What does installing granite and knowing the chemical make up of granite have to do with each other?
Most installers I know don't care about the chemical make up, they know how to cut it, take care of it and put it in.
it has to do with knowing it is sealed not raw unsealed granite thats used in the counter tops and cutting boards, hence the first hand expirience is relevant. it doesnt have anything to do with knowing the composition of it.

Radon can cause cancer, although there is debateable evidence in whether or not you will get it from your home. There are radon maps available through USGS. The radon kits most people can buy, are like the mold kits and lead based paint tests. Pretty much crap. In some states you must be liscensed to do radon testing. The only way to correctly evaluate exposure is through a passive sampling that lasts several months

Granite is an inert stone, it is neutral, there is no element in it's make up that would dissolve, it has no halflife. there is no harm in putting it in your aquarium, people have been useing it for many years in salt and fresh without ill results, you are more likely to mercury poison your fish from clams than with arsenic from granite, the radon gas that is detected in granite mines is released from the digging of the mine not from it being trapped in the granite it's self, the whole eastern coast is granite, you can tell me that even with the size of the ocean there wouldn't be problems in the intercoastal areas, there is alot of granite, if there is a fish living in close proximity to the stone, eatting off the stone, one would definately see affects, even if it is being washed away things would still be exposed to it.

that is just not true.the quartz in it IS inert but there are other elements
"Granites are formed of an aggregate of crystals which are molded together without any interspace between them or which enclose one another. The magnificent crystallinity of granite is a striking characteristic." Geology of Granite, E. Raguin, London, 1965 p.3
It is accurate to speak of "granites," because many varieties of the stone exist. While they differ in color, texture and crystalline structure, the granites have three essential minerals in common:
Feldspar (50% or greater) (soluble and a source of silicates probably one of the best reasons not to use granite as it will fuel diatomic growth, even if arsenic contamination is not a worry)Quartz (25-40%)
Mica (3-10%)
These minerals occur in different proportions, giving each granite its own color, texture and structural characteristics. In addition, hornblende, magnetite, hematite, pyrite, zircon, garnet, corundum and other minerals may be present in smaller amounts, adding to the unique coloration and texture of each granite deposit. In supplying granite for all large building or complex of buildings, it is essential that the stone be consistent in color and texture. To assure this, each granite color must be quarried from the same deposit. With natural material like granite, a certain amount of "movement" or grain in the stone must be expected. Many people find this flow and blending of colors to be the most compelling reason for using granite.

the mica in granite is also harmfull often containing many heavy metals
Biotite is the most common of the micas, containing iron and/or magnesium impurities substituting for octahedral aluminum. Muscovite is the pure potassium mica, containing no impurities. Fuchsite mica is a chromium rich variety of muscovite where chromium cations substitute for some of the octahedral aluminum in the muscovite crystal structure. The chromium impurities in fuchsite are responsible for its emerald green color. Lepidolite mica is a lithian mica where an occaisional lithium cation substitutes for some of the octahedral and tetrahedral aluminum in the mica crystal structure. Zinnwaldite is a lithian ferrous mica, where lithium and iron cations substitute for some of the octahedral and tetrahedral aluminum.
