Low frequency radiation is a very common form of radiation in people's lives, two examples being cell phones and car radar emitters, used as safety features. Some studies have raised concerns over cell phones, but the available literature remains inconclusive. I am testing E.coli using the Ames test, a test for mutagenic substances, and fruit flies, using both cell phones and radar guns. I hypothesize there will be no change in the rate of mutations among test specimen when exposed.
