The Largest Risk of Iodine-131 on the Public
When the short-lived iodine splits, there is the formation of thyroid cells. When these cells collect or combine into one, they form iodide, which is as radioactive as the initial component material. The particles that result from these lines, form unstable radioiodine, which can cause delayed effects and chronic and acute effects. High doses of these concentrations lead to thyroiditis, because of acute effects. On the other hand, hypothyroidism, thyroid cancer, and thyroid nodules are because of the chronic effects of the sun’s UV radiation.
Considering the Soviet Union case, Chornobyl, and the Mayk cases, the iodine released caused great damage to cancer development. In Japan, iodine-131 has had exceeding safety limits in water purification plants in Tokyo. A similar occurrence has been an issue related to the February 2012 leaking of the crippled Fukushima nuclear power plant. This makes the place inhabitable for a long time, because of these radiations. For example, in the Chornobyl disaster, the ambient received about 10 % of emissions from the contained area. This made the affected area unfit for human settlement for a long time.
With reference to the current amount of radionuclide released to the ambient, the amount of I-131 radiation that is in the air is between 10 pBq to 700PBq. This is about 1% of the whole 40 percent of the 1760 PBq. This is proof that there is a lot of escape associated with the release of I-131 (Malley 18). Emissions that come from these leakages are vital to the environment, and therefore, they are causing devastating effects on the ambient. In April 2011, NISA and NSC record for the I-131 release was approximately 130 PBq and 150 PBq, which was about 30 grams of radioactive material. Soil samples from the regions around Fukushima, which include 2200 locations and 400 locations, showed contamination with the I-131, which is very dangerous. In such a case, total care is inevitable.
Considering the evaluations relating to the biokinetic behavior of radioiodine, the patients who had thyroid cancer, showed differences from other cases. The decrease in the rate of cancerous growth in the body showed that the problem is more defined and can be treated. In fact, in some clear cases, patients have shown improvements. Looking at treatment from day 1 to day 6, the average intake is an exponential curve of the concentration. From days 6 to 13, the changes are observable in the patient’s urine, which shows the liberation of the iodine. After 2 weeks, the exponential decrease curve for the concentration is at a half-life of 15 days. Exposure to the human body during one’s lifetime experience may lead to permanent cell damage to the skin. If one is lucky to survive the effects of the radiation, it is clear from the research that they will have mutations for life.
