scenario.
Blast effects — the initial stage
Immediate post-attack period
The main causes of death and disablement in this state are thermal burns and the failure of structures resulting from the blast effect. Injury from the pressure wave is minimal in contrast because the human body can survive up to 2 bar (30 psi) while most buildings can withstand only a 0.8 bar (12 psi) blast. Therefore, the fate of humans is closely related to the survival of the buildings around them.
[Middleton, Hugh. "Medical Consequences of Radiation Following a Global Nuclear War." The Aftermath (1983): 50-56.]
Fate within certain peak overpressure
* over 0.8 bar (12 psi) - 98% dead, 2% injured
* 0.3 - 0.8 bar (5-12 psi) - 50% dead, 40% injured, 10% safe
* 0.14 - 0.3 bar (2-5 psi) - 5% dead, 45% injured, 50% safe

There is also the risk of internal radiation poisoning by ingestion of fallout particles, if one is in a fallout zone.
Radiation poisoning
Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to
ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of
radiation in a short period, though this also has occurred with long-term exposure to low-level radiation. Many of the symptoms of radiation poisoning occur as ionizing radiation interferes with cell division. There are numerous lethal radiation syndromes, including

Prodromal syndrome
The "prodromal syndrome" is not a diagnosis, but the technical term used by health professionals to describe a specific group of symptoms that may precede the onset of an illness. For example, a fever is "prodromal" to measles, which means that a fever may be a risk factor for developing this illness.

infections
The peak incidence of acute BM death corresponds to the 30-day nadir in blood cell numbers. The number of deaths then falls progressively until it reaches 0 at 60 days after irradiation. The amount of radiation greatly affects the probability of death. For example, over the range of 2 to 6 Gray the probability of death in untreated adults goes from about 1% to 99%, but these figures are for healthy adults. Therefore, results may differ, because of the thermal and mechanical injuries and infectious conditions.

Transgenerational genetic damage
Exposure to even relatively low doses of radiation generates genetic damage in the progeny of irradiated rodents. This damage can accumulate over several generations.
No statistically demonstrable increase of congenital malformations was found among the ''later conceived children born'' to
survivors of the Nuclear weapons at Hiroshima and Nagasaki.
The surviving women of Hiroshima and Nagasaki, that could conceive, who were exposed to substantial amounts of radiation, went on and had children with no higher incidence of abnormalities than the Japanese average.
