Introduction Radiation is a very usefultechnology for our life. However, it has some dangerous side.
There are two types of radiation. 1. Non-ionizing radiation. This radiation isused in our life. For example, infrared, radio waves, cellphone and micro waves. 2. Ionizing radiation. This radiation causecancer. For example, X-rays, gamma rays, alpha particles and beta particles.
What are symptoms caused by radiation.First, if we are exposed 500,000microsieverts, the radiation cause nausea, fatigue and vomiting.Second, if we are exposed 750,000 microsieverts, the radiation cause hair loss and diarrhea.
What are symptoms caused by radiation. Third, if we are exposed 1 million microsievert, the radiation cause sserious diarrhea and dehydration happens because intestinal lining is destroyed. Finally, if we are exposed 4 millionmicrosieverts, the radiation cause lose own consciousness and death.
Dangers about a nuclear bomb Nuclear bomb burst itself andirradiate X-rays and gamma rays. In Hiroshima, 166,000 Japanese people were killed by a nuclear bomb in first four months.
Dangers about nuclear plantsFukushima nuclear plants are notemitting X-rays and gamma-rays.But radiocesium and radioiodine has probability to increase cancers.
ConclusionRadiation bring us to some seriouseffect. We should think that how to use it for our life safety.
