I'm late, but I finally got an Inspector USB! It's easy to use for how complex it is! This is an amazing Geiger counter! I have a lot of radioactive sources, and some of my sources overflow the detector, but the fold-back effect will happen at high levels for any Geiger counter. However, it has anti-jamming! The Observer software is really nice, too! I'm so glad I finally got one! I'd recommend it! Thank you very much, Tom!

Thank you for your great review! This unit seems to be very useful, mabe I will buy it in future to replace my Gamma Scout. Thanks for testing it

Hello Tom.I have a question for you ..How do you determine how much radiation is to much for the humane body ? Like standing out side with your inspector usb unit and hold it in the air what would be to much ?? I know you have to subtract back ground from this reading correct?? Do you have to set the meter to pick up certain things or can you just leave it on default and it will pick anything up under default mode..I am trying to figure out in cpm or millarogens what is to much for the body .thanks for your time Joe..

how will i perform to get background of materials for example scrap metals? using Radiation Alert Inspector

Hi Tom, just wanted to say absolutely top videos! :-) I've been working my way through your video's for a while and learning alot of new stuff. Had to subscribe! Definitely one of my favourite channels do thanks for the awesome videos, useful information and the funny content ha :-) After your review I bought the Inspector USB (you should mention that to S.E international haha). Extremely happy with it!! and I'm very tempted by the EXP, one question... Is there a difference in the EXP and the EXP plus? I've seen them marked differently. Keep up the videos :-) Jason from England

558JayLay434 Hello, I'm glad you like the videos. I haven't produced any the last month or so but I'm working on some more. The plus had a few more features than the regular EXP, but you shouldn't be seeing the regular EXP anymore. The latest EXP should be the equivalent of the inspector USB but with an external probe. I normally buy my Geiger counters from Geigercounters.com, but they show their exp as the old one and not the current model which is on SE international's website. You may contact Geiger counters.com before buying one, unless you go somewhere else. Is any particular reason that you want the probe? that's the only difference between the inspector in the EXP model. EXP = EXternal Probe. On a side note, keep in mind that if you use the alarm function your battery will run out really fast. Just an FYI.

Thanks for the reply Tom. That's good to here i'll look forward to seeing them! :-) Thanks for the information regarding the EXP, i had a feeling that might be the case. I will check out the link, i think i have had a brief look on there before, there prices seem very good (although anything of value coming to the UK tends to get heavy customs fines). To be honest i just like the EXP for its advantages, i have a few fairly "hot" sources that are nice to keep at arms length ha. But to be honest i just like the EXP and being a geiger counter addict it would be nice to add to the collection :-) The Inspector USB is fantastic though, it goes everywhere with me! im finding things in the house radioactive that had never been noticed by the lower end counters :-) thanks for the advise too. much appreciated.

Hi, what it better, Mazur PRM 9000 or Inspector model? Some price.

I just got an Inspector USB today! When you switch it to Total/Timer, push the "Set" button. Then, use the "+" and "-" buttons to set a preferred time. Then, push "Set" to start counting. 1 minute is the shortest, and 24 hours is the longest. You can switch to count or dose while it is on the timer. It will show an hourglass icon, meaning it's counting. After the timer has ended, it will beep 3 times. The number shown is the counts or dose/time. You can use the "Set" button again to start counting again, or to disable the timer by switching back to Total/Timer mode. Turning it off will also work. I hope this helps, even though I'm a little late!

I _think_ that starts a countdown to calibrating the unit, but only if it's switched to the "mR/hr μSv/hr" mode. Be careful! You don't want to do this if you don't know how, or if you do, but lack a calibrated Cs-137 source or a pulser. I did it to mine, thinking nothing was going to happen, but it beeped. Luckily, I think it was switched to the "CPM CPS" mode, since I don't use dose mode that often. So, I turned it off. Luckily, nothing bad happened, but it could have!

I'm sorry but I just can't wrap my mind around of what "calibration" means; is it important for all Geiger Counters?

@Anti-proton

9 жыл бұрын

Calibration means to determine what dose of radiation a user is exposed to at a given count rate. For example, your car is calibrated so that a certain wheel speed reads as a certain velocity on your speedometer. You could drive the car beside another car which was already known to be moving at 100 MPH and then adjust your speedometer to match that. That would be calibration. Now, when a Geiger counter is exposed to a specific amount of a radionuclide, perhaps Cs137 as an example, at a given distance, you can mathematically calculate the dose rate you are exposed to. For example, Cs137 of some given quantity and distance might expose to detector to 1 μSv/hr. You could read the detector and see what it said, perhaps 100 CPM. Do this again at 10 μSv/hr and see what you get, perhaps 1000 CPM. (10 μSv/hr - 1 μSv/hr)/(100CPM - 10CPM) = 9μSv/hr / 90CPM = 9/90 = 1/10 μSv/hr / CPM So, our hypothetical Geiger counter gets 0.1 μSv/hr per every 1 CPM. We now know that: Reading Dose rate 10 CPM 1 μSv/hr 500 CPM 50 μSv/hr 1,000,000 CPM 100,000 μSv/hr That is calibration. You might notice the flaw... it only makes any since if: 1. The radio nuclide being measured is the same as the radio nuclide used in calibration. 2. The geometry and conditions need to be about the same. 3. The background must be discounted. Personally, I do not worry about calibration for dose rates. I use it to ensure my unit is always accurate. As a result of being calibrated, the unit is also checked against a known source. This is a good way to detect bugs and flaws with the unit.

