RADIATION
FACT SHEET
What is radiation?
Radiation is a form of energy that is present all around us.
How can you be exposed to radiation?
You are exposed to small amounts of radiation every day, both from natural and man-made sources. The natural sources are elements in the soil or cosmic rays from the sun. Some man-made sources include electronic and medical equipment. Nuclear weapons testing may also result in radiation exposure.
How soon does an exposed person show adverse health effects?
The timeframe for symptoms will depend on the type, route of exposure, and length of time of exposure to radiation.
What are the adverse health effects from radiation?
Radiation can affect the body in various ways and the adverse health effects may not be apparent until years later. If you are exposed to low doses of radiation it may lead to the risk of developing cancer or adverse health effects later in life. If you are exposed to very large doses of radiation, it may cause death within a few days or months.
How I can protect myself during a radiation emergency?
If there is a release, the local authorities will monitor the levels of radiation and determine what protective actions to take. Listen to the radio or television for any information and instructions. You may be advised to "shelter in place", which means to stay in your home or office. If you are advised to "shelter in place", you should do the following: close and lock all doors and windows, turn off fans, air conditioners, and forced-air heating units that bring in fresh air, close fireplace dampers, bring pets inside, move to an inner room and keep your radio tuned to a local news network. If advised to evacuate, leave the area as quickly as possible. Take your pets only if you are using your own vehicle and going to a place you know will accept animals. If you have an injury or become ill, call 911 for medical attention right away. Do not drive yourself to the hospital as you may become very ill on your way.
