 Show Internal ContaminationInternal 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. Other types are eliminated from the body in blood, sweat, urine, and feces. Radioactive ContaminationRadioactive 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. A contaminated person has radioactive materials on or inside their body. People who are externally contaminated with radioactive material can contaminate other people or surfaces that they touch. For example, people who have radioactive dust on their clothing may spread the radioactive dust when they sit in chairs or hug other people. People who are internally contaminated can expose people near them to radiation from the radioactive material inside their bodies. The body fluids (blood, sweat, urine) of an internally contaminated person can contain radioactive materials. Coming in contact with these body fluids can result in contamination and/or exposure. What happens if you are exposed to a radioactive person?Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.
What should you do if you are exposed to radioactive materials?Stay inside. Close and lock all windows and doors. Go to the basement or the middle of the building. Radioactive material settles on the outside of buildings; so the best thing to do is stay as far away from the walls and roof of the building as you can.
What is the most severe response to radiation exposure?Cardiovascular/central nervous system sickness is the type of ARS produced by extremely high total body doses of radiation (greater than 3000 rads). This type is the most severe and is always fatal.
What precautions should be taken when working with radioactivity?Conducting the Research. Use spill trays and absorbent covering.. Use fume hoods for handling potentially volatile material.. Use glove box for handling large quantities of volatile material.. Wear laboratory coat, disposable gloves, and laboratory safety glasses.. Use gloves appropriate for the chemicals to be handled.. |
