2. Beginning of the presentation
● Recently, the Fukushima nuclear plants are
broken by the Tohoku earthquake.
● We expose people working and living around the
Fukushima nuclear plants.
● But the nuclear accidents had happened on the
world, and it had happened in Japan.
● We should learn to have to do something for the
nuclear plants from the nuclear accidents
happened now.
● Let's know about the nuclear accidents.
3. Before to know the nucler accidents
● We should know effects of radiation on human
health.
● The radiation is measured as rem.
● When you are exposed to
○ near 100 rems, you have
■ nausea, vomiting, headache, some loss of
white blood cell
○ near 300 rems, you lose your hair.
○ 450 rems, you can be died.
○ 800 rems, it is certain that you are died.
4. Two atomic bombs dropped in
Hiroshima and Nagasaki (1)
● The atomic bomb is a very cruel weapon.
● Many people were died in Hiroshima and
Nagasaki by the atomic bombs.
● But there are more people killed by the
radiation than people killed by the actual
explosion .
● For example, a case of 14-old boy exposed to
radiation.
○ Two days later, the first signs come out on
him.
○ Nine days later, his hair began to fall out, and
his white blood cells decreased.
5. Two atomic bombs dropped is
Hiroshima and Nagasaki (2)
○ On the seventeenth day he began to blood from his
nose.
○ On the twenty-first day he died.
● At that time,
○ There are only the few surviving doctors, and they
hadn't examined and treated radiation patients.
○ So, they didn't know the cause of the symptoms
and the method of treatment for radiation.
● As a result, Many people died by the radiation
● If the doctors knew the cause and the method of
treatment , there may be some people living now.
6. The nuclear plants accident in
Chernobyl (1)
● The nuclear plants accident in Chernobyl is more
serious accident.
● Because of happening the nuclear
accident, though people used the Chernobyl to
generate 1000 megawatt electricity, they didn't
have any question plants, ignored, and were
careless about the nuclear.
● So they were late handling the nuclear plants
accidents.
7. The nuclear plants accident in
Chernobyl (2)
● in the time of the nuclear accident, the nuclear
plants spread the radiation like the nuclear bomb.
● The explosion having gusses and radiation had
happened because the people didn't think about
the Chernobyl nuclear plants.
● The radiation is in around the Chernobyl nuclear
plants now.
● They should had thought about the nuclear plants
before the nuclear accidents.
8. Things learning for the nuclear
accidents
● We should needs to know the nuclear plants
and the exposure of radiation, and
prepare countermeasure against the nuclear
accidents.
● And we should prevent the nuclear accidents.
● Because, the radiation remain for a long time.
● Finally,
○ The nuclear accidents must not be happenned.
○ For that reason, we should know about the
nuclear and make measures against it.
