- 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 .
