The radioactivity of marble.
One of the top picks for us homeowners is granite because it is durable and beautiful as well as affordable.
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 marbles barely register on sensitive geiger counters and the radiation emitted barely creeps above the background radiation we experience everyday from natural sources.
Both granite and marble are naturally occurring materials that were formed millions of years ago similar to minerals.
Granite and marble do emit tiny but noticeable amount of radiation in different proportions.
These range from natural materials such as wood marble and granite to engineered products such as quartz stone.
However some articles have circulated that claim granite is a source of harmful radiation specifically radon.
Some building materials such as granite brick marble and other items contain natural radioactivity.
Yes it is true.
