  • What is Back Ground Radiation. Arial. Front size 60 down to 60 By George Ellis, White arial and black background.
  • Background Radiation

    1. 1. Ba ckgro und Ra diat ion
    2. 2. What is Back Ground Radiation?
    3. 3. <ul><li>Background Radiation is all around us. </li></ul>
    4. 4. <ul><li>We can do little to avoid it. </li></ul><ul><li>Most background radiation comes from natural sources . </li></ul>
    5. 5. These Natural Sources Are
    6. 6. Cosmic Rays <ul><li>Which is radiation that gets to the earth from outer space. </li></ul>
    7. 7. Animals <ul><li>Animals to produce natural levels of Radiation </li></ul>
    8. 8. Rocks <ul><li>Some rocks give away radioactive radon gas. </li></ul>
    9. 9. Soil and Plants <ul><li>The radioactive materials from rocks absorbed by soil and therefore on to plants </li></ul>
    10. 10. <ul><li>While most artificial radiation comes from medical examinations such as X-ray photographs. </li></ul>Artificial Radiation
    11. 11. How Do Rocks Contain Radioactivity
    12. 12. <ul><li>Some rocks contain radioactive substances that produce a radioactive gas called radon. </li></ul>
    13. 13. <ul><li>The pie chart shows the % of the different sources of background radiation that the public are exposed to. </li></ul>
    14. 15. What Is Radon?
    15. 16. <ul><li>Radon is a natural radioactive gas. </li></ul>
    16. 17. It comes from an extremely small amount of uranium that is naturally found in all rocks + soil
    17. 18. What is Radon Detector?
    18. 19. A radon detector is a machine used to detect the presence of radon gas.
    19. 20. Facts about Background Radiation
    20. 21. <ul><li>Is Radon Present in All </li></ul><ul><li>Parts of Italy? </li></ul>
    21. 22. <ul><li>Yes Radon is present in all parts of Italy, but the gas disperses outside so the levels of radon is normally very low. </li></ul>
    22. 23. 2. Is Radon bad in our Lungs
    23. 24. <ul><li>The air we breathe also contains small amounts of isotopes which are one of two atoms having the same atomic number but a different mass number. </li></ul>
    24. 25. This produces radioactivity in our lungs
    25. 26. 3 . Is career conected to background Radiation?
    26. 27. There is lots of career connected to B.R. for example; there is lots of physics and science for example
    27. 28. They are… <ul><li>Building Materials and Background Radiation </li></ul>
    28. 29. <ul><li>Ionizing Radiation </li></ul>
    29. 30. <ul><li>Maximum Work Environment Exposure </li></ul>
    30. 31. Background Radiation The End
