Does it work? How do you know? I want to check some granite for radioactivity before I install it as a countertop.

Wrong type of device for what you want to test. This is a single use exposure dosimeter. You are looking for giger counter.

My RAD sticker has been inserted inside clear plastic my work ID badge sleeve. To date, it has never activated. My current (undisclosed) employment location is within the Washington DC beltway. I hope I never need it.

It turns darker as it's exposed to radiation. If you are suddenly exposed to a high dose it instantly turns dark but it also slowly darkens as you are exposed to low doses. Like if you are on a plane or go through those body scanning things. I think it's probably best for a catastrophic situation where you might be exposed to radiation and need to know to get to a dr.

RAD sticker is a cheap and accumulative radiation hazard indicator. It is not design to measure single radiating application with high accuracy. I just stick on my ID card, check for any color change periodically. Hope I never see it changes. "Discrete, compact and cheap" are the key word for RADsticker.

The radioactivity would need to be measured over months. The dangerous component is Radon gas. In the form of a countertop, the exposure levels of even a relatively highly radioactive sample would be smaller over a decade than a single aircraft flight exposes you to. If you are worried about radon in general get a long term radon test kit from Kansas State University ($25, includes testing afterward) and use it in your house. (search for Radon test kit, and look for sosradon.org )Even a $200 detector wouldn't pick up the radon as it is an alpha emitter, and only dangerous because it's a gas (you breath it in) as it can't even penetrate unbroken skin.

Sorry. I can't say. I bought it specifically to seal granite, and it did a great job. Hope someone has an answer for you.

No it is not a spectrophotometer . It is a crudely simple radiation counter. It is mainly gamma rays sensitive. The most interesting usage I had from it was from taking it up in a commercial jet on a holiday and watching the radiation levels soar to about 20 times what it was in my kitchen. (This is well-known but still interesting to see oneself.) I have also detected beaches that were radioactive with natural thorium but it has to be laid on the sand to work. It's a bit crude and it is worth knowing the basics of radiation counting before you use it, for example what a sievert and or micro-sievert is.

I'm not sure why the instructions say no because I've been using it on my granite counters forever....

I would guess it depends on the countertopI installed a granite countertop with an undermount sink

We returned the product. We found out it was for unpolished granite. our counters are polished (shiny)

I use it on everything including granite. They do have a special one for granite called "take it got granite".

I have used it on the underside of granite, but it shortly failed. Restuck it with hot melt. Been stuck now for a year.

I used it on a cream granite and left a small residue. The residue is now gone so I don't think you should worry about it but just in case test it on an area where most people can't see. My installer left behind the pieces where the apron sink was to be installed so I test it there first to make sure no issues. If you have any un used pieces test it there first if not, just go where you got the stone and they typically have broken pieces they don't mind giving away. Hope all goes great!

I think it would. I think I would call a granite counter expert with the ingredients as Melanie suggests, however.

we used it on a standard sink and formica counter top but it would prob'ly be fine on a granite counter, too.

It does not look like granite...However, it looks way better than dated counter tops. Installation is key. It is time consuming. It can't hurt because you can remove it and your counter tops are just the way they were when you started. Good luck!

Hello, I assume yes because it does indicate several materials it can be used for but we use it for our kitchen granite counter tops and it seems to work good. I would suggest to contact the company to make sure it works on marble as well before you make a purchase. Good luck

I did my countertops a few months ago, and so far so good. If you leave things sitting on the counter for long periods, it leaves tiny indentions but they disappear over time. You do get very tiny scratches from cleaning but can not tell unless you are inches from the countertop. You must work quickly with this stuff because it does harden fast, but the end result looks nice as everyone thinks I have new granite countertops now.

I have granite and no issues. I had a plumber install, not corking on granite.

Good Question,I would suggest that you contact the Granite Digital Tec Line, at 510-471-6442 or their 888-819-2190 number, for a recommendation.They are very good to work with. Sorry I couldn't give you a better answer. Keep in mind that it works best as a battery maintainer.

We installed it to newly installed granite tops. Plumbers remarked about the weight so there several plumbers and the stone mason to help insure it was installed correctly.No issues but careful planning.
