A multitude of things like immediate death, homelessness, loss of food sources and energy, radiation diseases or conditions, among other things
Some of the effects on the human body from a nuclear explosion are death (from thermal energy/blast effects or super lethal radiation exposure), infertility and blood disorders.
Most illnesses were cancer related because of the ionising radiation in the nuclear fall-out after the explosion.
nuclear explosion?

The only nuclear explosions in Japan were the two in WW2, on Hiroshima and Nagasaki.However I believe you meant the Japanese nuclear reactorexplosion, which was not a nuclear explosion it was either a steam explosion and/or a hydrogen/oxygen chemical explosion. That occurred at Fukushima.
When and what explosion? One of the nuclear test shots. If so which?Remember Chernobyl was not a nuclear explosion, it was a steam explosion and graphite fire.
The PTR level is intended to protect people and vehicles on a highway from the effects of an accidental explosion.

Many things. I'd need more details on exactly what effects you are interested in to say.
In a nuclear explosion, the intense heat and radiation can instantly vaporize the people closest to the blast site. The extreme temperatures and pressure generated by the explosion can cause flash vaporization of organic material within the blast radius.
