Cosmic radiation consists of very energetic particles, mostly high-energy protons, which bombard the Earth from outer space. They comprise about one-tenth of natural background exposure at sea level, and more at high altitudes.
The health effects of exposure both to radiation and to chemical cancer-inducing agents or toxins must be considered in relation to time. There is cause for concern not only about the effects on people presently living, but also about the cumulative effects of actions today over many generations.

The FDA has approved two different forms of KI (potassium iodide), tablets and liquid, that people can take by mouth after a radiation emergency involving radioactive iodine.
UNEP notes: &ldquo While the release of radon in underground uranium mines makes a substantial contribution to occupational exposure on the part of the nuclear industry, the annual average effective dose to a worker in the nuclear industry overall has decreased from mSv in the 6975s to about 6 mSv today. However, the annual average effective dose to a coal miner is still about mSv and for other miners about 8 mSv. The mining figures are probably for underground situations.
Because all forms of iodine cross the placenta, pregnant women should take KI (potassium iodide) to protect the growing fetus. Pregnant women should take only one dose of KI following internal contamination with (or likely internal contamination with) radioactive iodine.
Every chemical element has one or more radioactive isotopes. For example, hydrogen , the lightest element, has three isotopes with mass numbers 6, 7, and 8. Only hydrogen-8 ( tritium ), however, is a radioactive isotope , the other two being stable. More than 6,555 radioactive isotopes of the various elements are known. Approximately 55 of these are found in nature the rest are produced artificially as the direct products of nuclear reactions or indirectly as the radioactive descendants of these products.
The main effect of low-level radiation arises from fear, not the radiation itself. People who are conditioned to fear any level of ionizing radiation tend to take action to avoid it, and those actions are sometimes much more harmful than any exposure to low-dose radiation could be*. Concerns about low doses of radiation from CT scans and X-rays are not only misguided, but may lead to suffering and deaths from avoided or delayed diagnosis. Also benefits of nuclear medicine greatly outweigh any harm that might come from the controlled radiation exposure involved.
Find out more about radiation therapy and side effects of radiation therapy. To make the decisions that are right for you, ask your healthcare team questions about radiation therapy.
Do not use dietary supplements that contain iodine in the place of KI (potassium iodide). They can be harmful and non-efficacious. Only use products that have been approved by the . Food and Drug Administration (FDA).
