(Ionizing Radiation Exposure)
by Amy Scholten, MPH
Radiation is energy that is sent out from a source. It can be found in nature. It can also be manmade. Radiation exposure is when a person is exposed. It can affect health, depending on the type and amount.
There are two types:
Ionizing radiation can injure cells. It is linked to cancer and other health problems.
Ionizing radiation can come from:
The risk is higher for those who are near sources of radiation.
Health problems do not happen in everyone. The higher the exposure, the more likely there will be problems.
CT scans give more radiation thanx-rays. However, the dose and risk for health problems is low with both.
High doses of radiation over a short period of time may cause:
Low levels may not cause symptoms. Sometimes cancers grow years after exposure. They may be:
The doctor will ask about your symptoms and health history. A physical exam may be done. Tests may be done on blood, urine, and stool.
A device may be used to check the amount of radiation in the body.
Treatment is based on the dose of exposure, the source, and the symptoms. The goal is to ease symptoms and reduce problems. It may include:
The risk of exposure may be lowered by:
