Government and industry officials often assess the potential danger of our exposure to radiation, whether from cell phones or nuclear reactors, in terms of how it compares to radiation from other sources–but that method overlooks the cumulative effects of radiation.
While it’s true we are bombarded with low levels of radiation every day–from the soil, the sun, even household appliances–many medical experts say no amount of radiation is truly safe, because radiation builds up in our bodies over time and eventually may lead to cancer and other diseases.
We’re exposed to a lot of radiation we simply can’t avoid. All the more reason to not take radiation exposure for granted, and to protect ourselves from radiation whenever we can.
