Is Decomposed Granite Radioactive
Decomposed granite is rock of granitic origin that has weathered to the point that it readily fractures into smaller pieces of weak rock.
Is decomposed granite radioactive. He s sure he has made a rich strike. Granite is the most abundant type of natural stone in the world. Decomposed granite is the completely natural derivative of granite. These trace concentrations may vary from stone to stone or even within a single slab of granite.
Further weathering produces rock that easily crumbles into mixtures of gravel sized particles sand and silt sized particles with some clay eventually the gravel may break down to produce a mixture of silica sand silt particles and clay. The amount of radiation emitted from granite can vary depending on the natural uranium and or thorium concentration. So do other items in our households. Granite contains radioactive materials.
This decomposed granite crumbles into various sizes of particles and can be further crushed and screened to specific sizes for different project needs. Granite like any other stone may contain veins of naturally occurring radioactive elements like uranium thorium and their radioactive decay products. It isn t a surprise that granite emits radiation. When granite erodes and endures weathering over time it easily starts flaking and crumbling away from its parent source.
The radioactivity of granite as a matter of fact has led to much confusion on the part of week end prospectors.
