The short-term effect of the radioactive contamination
in Fukushima nuclear power disaster

A nuclear power disaster can result in terrible radioactive contamination. According to the report of Nuclear Safety and Security Institute, radioactive level in the central control room of Unit 1 reactor at the Fukushima Daiichi Station was 1000 times higher than its normal level after the earthquake. The communique reported that the amount of radiation around the gate of the nuclear power plant was increasing. It became 70 times higher than normal amount at 9 o’clock in 12th March. In March 2011,airborne fission products due to the Fukushima Nuclear Accident was detected in Seattle, WA, USA(1). Fallout radionuclides released in the Fukushima Nuclear Accident were detected in environmental samples at the city of Krasnoyarsk in April(2).

Radioactive contamination may pose major risks to both people and the environment. “It can enter the body through ingestion, inhalation, absorption, or injection.” After Fukushima nuclear power disaster, ingestion, inhalation, and absorption are main ways to enter body. People were affected through direct exposure, breathing, and eating contaminated foods or drinking contaminated water.

As we all know, radioactive contamination is very harmful to the health of humans. Generally speaking, low levels of radioactive contamination pose little risk. But medium and high levels of radioactive contamination can cause huge damage to humans’ health. Medium levels of radioactivity are likely to give rise to diarrhea, nausea, and vomiting and hair loss. High levels of it will hurt people’s central nervous system, even be life-threatening. If radioactive isotopes, such as iodine-131, are absorbed and accumulated in bones, people will come down with kinds of cancer. As for long-lived isotopes, such as cesium-137, even low level of radiation can be life-threatening when in long exposure to it(3). When people are directly exposed to radioactive...
