All granite, and most earthen materials, contain trace amounts of uranium and radium, emit gamma radiation and release radon gas.
Granite, like any other stone, may contain veins of naturally occurring radioactive elements like uranium, thorium, and their radioactive decay products. These trace concentrations may vary from stone to stone, or even within a single slab of granite.
Quartz and granite contain varying amounts of uranium, thorium, and potassium, which are naturally radioactive. Uranium and thorium decay to a radioactive gas, radon, which in turn decays to other radionuclides.
Some granite used for countertops may contribute variably to indoor radon levels. Some types of granite may emit gamma radiation above typical background levels.
Alpha radiation has very little penetrating ability and, depending on how the surface of the granite has been treated, may be present in very small intensities or not measurable at all.
Shielding: Barriers of lead, concrete, or water provide protection from penetrating gamma rays. Gamma rays can pass completely through the human body; as they pass through, they can cause damage to tissue and DNA. and x-rays.
Building materials, such as brick, marble and granite, contain very low-levels of naturally-occurring radioactivity. However, these materials can emit radon as the materials decay, which can elevate the indoor radon levels in your home.
Avoid countertops that are largely plastic such as cultured marble, solid surface, and those that introduce formaldehyde, like laminate.
Answer: All types of houses can have radon problems-old homes, new homes, drafty homes, insulated homes, homes with basements and homes without basements. Construction materials and the way the home has been built may also affect radon levels, but this is rare.
Although quartz countertops will have less to zero radon, it does not preclude granite as a “less safe” choice in kitchen countertops. Given the radiation naturally encountered through flying, walking around a city, and living your everyday life, it is not significant enough to discourage granite in the household.
When slabs of engineered stone are cut and finished to fit a kitchen or bathroom, large quantities of silica particles are released. If workers inhale them, it can start a process leading to silicosis as well as to lung cancer and kidney disease.
At this time, one generally accepted radiation testing protocol for countertops does not exist, and neither imported nor domestic granite products require radiation testing. Radiation concentrations can only be measured using multiple portable instruments or with laboratory equipment.
Quartzite requires sealing to prevent staining the surface, while quartz needs virtually no maintenance. So if you love a plethora of choices and a reliable, consistent look to your countertops, or perhaps you're searching for a durable material that won't break the bank, quartz may be just the thing for you.
If a person sat directly on a granite countertop and did not move for an entire year, the amount of radiation they would be exposed to would equal about a quarter of a person's annual average exposure to all types of radiation, including the sun, x-rays, and airplanes.
It isn't a surprise that granite emits radiation. So do other items in our households. The amount of radiation emitted from granite can vary depending on the natural uranium and/or thorium concentration.
Quartz is one of the most durable and hygienic countertop surfaces made from a mixture of natural minerals held together using polymers and resin. As a result, quartz countertops are non-porous with nowhere for bacteria to hide.
Quartz (Engineered Stone)
It's an easy-to-clean material that is resistant to mold, mildew, and bacteria, making it a great choice for the kitchen where food is prepared. Due to the non-porous design, you don't need to worry about sealing the countertop regularly.
You could be considering finishing, maintenance, staining, durability, color, or any other of the number of aspects that come with different countertop options. But when it comes to specific interests, namely doing high level cooking in the kitchen, top chefs in the world prefer granite countertops.
Granite is porous. This means that unsealed or poorly sealed counters can absorb wine, juice or oil, producing a stain that might be impossible to remove. A poorly-sealed countertop can also harbor bacteria in its pores.
This scientific reality has caused worry for some homeowners, who wonder if granite installation can compromise their families' health and safety. But although it may sound alarming, numerous studies have shown that there is no real cause for concern. Granite is still very much a safe and popular choice for your home.
Dark and matt surfaces are good absorbers and emitters of infrared radiation. Light and shiny surfaces are poor absorbers and emitters of infrared radiation. Light and shiny surfaces are good reflectors of infrared radiation.
The radioactivity of radium then must be enormous. This substance is the most radioactive natural element, a million times more so than uranium. It is so radioactive that it gives off a pale blue glow.
Even hotter stars and other objects emit the most radiation in the blue, ultraviolet or even x-ray and gamma ray part of the spectrum. Objects like these appear blue to our eyes. Much cooler objects like planets and humans emit the most radiation in the infrared. Even cooler objects emit microwaves and radio waves.
