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

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.
A Geiger counter or a dosimeter can be used to measure radiation in space. These instruments detect the presence and intensity of various types of radiation, such as gamma rays or cosmic rays, that can be found in space.
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
A rad is a unit of absorbed radiation dose, but it is not commonly used anymore. The International System of Units now uses the gray (Gy) as the standard unit for absorbed radiation dose. 1 rad is equal to 0.01 gray.
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.
A Geiger counter, invented by Hans Geiger, detects ionizing radiation such as alpha and beta particles, gamma rays, and X-rays. It works by measuring the ionization produced in a gas by the radiation, producing an audible click or visual display to indicate the presence of radiation.
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.
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.
1 Millirem. Which is less than their yearly dose.
