A Epilation
B:Longitudinal section of the hair
   and hair follicle
The hair and hair follicle
A: Age 18, female, exposed about 1.1 km from the hypocenter,
B: In the areas of epilation, the hair matrix including the dermal hair papilla that are the mother cells of the hair, and the connecting inner and outer root sheaths are severely affected.
C: Period of appearance of epilation and hemorrhage (deaths : total)
Period of appearance
Although some survivors suffered epilation as early as one week after the bombing, the majority of cases occurred in the third week thereafter. The epilation was often complicated by subcutaneous hemorrhage. (The hair returned to normal in most survivors after 12 to 14 weeks.)
D: Frequency of epilation and hemorrhage (by distance from hypocenter)
The frequency of epilation showed a close correlation with distance from the hypocenter, the number of cases increasing the closer the survivors were to the hypocenter at the time of the bombing.