Does anyone know if this unit is sensitive to neutrons?

No. You need a detector that uses a Helium-3 proportional tube or a Boron Trifluoride (BF3) proportional tube. These tubes can be attached to certain Geiger counters, as long as the voltage is properly set, like a Ludlum. Or a Lithium Iodide detector if you are using a scintillation counter.

Thanks Tom your the best. Your the reason I got into collecting uranium. Hey by the way I have a piece of uraninite I would love to gift to you if you would do a video doing some sintilation scans on it?

Hy antiprotons! Nice Video! I get an Inspector for testing issues. I want to compare it to RD1008 from QuartaRad (Radex). I noticed, that the Inspector is really sensitive, much more than RD1008 which already is quite sensitive. But something is really special and I do not understand: when i measure a uranium pottery with RD1008 it displays 60uSv/h and also with all other counters I have...all have different tubes and are more or less sensitive....but all are accurate and therefore display the same value. The Inspector shows with the same pottery 280uSv/h which is far too much?! Any Idea why this could be? Yes, the Inspector is very very sensitive...but at the end it should display the same value in uSv/h like the others...otherwise I don't know if any of this counters displays the truth...?

@KarbineKyle

5 жыл бұрын

You should measure in CPM or CPS rather than a dose rate, like uSv/hr or mR/hr. Dose units will only be accurate if it's calibrated to a specific isotope. Most Geiger counters are calibrated with Cesium-137. Some are calibrated with Cobalt-60. If it only measures in dose, then just use that, since there's no CPM or CPS option. However, different isotopes will give different readings, even if they have the same specific activity. But it has to do with a number of other things: Geometry of the tube, thickness, material used in the tube, voltage, anode resistance, distance, dead time, sensitivity, and conversion ratios. The Inspector uses an LND 7317 tube with a very large and thin mica window, which allows detection of alpha, and a broader range of lower energy beta and gamma/X-Ray energies too. The Radex 1008 uses a Beta-2 and Beta-2M tube. This has two tubes, and this means it can distinguish between beta and gamma radiation. I don't have this counter, but I do have the Beta-2 tube with an Eberline RM-20, and also an Inspector USB. They are similar in geometry and size, but the thickness of the window is thinner for the LND 7317. Unshielded, the Beta-2 can detect alpha particles, but less efficiently than the LND 7317. They also have different dead times and operating voltages. I couldn't find a conversion ratio for the Beta-2 or Beta-2M tube. Anyway, the larger the tube, the more the counts it gathers. The thinner the tube, the more sensitive it will be. I would recommend looking up "DIYGeigerCounter". Look for "GM Tube Info" under "Technical". DIYGeiger has a list of many tubes and their specifications. It's complicated, but it gets easier to understand. Hopefully, this helps!

We have about 70+ children and 100's of adults being diagnosed with cancer since about 2010. the area is a large area but rural. one of the childhood cancer types is called rhabdomyosarcoma and it is very rare. we have about 6 of those now, they started mid last yr. Anyway in researching other clusters in the US, the implicated cause was ionizing radiation or combination of tungsten, cobalt, and nickel. we found info on line that a power plant 50 miles north of us had spills in 2003, 2005, 2009, and an Unknown SIZE release in 2011. it seems like a long way off but there is a Aquifer Recharge area close to the power plant that feeds groundwater into the Aquifer system that most of the childrens water source comes from. we also found that the alpha levels for radium 226 increased in municipal supplies. but radium was all that was tested. we watched a video on line about a guy in texas who discovered radioactive hot water heaters and pipes because of 3 -4 years of exposure of radium in their water. local ppl are showing high on metal testing for cesium and strontium but not tested for radioactive. Since testing is so very expensive and we don't know exactly what we have, we thought about using the Geiger counter to find the hot water heaters and water that had the highest Totals, then send that specimen to the lab for analyzing. from there maybe we can identify a single isotope to test at all the other homes... thoughts??

Hello, (sorry about your email. I get billions of them and they get lost) The model 12 is actually a general purpose meter, not a Geiger counter. It can be connected to many types of detectors, such as a geiger muller tube (e.g. the model 44-9), a scintillation probe (like my 44-2 NaI(Tl)), and I think it can accommodate a neutron detector too. The model 12 is useful for scintillators, while the model 3 is best for geiger muller tubes. The 12 has additional features which benefit scintillators. As for the Inspectors, the EXP is the EXternal Probe model and the USB is the normal model. You can now get an EXP which is also a USB. I'd ask before buying (though I recommend the normal USB). I am unsure of the extra ruggedized features of the xtream unit, but you can buy the rubber cover, the xtream boot, for any of the Inspectors. I would not buy an inspector without the rubber boot. All of the inspectors have the same Geiger Muller tube: The LND7317 (www.lndinc.com/products/17/) They have the exact same detection specifications (as of last time I checked, a few months ago). These are comparible to the LND 44-9 pancake probe (ludlums.com/component/virtuemart/radiation-detector-185-detail?activetab=introduction) The big question is what are you trying to accomplish. If you detect radiaton with these units, you will not know if it came from Fukushima.

For around $270 you can get a pancake probe add-on to make the CDV700 as sensitive as the Inspector. The issue is that CDV700's, while cheap and robust, are also old and need repair. You would need some basic electronics skills.
