Here are 10 things around us that are radioactive.
Radioactive objects are the sorts of things people generally try to avoid, but it turns out that doing so may not be so easy. The world is full of seemingly benign things that emit radiation.
Here are 10 of them.
Number 10. Exit signs. For them to function during emergencies that involve power outages, they have to be able to glow on their own. The substance that most often allows them to do so is tritium, which gets its illuminating power via a nuclear reaction.
Number 9. Granite countertops. It turns out microwaves are not the only kitchen standbys that emit radiation. As granite ages the naturally occurring particles of radium, thorium, and uranium within it decay, sending radon gas into the air.
Number 8. Kitty Litter. Don’t worry, neither you nor your fluffy little friend are at risk. Trace amounts of radioactive elements exist in the clay and though they’re significant enough to set o
