Many homes contain decorative rock and stone such as granite and marble.
The radioactivity of marble.
One of the top picks for us homeowners is granite because it is durable and beautiful as well as affordable.

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