Magnitude 9 earthquake in Japan(1) Easily lead to nuclear radiation types of cancer?

Backgrounder: METI nuclear safety and security of homes 14 announced, Fukushima Nuclear Power Station Unit 3 in the first 11:01 local time, hydrogen explosion occurred, the reactor where the building was damaged, but placing the reactor vessel was not damaged. Currently, the Japan Atomic Safety and Security Institute called the first nuclear power plant in Fukushima within a 20 km radius around the 600 residents of the house quickly to the refuge.

As has happened in human history, the atomic bomb, nuclear power plant leaks and other serious accidents, it is more and more insight into the vast and cold nuclear radiation lethality. How terrible nuclear radiation in the end? Nuclear leakage, explosion, nuclear radiation on the environment, human health will bring a long time, an immeasurable impact, and because of cancer caused by nuclear radiation is the most significant of a performance.
Carcinogenic radiation path -
Nuclear radiation are α, β, γ are three forms of radiation. α radiation can be blocked as long as a piece of paper, but a large inhalation hazard; β radiation burns after skin is exposed to significant; γ radiation and X-ray similar to the human body and can penetrate buildings, hazard distance.
How does nuclear radiation damage the human body from? Human body there are a lot of various molecules, nuclear radiation on the human body is first expressed in the destruction of these molecules, causing molecular properties change. However, the damage does not necessarily mean "cancer."
Only when the molecules can not repair damaged cells remained alive and the case of eventual uncontrolled cell replication, and finally grow into cancer cells, are considered because the occurrence of nuclear radiation causes cancer. However, it is undeniable that for a long time to accept a higher intensity of radiation will increase the possibility of human cancer.
Hot friends: Japan nuclear leak would cause a new round of cancer highlight?
Easily lead to nuclear radiation types of cancer?
According to the information retrieval found that the current radiation foreign pathogenic events occurring in patients with multiple manifestations of fatigue, dizziness, insomnia, skin redness, ulcers, bleeding, hair loss, leukemia, vomiting and diarrhea. Serious nuclear radiation will increase the cancer, distortion, the incidence of hereditary disease. In general, the body more energy radiation received, the more serious symptoms of radiation sickness, carcinogenic, teratogenic risk is also greater. Among them, those most vulnerable to nuclear radiation leukemia, lymphoma, skin cancer, thyroid cancer and other cancers.
Leukemia: high frequency radiation may be due to microwave radiation causes cells to change the DNA sequence or mutations, in particular the dramatic increase in white blood cells may lead to sudden imbalance of the immune system. After the atomic bombings in Japan, a sharp rise in leukemia patients that are powerful burst of nuclear radiation effects on human cells.
Lymphoma: Radioactive substances that can cause chromosome changes in lymphocytes a long period of radioactive material if the chronic injury state, cell survival is still difficult to repair themselves, the increased chance of cancer cells.
Skin cancer: in the nuclear radiation environment for people, human contact with the outside skin is the most widely used place. The face of volatile substances or diffuse radiation material, the skin will bear the brunt of exposure to risk. In addition, the yellow and white compared to white skin are more susceptible to radiation damage.
Thyroid cancer: If a large number of radioactive material released into the atmosphere, easy to mess with hair thyroid cancer, because these radioactive materials represent a large share of radioactive iodine, and iodine in human thyroid is the main gathering place, when the body is eating or inhalation of radioactive iodine, accumulation in the thyroid dose of radioactive iodine can damage the thyroid gland or surrounding tissue, a dose may induce thyroid cancer.
