Long-term effects of nuclear radiation is generally in fact triggered by low levels of radiation that is not realized and are not anticipated until the years.
The general public, according to international regulations, it should not be exposed to radiation exceeds the average 1 mSv per year, meanwhile, workers in radiation areas specified must not receive more than 50mSv per year.
Radiation dose is very high, amounting to 100 thousand mSv will kill instantly. While 10 thousand mSv dose may also be killed, but after a few days or weeks, at doses of 3000-4000 mSv, it is likely to survive about 50 percent. These high doses can damage the intestines that causes vomiting and diarrhea or bone marrow damage that weakens the red blood cell production.
Lower doses, eg 2000 mSv rarely cause immediate danger to human life, but symptoms of radiation sickness can be felt as fatigue, vomiting and poor appetite for several days or weeks, sometimes accompanied by hair loss, but do not leave permanent injuries. While the dose of 1000 mSv would cause the symptoms temporarily, but there is no immediate risk to health.
