Exposure to radioactive emissions has a cumulative effect on the body during a person's lifetime, which is another reason why it is important to avoid any unnecessary exposure to radiation. Health effects of shortterm exposure to radiation are shown in Table 2.
The kidneys are usually among the first organs to suffer damage in radiation toxicity, due primarily to the higher levels of acidity following radiation exposure and the cellular damage caused by radiation's concentration in a filtering organ like the kidneys.
The radioactive elements are mostly heavy (high atomic number), and within the deep high temperature inner regions of the Earth, where molten stone predominates, the heavier metallic elements, such as Uranium, would tend to sink to deeper levels – by virtue of the Archimedean Principle.
