The Radioactivity Of Marble

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.

The radioactivity of marble.

However some articles have circulated that claim granite is a source of harmful radiation specifically 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. Although the marbles emit beta particles and gamma rays which are dangerous at high levels they only give off a small number of these radioactive decay products. Both granite and marble are naturally occurring materials that were formed millions of years ago similar to minerals.

Generally these substances contain traces of radioactive elements like uranium thorium and their daughter products like radium polonium and radon. Granite and marble do emit tiny but noticeable amount of radiation in different proportions. Some building materials such as granite brick marble and other items contain natural radioactivity. Yes it is true.

Many homes contain decorative rock and stone such as granite and marble.
