User questions & answers

Question:	Will this measure the radiation level present in gemstones
Answer:	Not all gemstones emit high enough levels of radiation that can be discerned above ambient levels of radiation and it depends on the actual level of radiation the stone emits. Stones that have been exposed to radiation to change their color will probably not register. I have some uranium marbles that are not detected by this counter. My wife was subjected to a PET scan, last year and read 790 CPM from a distance of 6 feet.
Question:	can I use this to measure Fukushima radiation in seafood
Answer:	I've read articles regarding radiation in seafood indicating the levels you read may be may be misleading. The GMC-300 will measure this radiation. Here in Northern Indiana the ambient level is normally 30 - 40 CPM. As shown in the video, levels in sea life can be higher. http://www.opb.org/news/article/scientists-say-stop-worrying-about-fukushima-radio/ Rick
Question:	I'm a novice wanting to check for radiation levels. Is this device easy to understand? What can I use this for to measure for radiation
Answer:	The GMC-300 is easy to use and low priced as an entry level radiation detector. I use mine to monitor background levels of radiation as I have yet to find an highly active source. Here in central BC, Canada I get 14 to 22 cpm, with a high of 30 cpm. It appears to decrease after a rain fall. The only thing missing with the GMC-300 is a radiation standard but I can understand why.
Question:	Would this device be able to tell if there was leftover radiation from a nuclear blast or contamination? Or radiation from dirty bombs
Answer:	I’m a radiation protection technician. If this device works the way that it says it does then it would still not detect alpha or neutron radiation. If you suspect something making into your food or water then I would be most concerned with Alpha particles and this doesn’t measure those. You shouldn’t have to worry about neutron radiation though and unless you’re using it to measure something you’re ingesting then alpha radiation really isn’t an issue. Geiger- Mueller counter can detect beta and gamma/X-ray radiation. I’d be interested to see how they measure Beta since you really need a gas chamber to measure it accurately. I would be most worried about beta and gamma radiation if you’re talking about an area that may have had nuclear weapons detonates years ago. This claims it can measure for those. If it can it would be a good device to determine if your surroundings are still giving off radiation.

User questions & answers

Question:	Why do they show it in use near hv transformers? does it also detect em emissions in that range
Answer:	No, you would need and EMF (electromagnetic field) detector for that: https://www.amazon.com/Advanced-Electro-Magnetic-Detector-Monitor/dp/B007ZBETWC/ EM emissions are non-ionizing radiation, which means the particles do not have enough charge to cause damage to tissue. Geiger counters detect ionizing radiation, the dangerous kind: Alpha, Beta, Gamma, X-ray, etc. Illustration: https://quartarad.com/wp-content/uploads/2018/10/ionizing-radiation.jpg https://quartarad.com/wp-content/uploads/2018/05/types-of-radiation.gif I hope this clarifies matters a bit!
Question:	Is this detector EMP proof
Answer:	As a former designer of electronic circuits, I can opine with 99% certainty that it is NOT EMP proof. I say that because the outside is plastic (a non-shielding material), and the LCD screen also would not block radiation. I think to add EMP protection would raise the cost considerably! FYI, I store my detector, when not in use, inside a metal container (with other electronics) because of its vulnerability to EMPs.
Question:	What is the difference between this model and the RD1503+ without dosimeter model
Answer:	This model does have the dosimeter function (see "DOSE" on the LCD screen), which means that it can switch between immediate radiation levels ("NOW") and accumulated dosage over time ("DOSE").Very useful when working in environments with even slightly raised radiation levels (warehouses, junk yards, granite canyons, treatment plants, etc.)
Question:	Can it detect all of "alpha", "beta", and "gamma
Answer:	It detects beta, gamma and X-rays. No Alpha because it is redundant and unnecessary. Alpha particles are relatively "large" and won't pass even through a sheet of paper or a layer of skin, let alone plastic casing of a detector. It also emits only a few inches from source. Illustration: http://images.slideplayer.com/32/9849845/slides/slide_10.jpg One would need a special "pancake" appliance to detect it, and those cost up from $ 500. In my opinion, those are only useful for conducting experiments in a lab environment, or under some very specific circumstances. Another reason for not detecting Alpha: nearly every radioactive isotope that emits Alpha will also emit a lot more beta and/or gamma (usually both), which will be detected by the sensor. Hope this clarifies matter a bit.

What is nuclear radiation?

As radioactive material decays, the energy released (Nuclear Radiation) into the environment. It will harm a body that is exposed to it. It can directly kill cells, or it can cause mutations to DNA. If those mutations are not repaired, the cell may turn cancerous.

