1. Nuclear radiation effects on human
health
● Radiation is not always dangerous
● There are two kinds of radiation
● What is ionizing radiation
● Dangerousness of ionizing radiation
● The difference between non-ionizing radiations
and ionizing radiations
● Dangerousness of nuclear bomb
● The damage of Hiroshima where the nuclear
bomb exploded

2. Radiation is not always dangerous
● All radiation is not always harmful.
● Of course, there is very dangerous radiation.
● But we use it as radio, cellphone waves in the
life. And we can cook by using it.
●This wave is classified into non-ionizing radiation
and believed not to cause the cancer.

3. There are two kinds of radiation
● There are ionizing
radiation and non-
ionizing radiation.
● The latter is not
dangerous through
referring to the previous
slide.
● But the former would
be dangerous because
it can break chemical
bonds and cause the
cancer.

4. What is ionizing radiation
● The difference between ionizing radiation and
non-ionizing radiation is whether harmful or not.
● Ionizing radiation includes X-rays, gamma-
rays,alpha-rays and beta-rays.
● But ionizing radiation is not harmful in the
particular case. The case is related to how long
you are exposed.
● The First symptom of this wave is used for
remedy of the cancer . This is a ionizing
radiation's merit.

5. Dangerousness of the ionizing
radiation
● The first symptom is to
cause nausea, fatigue
and vomiting.
● The second is to cause
hair loss and diarrhea.
● The third is to cause
worse diarrhea and
dehydration.
● The forth is to cause
consciousness loss and
death.

6. The difference between non-
ionizing radiations and ionizing
radiations
This is pictures that explain radiation's merit and
demerit

7. Dangerousness of nuclear bomb
● When a nuclear bomb
explode, it produces X-
rays and gamma-rays.
● Also, it makes the cloud
of radiative ash. The
rain or dust from this
cloud is known as
fallout.
● It can accumulate on
foods. So we receive
the radiation when we
don't know.

8. The damage of Hiroshima where the
nuclear bomb exploded
● The nuclear bomb was
fallen in 1945.
● About 166,000 people
were killed by the blast
and the radiation which
were X-rays and gamma-
rays.
● The radiation on foods
can cause the cancer. It
made from this bomb
killed 100,000 people that
isn't exact number .
