They make a house look much more modern. I understand it can increase your home value by at least $3000.
Granite weighs an average of about 20 pounds per square foot, so a 5' by 8' (40 square feet) piece of granite would weigh approximately 800 pounds.
How much dose 3 square of roofing cover
About 18# per sq ft

the geiger counter detects radiation. when a radiation particle (alpha, beta gamma) goes through it clicks. the amount of clicking is how much radiation there is.
Granite counter tops offer many advantages over a standard counter top. The material is very strong and will surely last much longer and take more abuse than a laminate counter. Granite is also a very tight material and after polished and sealed it is very easy to clean, and resists stains.
The cost will vaey on size on your counters and kind of granite. It is about $4.00 per square foot, for black granite 3/8" thick for materials only.
Your looking to pay around $29 per sq ft with installation for granite countertops.
You are exposed to a mild dose of radiation
Not directly, but it allows them to monitor how much dose of radiation they have received over a period of time, so they can look at it and check they haven't received too much dosage.
The scientific unit of measurement for a dose of radiation, which is also called an effective dose, is the millisievert (mSv). This is also at times measured in rads, rems, roentgens and sieverts. For an X-ray of a limb, the typical effective dose is 0.001 mSv. This is a comparatively small dose, and often talked about in relation to how much natural radiation from the earth to which it compares. In this case, it is equal to the natural background radiation you would get in less than one day.
A granite countertop that is thicker will be more durable, but the cost increases linearly with the thickness. The installation cost won't change much, because that's mostly labor rather than materials. Granite counter tops average about 1 inch in thickness. Any thinner and the granite is much too brittle. Any thicker and the costs sky rocket due to increased weight and materials cost.
Geiger counters for measuring how much radiation is going on *now*. Dosimeters are carried by the astronauts in order to determine their total radiation dose during the mission.
1 Millirem. Which is less than their yearly dose.
Granite counter tops cost 48$-150$ per sq. foot Granite tile cost $4-$20 per sq. foot. The price of granite very's so much that it mostly depends on the type of granite. Example:Granite tile price's at home depot:$5.00 sq. foot for black granite$7.00 sq. foot for Brazilian green granite$10.99 sq. foot for tan brown graniteand for counter tops, it cost $48.00 sq foot. at the lowest.Note: prices are of 6/28/10 this is not from home depot. And the price of granite changes from year to year.
