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.
I wrote about ST corporations for 10 weeks.
I just like ST corporation. I’m not the president’s daughter. And I’m not
