Many homes contain decorative rock and stone such as granite and marble.
These marbles barely register on sensitive geiger counters and the radiation emitted barely creeps above the background radiation we experience everyday from natural sources.
Generally these substances contain traces of radioactive elements like uranium thorium and their daughter products like radium polonium and radon.
Both granite and marble are naturally occurring materials that were formed millions of years ago similar to minerals.
Some building materials such as granite brick marble and other items contain natural radioactivity.
Granite and marble do emit tiny but noticeable amount of radiation in different proportions.
However some articles have circulated that claim granite is a source of harmful radiation specifically radon.
