Many homes contain decorative rock and stone such as granite and marble.
The radioactivity of marble.
By curiouspost august 23 2015.
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.
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.
Generally these substances contain traces of radioactive elements like uranium thorium and their daughter products like radium polonium and radon.
Yes it is true.
Granite and marble do emit tiny but noticeable amount of radiation in different proportions.
