Hey Ms Hamilton sorry it's not on Prezi or a slide show or anything but this is the best i can do :) hope i pass.

__ Does the use of cell phones increase the risk of brain tumours in humans? __ Cell phones emit RF which is a form of electromagnetic radiation. Electromagnetic Radiation has two types: lionizing electromagnetic radiation, which has a high frequency and non-ionizing electromagnetic radiation. RF energy which cell phones emit is a type of non-ionizing electromagnetic radiation. Ionizing Radiation, which is x-Rays emit, can be a cancer risk. There is currently no conclusive evidence that the non-ionizing radiation emitted by cell phones can pose a cancer risk.

Studies have shown that the amount of RF energy put out by cell phones is much too low to cause significant increase in body temperature or tissue heating. It still needs further study to determine what effects, if any, low level non-ionizing RF energy has on the body and whether it poses a health danger. There is concern that RF energy produced by cell phones may affect the brain and other tissues in the head because hand held cell phones are usually held close to the head. Researchers have focused on whether RF energy can cause brain tumours Bibliography [|http://www.cancer.gov/cancert opics/factsheet/Risk/cellphones] I think that cell phones do not increase the chance of having a brain tumour because with all the research I have done there are a lot more sites suggesting that there is next to no evidence. With the amount of people that use cell phones these days I think that it would be quite obvious if cell phones did increase the chance because there would be a lot more people getting diagnosed.
