The Radioactivity Of Marble

Both granite and marble are naturally occurring materials that were formed millions of years ago similar to minerals.

The radioactivity of marble.

However some articles have circulated that claim granite is a source of harmful radiation specifically radon. 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. 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.

These range from natural materials such as wood marble and granite to engineered products such as quartz stone. Some building materials such as granite brick marble and other items contain natural radioactivity. By curiouspost august 23 2015. One of the top picks for us homeowners is granite because it is durable and beautiful as well as affordable.

Granite and marble do emit tiny but noticeable amount of radiation in different proportions.
