This is not necessary as the granite is only a small piece and is in a well ventilated area. You would need several tons of granite to emit enough radon to be concerned about and it would have to be in an enclosed area with little ventilation.
No, radon is a naturally occurring radioactive element present in materials containing uranium and thorium (both of which are also radioactive). The most likely source of radon in a building is granite, either in the bedrock underground, in granite countertops and tabletops, granite fireplaces, etc. A microwave cooker is made of metal and plastics and contains no radioactive materials.
No, most granite has between 10 and 20 ppm of uranium,which decays into Radon eventually. Some granite in consumer's home has been found to have 270ppm, even 1,130 ppm of uranium along with the other elements in the radiation decay chain.

The rock in that area is mostly granite, which releases Radon, a radioactive gas.
Radon occurs from alpha decay of solid radium, that is, with the loss of two protons and two neutrons alpha particles are emitted. Felsic, igneous parent bed rock such as granite can contain trace amounts of radium. It is naturally occurring.
Radon is a very heavy gas, several times heavier than air. When radon seeps into a basement as a result of low-level radioactive decay within rocks such as granite, it tends to be trapped there. This is especially true as homes are sealed tighter with insulation and weather strips. A full time ventilation system that circulates air from around the outside of basement floor and walls will stop radon buildup.

Anyone with the requisite knowledge, training and equipment.
Granite is a source of radiation; radon gas can be released from granite if it is drilled into. It is possible that people living on granite could have a higher cancer risk, but I don't think any real proof has been shown to exist.
Almost all granites give off Radon and Thoron gas, both radioactive when they decay down the radiation chain. The dust has silica as well as the radioisotopes present, both can cause lung disease. Have any granite tested for Radon AND Thoron before purchase. Check the radiation levels till you find a low level slab, then have it tested for Radon. Do not trust lab reports unless they were done on YOUR slab. For more info go to solidsurfacealliance.org or forum.solidsurfacealliance.org
It can be. Radon, heavy metal leaching come to mind. For more info go to solidsurfacealliance.org or forum.solidsurfacealliance.org
NO! It must be sealed for countertop use. Radon gas has been found to penetrate up to six feet of solid rock.
Check out www.epa.gov/radon/pubs/citguide.html, that is the official government website for radon testing and a citizen's guide to find the right place to get it done.

Radon is a radioactive monoatomic noble (inert) gas formed by the radioactive decay of Uranium. It occurs naturally and forms high concentrations in cellars, etc. of houses built over granite deposits. There are traces everywhere in the atmosphere but they are virtually undetectable.