The common source of nuclear radiation can be: Leaked dust of nuclear power plan,nuclear weapon explosion,X-ray machines,,nuclear waste materials ,Iodine 131 medical treatment patient or animal,contaminated fruit, seafood,,Ionizing smoke detector etc.

Monitoring radiation from a I-131 treatment patient

Patients who need to know the radiation level after radioactive iodine treatment are advised to carry a GQ GMC-320 Plus. This will let patients keep a safe distance to other people. The patients may also need to know how long they can travel, Radiation detection devices used at airports and federal buildings may be sensitive to the radiation levels present in patients up to three months following treatment with I-131.

Fruit radiation detecting

To avoid contaminated import fruit, the GQ GMC-320 will let you know if the fruit has been contaminated.

Seafood testing

Seafood always be the first victim of the nuclear power plant disaster. Always do the radiation testing on all sea food from the disaster area. So that to avoid contaminated sea food.

User questions & answers

Question:	How does the dosimeter work? Does it have to be turned on to track your dosage? Do you have to carry it at all times for a time period, like a week
Answer:	Great question! Any kind of nuclear dosimeters, including SOEKS 112, have to be turned ON and on the person/in the environment in order to record the radiation dosage. It has to be carried around to accumulate the dose. SOEKS 112 can show real time radiation or the accumulated dose with a single press of a button.
Question:	At what number on the display should I turn and run? Is this the same unit model sold by "Mirasafety
Answer:	You should see numbers below 0.40 uSv/h in the USA for natural radiation background. It doesn't mean you have to run yet but definitely something to investigate as to why the numbers are higher than naturally should be. If you see numbers higher than 1 uSv/h - it's a good idea to increase your pace with the toes pointing away from the object or the area with high radiation. SOEKS is the original manufacturer of this portable Geiger counter, including the ones that are sold by Mira safety. It's always better to get our detectors directly from the manufacturer as we guarantee that they are stored properly and up to date with the latest updates. Regards, Andrew from SOEKS USA
Question:	Will it or any software track history on iOS device
Answer:	No, this is a standalone Geiger counter/Dosimeter that makes and keeps all the measurements on the meter itself.
Question:	Why it's so slow? You can die before you see real radiation numbers
Answer:	When High radiation is detected, you’ll know it right away - there will be a spike in the readings, the audio clicks will become very frequent, and the visual indicator (LED) will blink rapidly. No way to miss that! For subtle changes in the radiation background the maximum time for the most accurate readings takes only 2 minutes, usually less. 120 seconds is not enough time to get a lethal dose even during the Chernobyl disaster. And the best part, that this small Geiger counter (dosimeter) reads up to 999 mSv (999 Sv), while the Geiger counters initially used in Chernobyl only read up to 34 mSv, hence the delay for the alarm and the emergency response.

Question:	Are these ansi n323 certified first accuracy
Answer:	This unit is calibrated in GQ Electronics Lab, not others. It is a general-purpose Geiger Counter.
Question:	will it detect radiation in water
Answer:	If your looking to "see" the radon particles in the water probably won't notice much difference between the water and background radiation unless it was a significant amount... I would recommend putting the water in a glass or beaker and set the monitor on top to make readings... I may try that myself and see what results are if any..
Question:	Does this unit detect and mesure the radiation from a smoke detector
Answer:	The GM tube of the GMC-600 Plus is a pancake one with a thin Mica Window. This allows also Alpha radiation to enter the GM tube and to detect it. A smoke detector can work with Am-241 isotopes and uses Alpha radiation for smoke detection. But all detetctors I know are very well shielded, so no Alpha radiation weill leave the smoke detector. Therefore, no external radiation detector will be able to detect the internal Alpha radiation of Am-241! Regards Uwe Z.

User questions & answers

Question:	Does it have a seting in measurment from usv to u,milli rems hr
Answer:	No
Question:	How do I know if this device will tell me if there is harmful amounts of radiation in the environment after a Nuclear bomb has dropped
Answer:	You need a radiation check source. Intact Smoke detectors don’t work well because it is a clean alpha particle source and is well shielded. You can get a slight reading above background if you place the counter back right on opened smoke detector. DO NOT take the detector apart, anyone asking this question does not know enough to do this safely! If you can find an old thorium lantern mantle, they work very well. Many new mantles do not use thorium anymore but the thorium mantles work a lot better so they are I demand. There are many sellers on eBay selling thorium mantles and as any Geiger counter can easily detect then, is hard to lie about this for long. 1930’s orange fiesta ware also works well if you can find sone (it used a uranium compound for color). You may be able to detect the radioactive material in an intact But you can also just buy a source. These can include uranium ore or Monazite sand. You can also find old radium watch dial hands for sale ( do not touch these, keep them in the bag). And there are always sealed samples sold for theses uses though they are often very expensive. You can find them on amazon occasionally, but more often on by eBay, and always at places like United Nuclear. I would recommend the thorium mantle route. If I can post a picture I will, but a piece of mantle in a plastic bag gives me 1.24uSv/hr in a background of 0.12uSv/hr. Using a smoke detector as source 0.19uSv/hr. Big difference.
Question:	Does this product work
Answer:	this geiger counter works very good . it is extremely sensitive. highly recommended
Question:	Two questions: 1. Does this include usable instructions? 2. Does this unit require calibration
Answer:	The instructions, as well as text on the screen of the unit, are in (what I suspect is) Chinese. Pretty far from helpful. However, operation of the unit is fairly intuitive, and it doesn't appear to need calibration.

