Here are a couple of notes: Waves- electromagnetic spectrum ultraviolet: dangerous as you get to higher frequency light the light becomes more dangerous opposite as you get to lower frequency ultraviolet can ionize and effect dna can cause cancer (ionizing radiation) microwave has less energy than light but has more photons phone has 3 milliwatts same as microwave but has 600 watts mobile phones photons don′t have enough energy to change dna radiation works on the inverse square law: if you double distance is 1/4 of the risk 3 tames is 1/9 three factors: proximity-distance (explain inverse square law) type of radiation- ionizing and non ionizing (not sufficient energy to change DNA Power of radiation- phone vs microwave You have to choose a side describing is achieved explaining is merit discussion is excellence below is a example of what it should look like
