What is radioactive contamination?
Radioactive Contamination. Radioactive contamination occurs when radioactive material is deposited on or in an object or a person. Radioactive materials released into the environment can cause air, water, surfaces, soil, plants, buildings, people, or animals to become contaminated.
How to avoid getting radioactive material in your body?
Keep people away from it to reduce their exposure to radiation. Keep cuts and abrasions covered when handling contaminated items to avoid getting radioactive material in them. Wash all of the exposed parts of your body using lots of soap and lukewarm water to remove contamination. This process is called decontamination.
How to reduce radiation exposure?
How You Can Limit Contamination 1 Get out of the immediate area quickly. Go inside the nearest safe building or to an area to which you are directed by law enforcement or health officials. 2 Remove the outer layer of your clothing. If radioactive material is on your clothes, getting it away from you will reduce the external contamination and decrease the risk of internal contamination. It will also reduce the length of time that you are exposed to radiation. 3 If possible, place the clothing in a plastic bag or leave it in an out-of-the-way area, such as the corner of a room. Keep people away from it to reduce their exposure to radiation. Keep cuts and abrasions covered when handling contaminated items to avoid getting radioactive material in them. 4 Wash all of the exposed parts of your body using lots of soap and lukewarm water to remove contamination. This process is called decontamination. Try to avoid spreading contamination to parts of the body that may not be contaminated, such as areas that were clothed. 5 After authorities determine that internal contamination may have occurred, you may be able to take medication to reduce the radioactive material in your body.

How does internal contamination occur?
Internal contamination occurs when people swallow or breathe in radioactive materials, or when radioactive materials enter the body through an open wound or are absorbed through the skin. Some types of radioactive materials stay in the body and are deposited in different body organs.
What is external contamination?
External contamination occurs when radioactive material, in the form of dust, powder, or liquid, comes into contact with a person’s skin, hair, or clothing. In other words, the contact is external to a person’s body.
What is the process of decontamination?
This process is called decontamination. Try to avoid spreading contamination to parts of the body that may not be contaminated, such as areas that were clothed. After authorities determine that internal contamination may have occurred, you may be able to take medication to reduce the radioactive material in your body.

What are the sources of radiation?
And yet, the cell phones, cell phone towers, cordless phones, as well as TVs, computers, microwave ovens, broadcast antennas, military and aviation radars, satellites, and wireless internet are all sources of radiation. And so are the common medical X-Rays. Considering this, the picture of radiation pollution significantly expands.
How does radiation affect people?
Depending on the amount of radiation to which we are exposed and the sensitivity of each exposed person, the effects of radioactive pollution can vary significantly between individuals. While the exposure to high amounts of radiation generates almost immediately chronic diseases, cancer or even sudden death in rare cases of extreme pollution, small amounts of radiation can cause diseases that are not so serious and develop over the course of time. The risk of developing cancer increases with the dose of radiation, but lower doses of radiation can also cause cancer after years of exposure.
What type of pollution occurs when certain experiments involving dangerous substances fail?
Accidental pollution. Accidental radioactive pollution is the type of pollution that occurs when certain experiments involving dangerous substances fail, and the substances used for experimentation get out of control.
What are radioactive materials?
Radioactive materials are those materials or elements that emit radiation, thus they are not stable and get transformed into other radioactive or non-radioactive materials. The harm that they can cause depends on the radioactive elements and their half time function (the time needed for their concentration to be reduced to half due to radioactive decay processes). Basically, the higher the half-time, the lower the effects on human health. Radioactive elements with a short and very short half-time pose a serious threat to human health because of their hazardous effects. Most of the radioactive materials have half-lives of hundreds of thousands of years and, once generated, may persist in the environment for a very long time.
