I will write about air counter again. But in this week I will write about Radioactivity too.

About radioactivity

Radioactivity is capability which a nucleus collapses and gives off radiation.
The substance is made of an atom. It was discovered by the Henry Becquerel in 1896, and was named by Marie Curie.

 

About radiation injury

It is called radioactive exposure that a human body is exposed to radiation. Or it is called contamination. The bad influence to the health by radiation is called radiation injury. For example, it is supposed that a half person will die from contamination of about 4 Gy.  After many years pass, the symptoms may be shown in leukemia or cancer.

 

Use of radioactivity

The character of radiation or a radioactive material is used and the substance with radioactivity is used in various fields. Although the radioactive material has been used for the time when the damage by radiation is not known well by noncommercial elegance, in the present age, it is no longer used.

 

About the offing earthquake of the Tohoku district Pacific Ocean

The offing earthquake of the Tohoku district Pacific Ocean is an earthquake which generated the offing of Pacific Ocean Sanriku in Japan as the focus at 14:46 on March 11, 2011. The Great East Japan Earthquake was caused and the damage serious all over East Japan from the northeast to Kanto was brought about. In Japan, it was the greatest scale in the history of observation. The dead are 15880 persons, missing person is 2694 persons, the injured are 6135 persons. And the nuclear power plant was destroyed by tsunami. So radiations leaked. The influence of radioactivity spread also to the sea. Fisheries were great blows for the prosperous northeast. The farmhouse also suffered da、mage.

 

The consequence of radiation having given Fukushima

1, Radioactive contamination, Japanese food, tap water, atmosphere, sea water, soil, etc.

2, Damage caused by rumors

3, Social influence and reaction scientific influence of other

4, Refuge and influence of the influence residents who give absorption and health of a human body

5, Influence on economy

etc.

 

Therefore, people were not able to eat at ease. So the corporation made air counter,

Now, damage caused by rumors are less.

 

When the earth quake was happened, the radiation detector sold by the foreign country.

So people couldn’t read and use. And it was too expensive because it was for corporations. Air counter was changed history of the radiation detector.
