What is an example of radioactive contamination?
How Radioactive Contamination Is Spread. 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.
What are examples of radioactive substances?
Radionuclides (radioactive materials)
- Cesium.
- Cobalt.
- Iodine.
- Ionizing Radiation.
- Plutonium.
- Radium.
- Radon.
- Strontium.
What are the two most common types of radioactive contamination?
The sources of radioactive pollution can be classified into two groups: natural and man-made. Following an atmospheric nuclear weapon discharge or a nuclear reactor containment breach, the air, soil, people, plants, and animals in the vicinity will become contaminated by nuclear fuel and fission products.
Which are radioactive pollutants?
Radioactive pollution of water, water sources, and air space is the result of radioactive fallout from the cloud of a nuclear explosion. Radionuclides are the main sources of pollution; they emit beta particles and gamma rays, radioactive substances.
What is radioactive contamination GCSE?
Contamination. Occurs when an object is exposed to a source of radiation outside the object. Occurs if the radioactive source is on or in the object. Doesn’t cause the object to become radioactive.
What are some examples of radiation in everyday life?
Radiation Examples
- ultraviolet light from the sun.
- heat from a stove burner.
- visible light from a candle.
- x-rays from an x-ray machine.
- alpha particles emitted from the radioactive decay of uranium.
- sound waves from your stereo.
- microwaves from a microwave oven.
- electromagnetic radiation from your cell phone.
What are 3 examples of man made radiation sources?
Small amounts of man-made background radiation is attributable to consumer products like color televisions, smoke detectors, gas lantern mantles, natural gas heating and cooking fuel, and mining and agriculture products, such as coal, granite and potassium salt.
Which of the following is the most radioactive pollutants?
Strontium – 90 is a highly dangerous radioactive pollutant.
- Strontium-90 (90Sr) is a radioactive isotope of strontium produced by nuclear fission, with a half-life of 28.8 years.
- It undergoes β− decay into yttrium-90, with a decay energy of 0.546 MeV.
What is radioactive pollutants in water pollution?
Radionuclides found in drinking water are members of three radioactive series, uranium, thorium, and actinium and include the naturally occurring elements radium, uranium, and the radioactive gas radon. These contaminants may cause different types of biological damage.
What are the hazards of radioactive contamination?
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 is the difference between radiation and contamination?
Radiation is a type of energy moving in the form of particles or waves. Ionizing radiation is energy emitted from unstable atoms. Contamination – Unwanted radioactive material in or on the body, or spread about the environment (radioactive material in unwanted places).
What are four examples of radiation?
Examples Of Radiation
- Radio waves.
- Microwaves.
- Visible light.
- Infrared light.
- Light from the sun.
- Lasers.
What are some common sources of radiation in your home?
9 Common Sources of Radiation in the Home and Workplace
- Television Sets. Watching 4.5 hours of television per day exposes the viewer to one mrem of x-ray radiation.
- Computer Monitors.
- Drinking Water.
- Natural Gas.
- Cellphones.
- Microwave Ovens.
- Soils.
- Radon Gas.
What are the major types of radioactivity?
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects.