User questions & answers

Question:	Will this product detect radiation from food such as bananas
Answer:	I haven't tried it yet. Nor have I tried Brazil nuts. But the device was very accurate when I passed over the hands of a watch painted with radium 226. My confidence in this device is very high. I would buy it again without hesitation.
Question:	Can this read in pCi/L
Answer:	It doesn't have to be a radon detector. The device appears to display only counts per minute and can convert radiation units into a "human effective dose" in mR or uS. However, typically it's software that performs unit conversions- so YOU "could" be the computer to convert cpm to pCi/L using using this detector- IF you have the prep supplies & a source that is the same radiation type (such as alpha) and the same dimensions (L-W-H) as what you would like to measure (if you wish to quantify pCi per air volume, the size of the source should match that of the air filter used to collect the sample- see more below). The known activity of your source can be in pCi or any other unit that can be converted to pCi, such as dpm). Measure the activity of the source using your GQ 600-GC (in cpm)... Divide the known activity of the source by the instrument measurement in cpm (you might improve your measurement by repeating this several times and taking the average after removing any statistical outliers). This gives you an efficiency for the type of activity you are measuring. The efficiency will be different for alpha than for beta & again differs for gamma.. etc so your known source must be the same radiation type even to estimate the activity. Here is an example of air sample radiation measurement using this device: The measured background level in the location where you plan to perform sample measurement is 50 cpm. If you are looking for alpha contamination, your source could be a circular shaped lamp mantle, 37 mm in diameter, quantified to contain a known quantity of 0.027 uCi of thorium (27000 pCi) at the time of measurement- this does not mean that all lamp mantles have this activity- you'd have to purchase or otherwise obtain a source with a known concentration at the time of measurement to perform any quantitative work with any detector. If the source measurement is 5050 cpm, the instrument's alpha efficiency is calculated as 27000/(5050-50 bkg) = 5.4 (take the average of several repeated measurements for bkg & source after removing statistical outliers for the most accurate efficiency). To collect an air sample, you could use a 37mm filter with a sample pump rate is 1.5 L/minute. If you performed the sampling for exactly 12 hours, your sample volume = 1.5L/m X 60m/1hr X 12hr = 1080 liters per sample You would then measure the background again (10 cpm again we hope) & then take a reading of your filter (again, an average of repeated measurements, removing statistical outliers, is a better indicator than a single measurement). If the filter activity is 60 cpm, your air activity =(60-50bkg cpm) X 5.4 eff= 54 pCi per filter divided by 1080 L volume =0.05 pCi/L . This is an example of this same measurement using a liquid sample and assuming the same measurements: If you have a 2 liter sample, you'd dry the sample under a heat lamp or on a hotplate- directly onto a 37mm planchette (this would be a slow process unless you used acid & other chemicals to keep radioactive material in solution so you could perform some of the volume reduction using a larger vessel first. Also, if there are solids on your planchette, your measurement will not be correct since solids can shield alpha activity and some beta). Assuming no solids, measure the planchette exactly as you did the filter above. If the planchette activity is (60 -50 bkg cpm) X 5.4 eff = 0.54 pCi / 2 liters = 0.27 pCi per liter. If you don't happen to own an air pump, standardized radioactive source, drying apparatus, & beakers, filters, etc. (even if you purchase a GQ 600-GC), you'd need to hire professionals to perform sampling & analytical measurement. In all seriousness, this is an interesting & cool toy- not relevant to exposure monitoring or quantifying material.
Question:	If it has a plastic enclosure, how can it detect Alpha radiation
Answer:	The picture is wrong. Check out the pictures here - https://www.amazon.com/GQ-GMC-600-Counter-Detector-Dosimeter/dp/B077V7QSHP/ It has a metal mesh for Alpha detection.
Question:	If it doesn't distinguish between alpha, beta & gamma rays, when to be worried, since alpha, beta can be blocked more easily than gamma rays
Answer:	The Alpha can be easily blocked by a sheet of paper. The Beta can be blocked by a block of aluminum.
