  1. Cell phone radiation • Objectives: • A.)The source and type of cell phone radiations • B.) Their health impacts & ways to reduce them and/or their effects • C.)An experiment that show how the thermal image of a person looks like before and after a long phone call. • By: Abdulrahman, Ali and Sobhi

  2. Sources and types of cell phone radiation

  3. Sources of cell phone radiation: • When talking on a cell phone, a transmitter takes the sound of your voice and translates it onto a continuous sine wave. A sine wave is just a type of continuously varying wave that radiates out from the antenna and alters evenly through space. • . Once the prearranged sound has been placed on the sine wave, the transmitter sends the signal to the antenna, which then sends the signal out. (howstuffworks, 2018)

  4. Cell phones have low-power transmitters in them. Most car phones have a transmitter power of 3 watts. A handheld cell phone operates on about 0.75 to 1 watt of power. • The position of a transmitter inside a phone varies depending on the manufacturer, but it is usually in close proximity to the phone's antenna. • The radio waves that send the encoded signal are made up of electromagnetic radiation propagated by the antenna. • The function of an antenna in any radio transmitter is to launch the radio waves into space; in the case of cell phones, these waves are picked up by a receiver in the cell-phone tower. (howstuffworks, 2018)

  5. SAR of different cell phone types • specific absorption rate (SAR), which is a way of measuring the amount of radio-frequency energy that is absorbed by the human body. (CNET,2014)

  6. Impacts of cell phone radiation on humans

  7. Ionizing and non-Ionizing Radiation • Ionizing Electromagnetic energy that can knock out an electron that breaks chemicals bonds in your body and damage DNA because it has High Frequency which means it transmits high energy Causing cancer and other Damages to the body For example: Gamma rays UV (Forbes,2018)

  8. Non-Ionizing However is the opposite, Electromagnetic energy that cant knock out an electron because it has low frequency and which means it transfers low energy Examples: Cell phones Microwaves (Forbes,2018)

  9. The WHO/ International Agency for Research on Cancer (IARC) • IARC Classifies radiofrequency electromagnetic fields as Possibly Carcinogenic to humans Group 2B: • The agent is possibly carcinogenic to humans (WHO)

  10. Effects of non-ionizing radiation • Brain • Breast cancer • glucose metabolism • Blood pressure • Reproductive organs • Plants • Animals

  11. Brain • Many studies said that cell phone radiation doesn’t cause cancer but due to the long exposure overtime of cell phones this may cause cancer • Cell phone radiation can cause glioma ( brain tumor) • As if cooking the brain, heat from the ear to inside the brain as microwave • Children have more risk in getting or absorbing radio frequency waves because they have thinner skulls (National Cancer Instuite,2018)

  12. Glucose metabolism • The human brain has a metabolic reaction to a mobile phone frequency , glucose is consumed on the side where the phone was activated (National Cancer Instuite,2018)

  13. ( The Truth About Cancer,2018)

  14. Solutions or ways to reduce them • Distance is your friend • Avoid using your cell phone when the signal is weak • Do not sleep with your cell phone powered on • Decrease time • Airplane mode • Covers or shield • Speaker mode • Don’t use it in surrounded areas or for example: cars ( Environmental health trust,2018)

  15. Thermal image experiment • Background information: • Mobile phones have been known for their emission of dangerous radiation. This is said to be caused by all the electromagnetic and microwave signals released, along with the lithium batteries. • Further more, we will analyze an experiment conducted to prove that mobile phone have a radioactive effect on the humans brains

  16. Hypothesis: • Performing a phone call will cause the body temperature to increase due to the radiation it emits. • Experiment: Using a thermal imaging camera, the before and after phone call images of a man will show whether the body temperature will increase or remain constant

  17. This is image was taken before the phone call, and it shows normal body temperature. (name h. h., 2011)

  18. This image was taken after performing a 15 minute phone call. It shows that the body temperature has increased greatly specially around the ear regions where the phone is held close to (name h. h., 2011)

  19. Conclusion: This experiment has proved that a phone call can increase the body temperature due to radiofrequency. Thus, this increase in temperature can lead to multiple problems ranging from dizziness to a brain tumor
