Transcript of "NGI-Radiation Awareness"

  1. 1. oasis International Training Center Presents
  2. 2. TSP HSE DEPARTMENT RADIATION AWARENESS
  3. 3. RADIATION AWARENESS DANGER RADIOACTIVE RADIATION
  4. 4.  Labeling, Transport , Storage  What is radiation?  Effect on Health  Protection against exposure  Conclusion RADIOGRAPHY
  5. 5. Radiation is all around us. It occurs naturally or can be produced artificially . Ex.: light, lasers, the sun, x-ray machine, TV transmitters and radioactive material. Radiation : energy emitted from a source as waves or particles, which is transmitted through space.  What is it?
  6. 6. THE PHYSICS OF RADIATION RADIATION AWARENESS
  7. 7. TYPES OF IONISING RADIATION
  8. 8. Exposure : measure of the ionisation produced in air by gamma rays. Dose : measure of energy deposited by radiation in a material (measure of the ionisation produced in air by gamma rays) or of the relative biological damage produced by that amount of energy given the nature of the radiation.  Effect on Health RADIATION AWARENESS
  9. 9. Mechanism of damage : radiation causes atoms and molecules to become ionised or excited. It can result in damage to molecules which regulate vital cell processes. Interaction of radiation with matter : the relative amount of damage to the cell and tissue of a person exposed to radiation depends on the energy deposited. Biological effects depend on dose and time. RADIATION AWARENESS  Effect on Health
  10. 10. <ul><li>Effect of acute high radiation dose: from disruption of the function to death. </li></ul><ul><li>Effect of low radiation doses: development of some form of cancer. </li></ul>• Gamma rays may cause damage to deep-seated organs and tissues without being in the body. They are internal & external hazard to the body. • Gamma rays are high penetrating. None of the 5 human senses are able to detect ionising radiation.  Effect on Health RADIATION AWARENESS
  11. 11. IONISING RADIATION - BIOLOGICAL EFFECTS 3 types of effects from ionising radiation RADIATION AWARENESS
  12. 12. TSP HSE DEPARTMENT Exposure to radiation is minimized by applying the principles of external radiation protection: <ul><li>Keep TIME of exposure to a minimum. </li></ul><ul><li>Maximize the DISTANCE between yourself and the source of radiation as much as possible. </li></ul><ul><li>Keep adequate SHIELDING material between the source of radiation and yourself. </li></ul> Protection against exposure RADIATION AWARENESS
  13. 13. IONISING RADIATION - DOSE RATES RADIATION AWARENESS
  14. 14. CONTROLLED AREA The controlled area should be demarcated by a physical barrier, e.g. a rope or bunting at the 7.5 micro Sievert per hour boundary. Flashing lights should also be used to mark the controlled area where the work is carried out. When establishing boundaries, monitoring should be carried out at, above and below floor level. Access should be restricted and suitable warning signs displayed. RADIATION AWARENESS  Protection against exposure
  15. 15. <ul><li>SAFE WORKING PRACTICES </li></ul><ul><li>Procedure must be prepared, including contingency plan. </li></ul><ul><li>Appointed Radiation Protection Supervisor. </li></ul><ul><li>Permit To Work. </li></ul><ul><li>Work carried out at optimum times when practicable. </li></ul><ul><li>Controlled area marked at 7.5 micro Sv / h boundary using rope barriers or bunting. </li></ul><ul><li>Suitable warning notices to be displayed. </li></ul><ul><li>Restricted access. </li></ul><ul><li>Use of flashing lights whilst shooting. </li></ul><ul><li>Monitoring: personnel dosimeter, film badges. </li></ul> Protection against exposure RADIATION AWARENESS
  16. 16. IONISING RADIATION - SAFE WORKING PRACTICES RADIATION AWARENESS
  17. 17. MARKING : All equipment and packages containing radioactive substances must be labeled with the radiation trefoil. STORAGE : Stores should be properly constructed, e.g. strong boxes in fenced off areas (bomb pits) or in self-contained protective boxes, located as far away from personnel as possible. All stores should be regularly monitored. Radiation level at the nearest accessible point should be less than 7.5 micro Sievert / hour  Labeling, Transport and Storage RADIATION AWARENESS
  18. 18. Here, radioactive substances are available as sealed sources. Sealed sources are held within a robust container designed to isolate the source from the external environment. Radioactive substances, when not in use, must be stored in a locked, protective receptacle, suitably labeled, solely reserved for radioactive substances and designed in accordance with current legislation.  Labeling, Transport and Storage RADIATION AWARENESS
