Hi everyone, now I want to write something about the Japan radioactivity, specifically the Fukushima disaster. The radiation leak in Japan is a topic very serious. The radioactive leak occurred in Fukushima, a northern city, near to the ocean. This disaster produced that many people had to leave their homes and abandon their pets. Neighboring countries are also concerned about contamination through the wind and rain

.

Is important to say that the nuclear plants are near to the sea or some lake because they need to cooling her system, and this way with cool water they controlled the radiation. Also I want to say that the sea water is salt an causes corrosive damaged in metal, is very probable that the nuclear plant in Fukushima had a special system to removed the salt.

I know that the leak is due to a lack in the cooling system, because this system was damaged by the sea water. The earthquake, 8,9 on the Richter scale, caused that the sea water damaged the emergency cooling system that was electric. This earthquake caused a tsunami with waves of ten meters of height.

The comparison between Fukushima and Chernobil is interesant because the radioactivity in Chernobyl was caused by the explosion of an reactor and in Fukushima was caused by a lack in the electric emergency system and the pollution radioactivity was gradually expanding through the cracks produced by the earthquake.

Bye
