I meant it in the sense that at least half the victims (70k immediately + some tens of thousands within a day) died before radiation poisoning or other radiation-induced effects, such as cancer, had time to set in. Considering how dire the situation was there in the absence of... well,
anything that could help, most of the injured people who died within the first few days most likely wouldn't have survive had there been no radiation poisoning, as they still had to deal with blood loss, sepsis, and whatnot. Here's an estimate from the US's
survey on the effects of bombings:
A plausible estimate of the importance of the various causes of death would range as follows:
Flash burns, 20 to 30 percent.
Other injuries, 50 to 60 percent.
Radiation sickness, 15 to 20 percent.
It should be noted that, with residual radiation from the bombings and the current leakage scenario, people have (had) a choice whether to move further away from the source to avoid abnormal continuous exposure. I know I would.
