Granite, Radiation, & Radon

[patriotusa200]

IT SAYS ROCK NATURALLY HAS RADIATION IN THEM.

PLACE THE COUNTER ON THE GROUND FOR A ACCURATE READING.

[Huffdev]

how much was that geiger counter and where did you get that from. Whats it called?

[dahur]

@Huffdev Technically, it's not a Geiger Counter. It's a Scintillator, and a very good one. I have that model too. It's a PM1703M, and it only gets gamma, or x-ray radiation. I paid $495 for mine including shipping. I bought it from a company called Air Chek.

@greeneyedmajik

Idiot, your examples are of electromagnetic radiation not ionizing radiation. I call you and idiot and not ignorant because you are using the internet where the facts are literaly at your fingertips.

[TCSRock78]

@greeneyedmajik

Since you don't know the difference between ionizing radiation and electromagnetic radiation it is useless to debate you. Learn the difference between the two and you will understand the danger.

[Napalmdeath420]

Granite contains more poisonous substances than all other counter top material by far.

Lol, Nukular

[Napalmdeath420]

thanks for the vid! i know the dangers of granite, have you heard of the guy that worked in the nuclear power plant that set off the radiation alarms every time he went to work? this was due to a large granite rock underneath his house.... now.... his levels of radon gas were equivilent to smoking 135 packs of cigarettes a day!! a day!!!! i stay away from the shit if i can help it.....

[allgravi]

I just want to thank you (form me and my family and future family) for taking the time to test and show us how how much radiation the granite may emit. I'm just going with a high end HD formica.

[proletariatCSP]

Is the solar radiation affecting that thing since you are outside in the sunlight?

[TCSRock78]

@proletariatCSP

Not ionizing radiation, sunlight is UV radiation. Huge difference

[youngdones]

Rads or Millirads?

Do these granite slabs contain small amounts of Uranium?

[Napalmdeath420]

@youngdones Granite contains Polonium, Lead, Plutonium, Uranium, and Thalium. Other heavy metals like Arsenic, Mercury, Tungsten, Cadium and Vanadium are also present.

[TCSRock78]

@youngdones

Millrem, not millirads. Many slabs are above source grade uranium levels meaning it can be profitably turned into nuclear fuel and is supposed to be regulated by the NRC. Bg loophole here.

[memo92306]

Please check out user airchekinc video on gamma testing. This is ridiculous and immoral on how you mislead people and play on their fears. Would the US government allow granite if granite is as dangerous as you say it is?

[eenie2010]

If contain radioactive materials above certain level would be required to be possessed under radioactive materials license [it's not]. At 460 mR/hr you would have to lay your face in contact with the slab for about 325 hours to receive same skin exposure as ONE dental x-ray. If double distance from slab [say 1 cm to 2 cm] would drop exposure to 1/4 of original exposure and would take abt 1300 hours to reach exposure level from 1 dental x-ray. Don't distort risk!

[OkieCarpenter]

Wrong, even the EPA admits that some granite is above source grade for nuclear fuel, check their website on granite countertops.

The NRC has already ruled that fabricating granite above source grade requires a general nuclear license for the protection of the workers and the protection of the envirnoment.

You confused 469 mR/ with uR/hr, which rips apart your credibility. Average dental X ray is 10 mrem, the 469 uR/hr is .469 mrem, even your math is way off.

[eenie2010]

If looking at radiation hitting skin not absorbed by body - conventional dental x-ray ave abt 300 mR not 10 mrem (absorbed dose). The 300 mR is to compare apples with apples 460 uR. For source material must be > than 0.05% by of Uranium/Thorium in the granite- Do not know of any fabricators required to be licensed in US-Fabricators create dust but home owners don't -EPA states that most granites used are not typical rad contributors. TCSRock stop posting under another name to support yourself.

[OkieCarpenter]

Air Check is in the pocket of the MIA on this, that simple.

China, Canada, and the European Union have limits on granite countertops and the EPA is studying the issue this year so they can set U.S standards.

That kind of blows your arguments out of the water, doesn't it.

[memo92306]

Actually you just prove my argument. Granite is still going to be used in the US. Which blows this user claim of how dangerous granite is out of the water. Thanks a bunch.

There is always exceptions in life and that pertains to granite also. For the majority, it is even less harmful than the soil outside in your yard. So please, do not play on the fears of others by using false testing techniques.

