The signs of people exposed to radiation does not always appear later, there also could be identified on the spot, especially if high enough levels of radiation. Symptoms range from dry skin, nausea, vomiting and killed instantly.

Various symptoms appear shortly after exposure to radiation is called Acute Radiation Syndrome (ARS). The higher levels of radiation, its effects appear sooner or felt by the victim and also the greater the chances of causing death.

Such syndrome experienced by many victims of the bombing of Hiroshima and Nagasaki in 1945 and the Chernobyl tragedy in 1986. Because the levels of radiation are released in these events is very high that trigger symptoms that are acute.

The Chernobyl tragedy in 1986, at least 134 workers and firefighters are exposed to radiation for 80-1600 brake. Of these 2 people were killed on the same day, while 23 people were killed in the next 3 months, all related to the radiation received.

While the symptoms may be observed based on the levels of radiation are as follows.

50-10 rem
Cell damage, changes in chemical composition of blood and increased risk of cancer. On the radiation exposure of this magnitude there are symptoms that can rarely be observed because the effect will appear in the long run, between 5-20 years later.

50-55 rem
Various minor complaints such as stomach nausea, headache and tiredness is a symptom that is often felt at this level. Sometimes accompanied dequamation or peeling skin, dry lips and sore eyes.

70-75 rem
At this level, radiation may cause vomiting. For a more sensitive, the hair will begin to experience hair loss.

350-400 brake
Can trigger death in the next 2 months.

More than 500 brake
Can trigger death in the next 30 days.

* Note: 1 brake equivalent to 10,000 microsieverts (mcSv)

Although not always led to symptoms that are easily recognized, the impact of radiation is still alarming. It's when it sparked a low radiation damage in tingkal cell, chronic impact is no less serious because it can cause cancer and genetic mutations.

Especially since the source of radiation not only nuclear reactor, but also from objects that are often encountered daily starting. Although low, the radiation emitted if not controlled it can lead to long-term impact.

The following are the sources of radiation that can be found in everyday environments, and their estimated level radasi emitted in a year.

3500-4000 mcSv
Radiation at this level can be encountered when living in the highlands, or perform a scan with the most high-powered X-rays.

1500-2000 mcSv
Radiation source at home, especially coming from the wall and foundation cracks. Rocks and other material originating within the earth containing Radium (Ra) which can escape into the radioactive gas radon (Rn) if broken or have cracks.

Less than 1,500 mcSv
Various devices in a hospital radiology emit less radiation than 1,500 mSv.
