The safety of mobile phones (U. S. cell-phones) seems to face new questions after British researchers found that microwave emissions can affect the health of earthworms in unexplained ways.
The larvae of tiny soil worms called nematodes grew faster and became more (1) after they were (2) for a long time to weak microwave radiation, of the (3) strength and frequency as that (4) by mobile phones, they found.
Why this occurred is (5) , and there is no evidence that human health is also affected. But, they warn, the finding challenges the standards which (6) whether a mobile is safe or not.
These standards are based on whether the radiation is strong enough to cause a batch of (7) to warm up. Heat causes the chemical bonds in cells to (8) , a disruption that can be a potential (9) for cancer.
