## Questions & Answers

**Q: Will this device be just as effective in radiation detection if it's inside a shirt pocket?**
A: Works just fine in a shirt pocket.  Great thing is that is is cumulative.  Excellent features for the price.

**Q: This is scaled to detect exposure in the µSv range.  Can it be switched to detect exposure in the Sv range?**
A: No, that would not be practical. Sv (sievert) range is abnormally high - it's Chernobyl-level exposure and instant radiation sickness. 1 Sv (sievert) = 1000 mSv (millisieverts) 1 millisievert = 1000 uSv (microsieverts)In most households radiation levels are circa 0.20 uSv/h (microsieverts per hour)Illustrated article with real-life examples is here:https://www.allianz.com/en/about_us/open-knowledge/topics/environment/articles/110407-radiation-how-much-is-harmful.html/

**Q: what is the difference between this version and the outdoor version that costs $2b more?**
A: I don't have the outdoor version, but I would expect that it is more ruggedized.

**Q: Does this also detect and measure Radon gas?**
A: Radon gas emits Alpha radiation, which Geiger-Mueller detectors cannot see.  The Alpha particles will be stopped by the casing of the detector and will never be counted.  If you really want to detect Alpha particles, you need a "scintillation" detector, that will have a microscopically thin window to allow the particles into the detection chamber, typically of an aluminized mylar sheet.  This detector states it will detect beta type and gamma / X-ray radiation only.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome and Easy to Use
*by B***N on 22 December 2017*

I spent a lot of time brooding over which radiation detector to buy and eventually settled on this one. I think it's awesome. I've had it for several months now and it works great, cycles fast, came calibrated, and it's slim and fits in my pocket. I don't carry it everywhere but when I first bought it I would keep it in my jeans pocket, as it's slim and since the display is on the top you can just glance down to read it and don't even have to pull it out. I'm very pleased and I found their customer service to be excellent, as they responded very quickly to some questions I had about the software (which also works really well).This was my first radiation detector/dosimeter and I definitely think this was the right one to pick!

### ⭐⭐⭐ Its good but not great
*by M***P on 5 June 2019*

First the Pros :small and compact, easy to operate, shows total dose, current dose rate and counts per second.And the cons:The warning beeper and vibration are woefully quiet/weak if you are anywhere except a totally silent room you would not hear the alert (bit of issue if you are trying to keep away from anything that may be a source).The connection to a computer for data display is laughable, the unit stores no data at all!! when you hook it up to a computer it only displays the data from when you hook it up meaning a small portable device can only record data if it is hooked up to a not so portable computer with a USB leadThere is no Max dose rate feature, look even garden digital thermometers have a feature where you can view the max and then reset it, it would have been really really handy on this as you could have seen if there was anywhere since you last reset that gave a high instantaneous dose and maybe you shuld go an have a check.I know the argument is that you get the same functionally from a film badge, it gives you total absorbed dose and does not let you know what is going on at that moment, but this device could do that and quite frankly it should do that without having to stare at it constantly (or have to keep it gripped in the palm of your hand so you can feel it vibrate as anywhere except for a silent room you won't hear it beep)So it does its job but it could be so much more useful.

### ⭐⭐⭐⭐ Very small, very fast, very expensive
*by R***U on 28 April 2019*

Honestly I like it more than I thought I would, it fist like a pen in the pocket of your shirt, I wanted this due to Fukushimas ongoing problem .. a bit of peace of mind, I tested it on my old smoke alarm in my house and it worked great, I got a reading of 20 microsiverts so I got rid of it.Pros: very accurate, connects to the pc instantly, very fast response to radiation.Cons: price quite high but on this level of accuracy it costs money, very small lcd, hard to read, and also a headphone jack would be great as the sound scares people and the vibration is to low.I would recommend buying this if you worry about your family in a world with Fukushima ongoing for a long time..
