![RADON
• Radon is a chemical element in the periodic table that
has the symbol Rn and atomic number 86.
• Noble gas that is formed by the disintegration of radium,
radon is the heaviest gases and is considered a health
hazard.
• The most stable isotope is Rn-222 which has a half life of
3.8 days and used in radiotherapy.
Radon gas can accumulate in homes and cause lung
cancer [1], causing potentially 20,000 deaths in Europe
alone each year.](https://image.slidesharecdn.com/airpollution-230525110242-b3177d4f/85/AIR-POLLUTION-pptx-19-320.jpg)

- 1. AIR POLLUTION AND CONTROL POWERPOINT PRESENTATION OF AIR POLLUTION
- 3. •Any visible orinvisible particle or gas found in the air that is not part of the original, normal composition.
- 4. Natural: forest fires,pollen, dust storm Unnatural: man-made; coal, wood and other fuels used in cars, homes, and factories for energy
- 6. DEFINITION • There isa gas, liquid or particles contained in the air so that the change and affect the life or other materials. • The materials are suspended in the air and a negative impact on humans, plants and animals. • This is due to these materials will enter the body through breathing and can block the flow of oxygen into the blood vessels. • This can cause various diseases such as cramps, cancer, asthma, cramps, and anemia. Dust, smoke, mist, vapor or other substances that can block eyesight is different form of air pollution
- 10. Pollutants Pollutants can beclassified as either primary or secondary Primary pollutants:-Are substances directly emitted from a process, such as the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories.
- 11. Pollutants Secondary pollutants:- Arenot emitted directly. Rather, they form in the air when primary pollutants react or interact. An important example of a secondary pollutant is ground level ozone.
