@22 days until Hiroshima Summit: Radiation from atomic bomb

by Yuichi Ito, Staff Writer

Those who barely escaped the blast and heat rays of the atomic bomb suffered from the radiation that poured on the ground. As radiation is colorless, transparent, tasteless, and odorless, it is impossible to confirm whether or not a person has been exposed to radiation without a measuring instrument. Even those who had suffered only minor external injuries began to have acute sickness such as hair loss, nausea, fever, and generalized weakness immediately after the bombing.

Radiation also ravaged the bodies of citizens who had begun to rebuild their city in the burned ruins. Several years after the bombing, the incidence of delayed effects such as leukemia and cancer increased, and many people lost their lives. A blood disease called myelodysplastic syndrome was found to be related to the atomic bombing 60 years after the event. The effects of radiation are not temporary, but last throughout A-bomb survivors’ lives.
