CESIUM 137 (I think we can start attacking there)
Health Effects "Humans may be exposed to cesium by breathing or by ingesting food and beverages. In air cesium levels are generally low but radioactive cesium has been detected in some surface water levels in many types of comidas.La amount of cesium in food and water depends on the emission of radioactive cesium nuclear power plants , mostly through accidents. When contact with radioactive cesium, which is highly unlikely, the person can experience cell damage due to radiation emitted by cesium particles. This can result in effects such as nausea, vomiting, diarrhea and bleeding. If the exposure is long people can even lose consciousness, enter coma or even death. How serious are the effects depends on the strength of any person, the exposure time and concentration to which it is exposed. "1 cesium is difficult to find in high doses as a result of a steel mill, is our weak point in this appearance but if so the health consequences can be disastrous ....
Environmental effects of cesium
Cesium is found in nature mainly because of the erosion and weathering of rocks and minerals. It is also released into the air, water and soil through mining and manufacturing of minerals. Radioactive isotopes of cesium may be decreased only in their concentration through radioactive decay. Non-radioactive cesium can also be destroyed when it enters the environment or react with other compounds in very específicas.Tanto molecules radiocaesium act chemically as stable as the bodies of humans and animales.El cesium in air can travel long distances before plunging into the earth. Most cesium compounds are very soluble in water. In soils, on the other hand, cesium can not be removed by the groundwater, there remains in the upper soil layers and is strongly attached to the particles of the same, and as a result is not available for uptake by roots plants. Radioactive cesium has the opportunity to enter the plants by falling on the leaves. Animals that are exposed to very high doses of cesium show changes in behavior, such as increased or decreased activity. 2 1.2.
