Is this something i can use in a supermarket to check food for radiation? i don't trust things coming from the pacific ocean because of fukushima.

Testing food in general is one of the most common questions we receive and also happens to be one of the most difficult ones to answer. In short: - Can food be tested with a hand-held Geiger Counter? Yes. - Will it detect elevated levels of radioactive materials, if present? Yes. - Is it absolutely safe to eat your fish after you scanned it and the result was negative? No, not necessarily. This is not a sensitivity issue, but is simply because radiation emitted from a tiny contaminant will be masked by the natural background radiation that's all around us. Technically speaking, everything is radioactive, even we are. So it would be like looking for a specific water drop in a pond. If the natural background radiation around you is .10 uSv/h and contaminant in the fish emits .02 uSv/h, then geiger counter will naturally continue showing .10, because that's how many radiation particles it is detecting in your immediate vicinity. This means that no matter how sensitive, expensive or calibrated your equipment is, the only way to be absolutely sure that food is safe would be to test it in a lab, where a piece of produce is placed inside a special lead capsule that isolates it completely from any background radiation. There is a lengthy scientific procedure of setting up such tests. Many manufacturers will claim that their detectors will works just as well, but as you can clearly tell, that is a marketing scheme. The only sure way of accurately testing food for radiation is in a lab. Period. Having said that, there are still ways to considerably improve you chances of detecting contamination. Here are some practical tips in getting the most out of your RADEX geiger counter. Whenever anything is measured for radiation, the mass / size of the object being scanned matters. Don't try to detect radiation in a single berry, a mushroom or a cup of water. Unless these are highly contaminated, there would be few particle streams emanating from a smaller volume hence the chances of detection are that much lower. Instead, try scanning an entire basket-full of produce, or a tank of water - the number of particle sources would be that much greater and easier to detect. If it's fish your are measuring, try to have as much of that tuna as possible. Turn the unit on and place it right next to the object (you can use a simple plastic bag to protect the unit - that won't effect sensitivity) for about 40 seconds. Then move a few inches to the side, and so on: continue displacing the detector by the distance of its width every minute or so, moving alongside of the object being scanned. So basically from head to tail. That would give you the highest chances of detection. However, please keep in mind, that even if after scanning it this way, there is still a chance that it may contain radioactive elements that are above the permissible levels for digestion. This is why we NEVER recommend to use Geiger counters for food testing unless in dire situations. We hope this clarifies matter a bit.

Does it use a cylindrical GM or a PANCAKE GM tube? What is the best measure of the tube life that you can give parameters to? Thanks!

Cylindrical low voltage SBM20-1 tube. Only does Beta and Gamma. Its does work well. A nuclear plant recently had a leak about 245 miles north of me, and it went bats as I was downwind and it showed elevated radiation at 6 times my normal background for 45 seconds so I know I caught a wisp of it. This is not professional lab equipment, but is good value for what I paid for it. The battery life is awesome too with LSD rechargeable NiMH AAA batteries. I run it 24/7. At this price, I do not really care about tube life.Just do not expect professional grade results from it, but it is good enough and a good value for the money.

what are the minimum sensitivities for beta/gamma? IE: how many KeV in those bands?

Gamma: 0.1 - 1.25 MeVBeta: 0.25 - 3.5 MeV

where is this product poduced and manufactured

According to the radiation certificate that is included in the package, the RD1503+ monitor is manufactured by the QUARTA-RAD Ltd company in Moscow, Russia. http://quarta-rad.ru

This instrument is very accurate.

When one has to rely upon an instrument in terms of H&S issues, it had better be good. Whilst this instrument isn't rated as a top professional Geiger counter, it is accurate enough to be used as a warning indicator, in terms of bringing in a professional team of experts. Some may consider it a little greedy on batteries, but that should be of no consequence considering its designers are up against the laws of physics. Geiger counters do tend to be energy greedy. I am most satisfied with this instrument, as it is very portable and may be inserted into quite a small space. I'd stake my reputation on it, if that's anything to go by. This is no cheap toy, it is the real thing.

Genuine

A good product , is doing the job was made for . You can check on a smoke detector in your house wich have a soft radioactive part . I check to mine and i got a value of 0.30 - 0.50 to smoke detector . Is an indispensable item to add your surviving bag . Highly reccomand...

This for third party in the nuclear industry

This I can tell you is better than many will till tell you if you are a third party qualifies to carry Type A packing group 3, 2 or 1 packages. This unit is spurious to say the least accuracy but instantly and also over time because it rests itself, it does show what levels of radiation you are involved in. All in all for the price, top piece of kit. (the readings I get from this true with units that scan my vehicle cab before journey and scan the same)

Finally the Geigercounterhell is over and I have a cheap device that is really reliable and readable.Plus it is so small you can just take it along.

Sent radex 1503 not 1503+

Sent me a radex 1503 not as advertised, also the tube had small hole in so readings don't seem accurate, fast shipping but as an engineer I have repaired the device myself but for the price you should advertise correctly. I have had to buy new Geiger tube to repair it. Also to top it off the menu is all in French and the manual is in French. I had to download the PDF in English but it is definitely the radex 1503 and does not have vibrate function. I will buy another type when I get my next wage. Not happy with the service though. I would have returned but can't be bothered with all the fuss. Cheaper to buy an extra Geiger tube that is not faulty.

Best Geiger Counter

I'm not an expert but this is really easy to use and it seems very accurate. Definitely recommended if you want to check things around.

It was love at first count :)

I have 6 Geiger counter radex rd1008, gamma scout, radex one, gmc 300e , and a Chinese one and now this little guy. Pros: Fast, accurate, better software, battery lasts, backlighting, small. Cons: no USB port, only one tube, no hand strap, sensitive to humidity. Great for anyone that wants to know what is safe to eat or if the area they are in is safe. Honestly I wish I would’ve bought this from the beginning and not wasted my money on expensive ones, I compared the readings to the gamma scout and rd1008 and they were spot on and a lot faster ! It’s quite rare when I say I would buy something again.
