RADEX ONE Personal RAD Safety"Outdoor Edition" High Sensitivity Compact Personal Dosimeter, Geiger Counter, Nuclear Radiation Detector w/Software

Never owned a Geiger counter before, so here are my dilettante impressions.A very interesting device!First and foremost: do yourself a favor and download the PC software from the company website to make things easier.The software makes it easier to make sense of the settings and the data.Otherwise, simply turn it on and let it work. No need to calibrate or any kind of setup.Straight out of the box: put in a battery and push a button.Done.The radiation measurements are nearly instantaneous, but wait for about a minute to get the most accurate ones.The measurements in my case tend to jump around between 0.13 and 0.18, which is normal (as long as lower than 0.30).There is a little radiation symbol that blinks on the screen every time a radiation particle is detected, gives a bit a of a good old analog feeling.I placed the device on a granite countertop in my friend's kitchen and it worked! I got a much higher measurements than I normally see.Note: do not expect these devices to work on microwaves, radon gas or Wi-Fi - that's a different type of radiation. Need special detectors for that.Nor sure what the difference is between this model and the white one they have. I have not found anything so far. Maybe a software thing? Anyways.I like that it is easy to use, compact, clear readings and not too expensive for my first geiger.The little manual gives a good reference of safe levels vs dangerous levels.Audio beep can be turned off and there is also a vibration mode, like on a cell phone.Room for improvement: no internal memory.Readings are either shown on the device immediately (like a thermometer) or can be fed live via cable to the laptop to be shown and recorded in the software.Otherwise, a solid recommendation. If you have a question - email the company, they got back to me in less than an hour!

This dosimeter is pretty handy. I purchased it to keep track of how much radiological dose I was getting at work. While this device is no replacement for an TLD/OSD or film badge, it is nice to have one of these on hand to get a rough estimate of how much radiological dose you are exposed to. You can stick this thing in your pocket (mine goes in next to my pens on my shirt) and even set it to beep or vibrate at a dosage threshold of your choice.The meter measures dose rate in Sieverts and I've included a photo of it running next to a Ludlum 19 (which is in micro R/hr... multiply readings on Radex by 100 to get mR/hr. Please consider the scale on the Model 19. I found the readings to be pretty close (15 uR on the model 19vs 0.16 uSv on the Radex and 171 uR on the model 19 vs. 1.57 uSv on the Radex. Next time I'll see if I can get the numbers next to a known calibration source for a better comparison.Anyhow, I'm extremely happy with these results. I like the way the audio tone warns me when I'm in a high-dose area. This item is highly recommended for anybody to keep their dose levels ALARA.

If you expect to see the data over time from the past - there's no way to do this by using the software they are referring to. And it support only Windows (which is Ok). Seems like the software allow you to plot only while it's connected to computer. But I was not able to find the way to plot the graph for the historical measurements.The device does not have internal memory.It can be used as an antenna to stream live data to the software when conducting experiments on radioactive objects, as is the case with jewelers, antique collectors and physics students.

I like that it allows when your near high value materials. I don't like that it turns on in my pocket by itself. The designer should recess the on/off button so this does not happen. Otherwise carry extra batteries, it won't stay OFF in my pocket. AND the plastic clip is a no go. Do Not trust it. It pops off simply. If your back-tracking, it's no big deal. Pick it up where it popped off, if you didn't notice. I've added Velcro to the clip so it stays put where I clip it. For the basic usage, it does what I need it to do.

I just recently purchased and began using this to measure my ambient dose, and to apprise me of any emissions from nearby potential sources during the Coronavirus Outbreak. I am far enough from plants that a Tritium Release is unlikely to show, but there just isn't the level of EPA Enforcement possible at the time. Kind of cool to confirm what background is in my area too. I haven't yet tested it against a known source to verify accuracy.The biggest deficiency of this product (at time of writing I haven't explored the USB-PC Operations so my use has not been complete) is the casing. It should really come with a silicone sleeve, like a Wii-mote has, and instead of a flimsy clip that has insufficient tension to keep on the waistline of pants and broke in the first 3 days, they should have included a quality lanyard to attach (it has one of those set-in loop openings) so the unit can be worn around the neck and rest at center-of-mass where a dosimeter should.I could see this being used by someone getting imagining or other medical isotope applications, to personally track their doses.For my use, and although I have not confirmed the accuracy (it does mesh with what background could be for my location and elevation), I would recommend. Especially given it doesn't break the bank and doesn't devour batteries.

Before I retired I worked in a nuclear reactor plant and wore a dosimeter as part of my uniform. This model is nice in that it gives a live reading of what's going on so you can react to radioactive exposure dangers. It's a very sensitive unit able to read the radiation coming off my uranium glass - a type of antique glass.
