About EMF, Plainly

EMF, Plainly is a handful of guides for people who want to know what their phone, Wi-Fi router, earbuds or laptop actually gives off, and which changes lower their exposure.

Every number on these pages has a named source. Most come from U.S. agencies like the FDA, FCC and FTC, or from the device maker's own RF exposure filings, and a few come from published lab studies. If a figure is a worked example and not a measurement, the page says so and shows the math.

We don't make health claims of our own, and nothing here is medical advice. If you have symptoms, see a doctor.

Some guides point to product types that do what they say on the box: wired earbuds have no radio, and a well-sealed pouch keeps a phone off the network while it's inside (a test call tells you whether yours does). We don't recommend stickers, chips or pendants sold as radiation shields. In 2011 the FTC said there is no scientific proof that such shields significantly reduce exposure, and we haven't found anything since that changes that.
