has had many and often multiple chronic illnesses attributable to radiation
2. those born after the bombing and new residents that have moved in receive continuing very low levels of radioactivity (the residual radioactivity decreases over time). the exact long term effects of this are still uncertain, but higher than normal rates of many illnesses of often uncertain cause have been seen in this population.
