The MOST RADIOACTIVE Places on Earth
Radiation is frightening. At least, certain types of it are. Meaning, if Geiger counter doesn't go off near mobile phone , or the Wi-Fi router or microwave . That's because Geiger counter only measures ionizing radiation , that is radiation with enough energy to rip electrons off atoms . And it's measured in units called sieverts . If you're exposed to more than 2 sieverts all at once, you'll probably die shortly after that. But we're exposed to low levels of ionizing radiation all the time. Bananas for example are rich in potassium and some of that potassium is naturally radioactive. So when you eat a banana, you're actually exposed to about 0.1 microsieverts of radiation. That's one per ten millionth of a sievert. Let's use a banana for scale of radiation doses. You know, since people eat bananas we become radioactive too. So you're actually exposed to more radiation if you sleep next to someone than if you sleep alone. But don't w...
