The Affect of nuclear radiation

Disasters in Japan sparked fears of a nuclear reactor meltdowns as happened at Chernobyl in 1986. The Impact of radiation is vary, some can be felt immediately and some are emerging in the long term.

The worst nuclear reactor meltdowns in history occurred in Chernobyl, Ukraine in April 1986. Besides causes the evacuation of thousands of residents near the scene, the effects are still felt by the victims until many years later. They are such as cancer, cardiovascular disorders and even death.

Naturally, the human body has mechanisms to protect themselves from cell damage from radiation and other harmful chemicals things. However, as quoted by FoxNews, radiation at a certain level can not be tolerated by the body with that mechanisms.

The FoxNews health editor, Dr Manny Alvarez said there are 3 factors that affect the impact of nuclear radiation. All those include the total nuclear radiation, how close the radiation source and the last is how long the victim affected by radiation.

These three factors will determine what the impact that will be felt by victims. High radiation can directly causes a direct impact that can be known quickly, while unfelt radiation can cause the long-term effects that are usually even more dangerous.

Momentary or short-term impact due to high radiation of nuclear reactors are as follows:

  • Nausea vomiting
  • Diarrhea
  • Headache
  • Fever

Meanwhile, the emerging impact of exposure to the nuclear radiation after several days are as follows:

  • Dizzy, dizzy eye
  • Disorientation or confusion of determining direction
  • Weak, tired and looked listless
  • Hair loss and baldness
  • Blood Vomiting or bowel bleeding
  • Low blood pressure
  • Hard to heal wounds

The impact of chronic long-term of nuclear radiation would generally be triggered by low levels of radiation that is not realized and are not anticipated until the years.

Some of the lethal effects of nuclear radiation exposure due to long-term are as follows :

  • Cancer
  • Premature aging
  • Nervous and reproductive system disorders and
  • Nervous and reproductive system disorders and
  • Genetic Mutation

How to recognize the sign of tsunami

Tsunami often takes so many victims.., there should be an early warning to the public. Although technology can already predict some disasters but it is very important to recognize the signs before the tsunami disaster particularly, in order to immediately secure our self.

The tsunami is a series of waves caused by landslides or large earthquakes that occur both on land and at sea. The tsunami waves can occur 5 minutes to 1 hour after a landslide or earthquake.

Here are some early signs of the arrival of the tsunami disaster, as reported by eHow and :

If you live near the coast, you should be careful when an earthquake occur. Tsunami usually come after the earthquakes that occur below or near the sea. It’s not only earthquakes that occur in your area, but also around the world. The earthquake of thousands kilometers away can potentially causes the deadly tsunami in your area.

Listen to the roar
There are many tsunami victims have said that the arrival of the tsunami waves will be preceded by a loud voice roar that similar to a freight train

Note the decrease of sea water
If the decline of sea water is rapid and it is not in the time of low tide, so you must immediately looking for refuge high. Before the tsunami, the sea will recede quickly first and then come back with enormous power

Always alert in the first wave
The first tsunami wave is not always the most dangerous, so stay closer to the shoreline until the circumstances are completely safe. Do not assume that a small tsunami at one place will be small also in other areas. The size of tsunami waves varies and is not the same at all locations. The tsunami waves also can travel through the rivers that connect to the sea.

Besides these signs, nature can also give a sign before the disaster, such as unusual wind movement, air pressure or extreme weather and the change of animal behavior. Scientists theorize that animals are able to capture the vibrations or air pressure changes around them that can not be done by human. “I do not think that this is the sixth sense, at least we can measure nothing at this time,” as said by Diana Reiss, Ph.D., director of marine mammal research at the Wildlife Conservation Society, based at the Bronx Zoo in New York City, such as reported by FoxNews.

Some bats, which are nocturnal and usually sleep during the day, became very active a half hours before the tsunami came. In Sri Lanka and Thailand there is a story about the elephants that ran to the hills one hour prior to the 2004 tsunami that destroyed villages and killed up to 150,000 people in both countries.
