somebody just might decide to try it once more for old times' sake.
In the Hiroshima attack (bomb yield approx. 15 kt) casualties (including fatalities) were seen from all three causes [burn, blast, and radiation effects]. Burns (including those caused by the ensuing fire storm) were the most prevalent serious injury (two thirds of those who died the first day were burned), and occurred at the greatest range. Blast and burn injuries were both found in 60-70% of all survivors. People close enough to suffer significant radiation illness were well inside the lethal effects radius for blast and flash burns, as a result only 30% of injured survivors showed radiation illness. Many of these people were sheltered from burns and blast and thus escaped their main effects. Even so, most victims with radiation illness also had blast injuries or burns as well.I'm not saying that more effective treatments for radiation sickness wouldn't be helpful. I'm just pointing out that CBS makes it sound like an equal number of people would be killed by radiation as by the primary blast effects, which is not the case.
With yields in the range of hundreds of kilotons or greater (typical for strategic warheads) immediate radiation injury becomes insignificant. Dangerous radiation levels only exist so close to the explosion that surviving the blast is impossible. On the other hand, fatal burns can be inflicted well beyond the range of substantial blast damage. A 20 megaton bomb can cause potentially fatal third degree burns at a range of 40 km, where the blast can do little more than break windows and cause superficial cuts.
