Nuclear Radiation Effects in Japan

 Source: Wikipedia - Radiation effects from the Fukushima Daiichi nuclear disaster

The radiation effects from the Fukushima Daiichi nuclear disaster was a release of radioactive isotopes from the Fukushima Daiichi Nuclear Power Plant. Radioactive isotopes were released from reactor containment vessels as a result of venting to reduce gaseous pressure, and the discharge of coolant water into the sea. Nuclear plant could cause 130 deaths from cancer globally and 199 cancer cases in total, most of which are estimated to occur in Japan. Radiation exposure to workers at the plant was projected to result in 2 to 12 deaths and there are 167 Fukushima plant workers received radiation doses that slightly elevate their risk of developing cancer.Trace quantities of radioactive particles from the incident, including iodine-131 and caesium-134/137, have since been detected around the world.The World Health Organization (WHO) released a report that estimates an increase in risk for specific cancers for certain subsets of the population and it was predicted that for populations living in the most affected areas there is a 70% higher risk of developing thyroid cancer for girls exposed as infants, a 7% higher risk of leukemia in males exposed as infants, a 6% higher risk of breast cancer in females exposed as infants and a 4% higher risk, overall, of developing solid cancers for females.

Thirty workers conducting operations at the plant had exposure levels greater than 100 mSv It is believed that the health effects of the radioactivity release are primarily psychological rather than physical effects. Even in the most severely affected areas, radiation doses never reached more than a quarter of the radiation dose linked to an increase in cancer risk. (25 mSv whereas 100 mSv has been linked to an increase in cancer rates among victims at Hiroshima and Nagasaki) However, people who have been evacuated have suffered from depression and other mental health effects.

The United Nations Scientific Committee on the Effects of Atomic Radiation is expected to release a final report on the effects of radiation exposure from the accident by the end of 2013.

 Personal Reflection
The owner of this business should have prepared better, especially this case related to people's health. They should have have double-or-maybe-triple or more protection to prevent this disaster to happen. I suppose they should think about the worst effect and make a way out to prevent those effect so it would not happen in the future. If it did happen, they should take care of the problems they have made immediately. The main point is to prevent rather than conquer, because it is harder to take control than prevent it to happen I guess.
