There are different biological effects that occur when human bodies are exposed to radiation from a nuclear blast. When we are exposed to the radiation, the body will absorb some of the energy. There are different types of radiation, which are not all equally dangerous. Biological effects from radiation are divided into the two categories of acute radiation illness and long term effects.

Some symptoms are nausea, vomiting, and diarrhea. Infections that may eventually have fatal results will develop over a length of time as the immunity defense is put out of action. At strong doses of radiation, death may occur within forty-eight hours, because of destruction to the nervous system.

Long time effects can be caused by minor doses. The main...
