Hello Guest, welcome to the initial stages of our new platform! You can find some additional information about where we are in the process of migrating the board and setting up our new software here

We have a lot to be concerned about. Some people say small amounts of radiation are good for you while others say there is no amount of radiation that is safe. So why can’t someone make it easy to decide when or if you should worry about radiation exposure? That is exactly what we’re going to do here—help by providing the facts. If you want additional information on why there is disagreement about the effects of low-level radiation, we have provided this in the section titled "Controversy."

It isn’t a complete guessing game, though. Because radiation has been studied so much, there are some things we can say with certainty that apply to a majority of the population. We can say that for a small radiation dose (<100 mSv), the risk of cancer is very small, too small to have any observable health impact in the population of the United States. We know that if the radiation dose is quite large and given in a short period of time, like the 10,000 mSv in the chart above, it will cause an individual to be very sick and die.

The health effects listed above are for a radiation dose to the entire body. If the radiation is given to a smaller area of the body, there are other effects that may occur, but illness or death is not expected unless noted:

Radiation specialists use the unit “rem” (or sievert) to describe the amount of radiation dose someone received. We are going to use that unit throughout the sections. Without getting into technical specifics about that unit, it is enough to know that it indicates a measure of how much radiation energy is absorbed in our body. And, as we will see in other sections, the total energy that is absorbed and its effectiveness in causing change is the basis for determining whether health effects may result.

Why do some people say all radiation exposure is bad and others say it can be okay? Even the scientific community differs on the answer to the question of low radiation doses and health effects. Radiation can cause biological changes in cells when they are outside the human body, and these can be seen in a laboratory even when the dose is small. However, these changes are not seen or cannot be related to health effects in humans. The fact that changes can occur may make some people believe all radiation is bad and the fact that this is not related to human health effects may make others believe it is safe at low levels. The human health effects that have been observed have been when individuals or groups have received larger doses of radiation (more than 500 mSv) from events like those due to military uses of nuclear weapons, accidents, and uses of radiation in medicine for therapy.

If a population receives a radiation dose of 1,000 mSv in a short period of time, we expect health effects in some of the people who were exposed. However, many who receive a dose at that level will not have any long-lasting health effects. This is like so many other things in our lives. If we eat a high-cholesterol, high-fat diet, some of us may end up with heart disease. But that isn’t true for everyone; some can eat this way for a lifetime and not have any heart-disease symptoms.