[cornishrob123]

What about china clay .i was driving a dumper in a china clay pit for three years then got testicular cancer at 34 years never smoked was surfing for 20 hours plus a week, so fit too?

[gunplow]

what about blue granite

[OkieCarpenter]

Only one blue granite has been found of concern, comes from Brazil

[JaksProductions]

wow that is radioactive as heell

[IHAntonio]

Great video TCSRock. That shit is hot, I wouldnt want that granite in my kitchen. +400uR with a small scintillator! (that without talking of a kitchen with a lot of this graine, radon :( ) Btw, great LENi ;)

[fallingta]

Hello Liers !

Nice spreading Hoax...

You shouldn't have left schooool at 6poor boy !

boooo .... radiation ....

you should be afraid of fucking high school graduates who know more than you will ever !!

[smillar98]

Paul Harvey was right.

[smillar98]

Gamma bullshit

[LOLDISNEYLAND]

we'll no need for chemical cleaners.. after use, you countertop is sterilised.

[TCSRock78]

There are some very strange people out there that get quite upset when someone brings up radiation. They post a dozen ignorant posts that need removed, although I leave the ones up that contain vailid points for discussion. Then I get hate mail....

Seriously distrubed individuals out there who think they are experts on radiation and radon from granite countertops.

[Devilwarriar]

I don't know much about this, so correct me if I'm wrong. Would the granite having that much radiation hurt you?

[TCSRock78]

BEIR VII says a single track of ionizing radiation has the potential to cause DNA damage. The best way to answer your questions is that it is quite unwise to expose yourself to additional radiation unless there is a good reason for doing so. No use taking chances.

[educationneeded]

Anyone taking valid measurements also knows that the proximity of other slabs could contribute to the readings here. If this is gamma it may reflect radiation from the other slabs as well as the one being measured.

[TCSRock78]

You realize you are making my point, that granite puts off enough radiation to matter and that it travels a long way?

Slabs behind the granite being measured can affect the reading, but how do you explain those other videos were there was only one slab?

And we are well aware that if one is too close to some granite types, it skews the readings. We make a point of not depending on bundle measurements, but take a slab out of the bundle to accept it or reject it.

[TCSRock78]

Another bald faced lie. Read BEIR VII and quite misleading people until you do. It says that a single track of ionizing radition has the potential to cause cancer and to damage DNA.

[TCSRock78]

We have Radon measuring equipment, CRMs E-Perms, and charcol kits. We pretest granite samples prior to shipping to the researchers to save frt costs.

Save your advice and opinion for something you are knowledgeable about.

[TCSRock78]

As for my credintials, I currently sit on an ASME committee on the granite controversy and was recently asked to organize a panel discussion on this topic for the Radon scientists convention coming up in September. I also run an email group on this topic with every leading researcher that is looking into this issue, five or six PhDs at last count, a radio chemist, an uranium geologist, and two industrial hygienists one who has a PhD.

[TCSRock78]

And yes Radon is far more dangerous. But the videos don't claim to be measuring Radon. We found out last summer that the radioactivity is not a reliable tell tale for Radon, radiation can be low and the stone can still pump out a lot of Radon. There is one stone that was recorded at only 7 uR/hr, dang near background radiation but it was really putting out the Radon.

[TCSRock78]

Air line flights recieving 5,000 microrem. Another bald face ignorant lie. Several people have taken their PM 1703s on flights, you might read 30 uR/hr or 30 microrem since we are talking about gamma. This idiot wants you to belive that a flight will last 166 hours?

[TCSRock78]

And only a complete idiot would argue that any dose of radiation is "safe" when BEIR VII stated that there is no safe level of radiation. For the laypeople, the BEIR reports were written by the National Academies, a group of government funded experts that is charged with advising the U.S. government on science matters. Thousands of experts were part of BEIR VII, either working on the committees or commenting.

[neuroticnewman]

I forgot to mention, the main concern that with granite counter tops is the Radon gas that may eminate from the counter top. This is due to the fact that when the gas is inhaled, it may turn into an alpha particle through a decay process. This is what causes the issue. Alpha particles may not be efficiently expelled from the lungs and then may sit and irradiate one portion of tissue over and over and potentially increase the chance of lung cancer. Radon can't be measured using this method.

[TCSRock78]

Radiation workers are not allowed 500 millirems, that is a bald faced lie. Their doses are carefully monitored and their bosses would be looking for a job if their workers were exposed to 500 millirem on a regular basis.

[neuroticnewman]

Hmm. and a "radiation worker" - such as a dental technician, a nuclear medicine technologist, or an x-ray tech can safely receive 5,000,000 microrem in a year.  For each cross country flight individuals will receive approximately 3000 to 5000 microrem. The individuals performing the survey are right, they are not telling the whole story. I doubt if they are actually reading in units of "rem."

[TCSRock78]

crudely linear and that is all that is required of a survey instrument.

The LENi can't discriminate, but the PM 1703 is all gamma.

And that is good advice, read up before anyone believes your advice.

[TCSRock78]

neuroticnewman.

a medical radiation worker does get more exposure but they are informed of the risk and chose to accept the risk. They are also closely monitored. The deciding factor is that they are performing a much needed service that saves lives, so there is a purpose to their additional risk of cancer or DNA damages leading to birth defects.

[81dawgfr]

Actually, because they are informed individuals, workers recognize additional risks for cancer or DNA damages are so low with the low radiation levels they are exposed to that they are willing to accept the risk. It has nothing to do with "saving lives." Most individuals will not put their life on the line for a stranger even if they work in the healthcare field. :>)

[TCSRock78]

You numbers on flight radiation are wrong. .035 mrem per hour is the highest that has been recorded so a four hour flight would put you at .0140 mrem per trip, no way close to thousands of urem that you claim.

And a rem is a rad is a roentgen for the purposes of discussing gamma in general.

[ramandu]

REM is a dosage measurement. NO SURVEY METER unless it has an energy compensated probe can measure dosage. It can only measure the count rate. The fact that they aren't discerning between alpha, beta, and gamma is also an issue.

Read up before you believe these people who buy a geiger counter online and suddenly are experts on radiological measurement.

[TCSRock78]

We have here a couple of ignorant "experts" pontificating. First off, this video is directed at laypeople, not experts that know the jargon. Had you understood this you would remember the saying "a rem is a rad is a roentgen." because we are mainly concerned about Gamma radiation.

[TCSRock78]

The public doesn't usually know what a roetgen is, so rem is used, and it is rem, not REM. The R is capitalized when using roetgens as in uR/hr. But regardless, the LENi pro has a dual scale, cpm and roentgen, which only a hair splitting fool would argue with. As to the accuracy, the meters will over respond at some levels and types of radiation and it will underrespond on others.

[TCSRock78]

Not so, there have been no published studies that found less cancer in higher radiation areas of our world. A few attempted to draw that conclusion, but BEIR IV looked at all of them and rejected their premises. The scientific consensus is still that there are no safe levels of radiation.

[vmelkon]

That kind of radioactivity is very low. 4560 cpm is noting.

[TCSRock78]

That comment is either ignorant or a bald faced lie. Background radiation measured with the same Geiger counter is 57 times less than the hot spot on that granite slab. 80 cpm is the average background in Oklahoma.

[xxCCBBxx]

i personally think all granite owners are in denial. i think the stuff is beautiful but is it worth the potential risk??

[souldagger14]

hmm maybe you should get away from it...

[mightymaster8]

where do I get one of those testers

[TCSRock78]

That meter is sold out for the less expensive ones ($382.00)  but the yellow meter is still available.

We are putting together a bulk order soon. $350 per meter if you want one.

[TCSRock78]

Foul mouth Peter,

that is the idea, this stuff is way too dangerous to install inside a home.

Do you eat with that mouth or yours? Now that is nasty.

[peter1114222]

any way you turn it i wouldn't want this crap in my kitchen so screw all you granite merchants go fuck yourselves

[f1biv]

Thanks, it's too space ...

if you want to search easyler the top with the pm1703m,

you can make a new point of CALibration.

regards.

[TCSRock78]

Well, I didn't get to review this before it was published, & there are several mistakes I made. First time I've done this, wasn't prepared. This is real life, warts and all. Two mistakes I found: The Geiger counter on X100 was actually showing 10 millirems, not 1 rem, stupid mistake on my part. The second mistake was when I was pointing out the data log info. I said 456 cpm when I should have said 4560 cpm. I'll review it again tomorrow night to see if there are any more errors.
