From the manufacturer
RADEX ONE compact, personal Radiation Detector for everyday life.
Radiation dosimeter is designed to measure ambient ionized radiation, as well as radioactivity of materials and products, and the accumulated radiation dose received.
Exceptionally calibrated, scientifically-tuned engineering equipment for common use.
The newest model from the RADEX brand - since 1992.
Beta, Gamma and X-ray detection - the dangerous ones.
Alpha radiation particles can't penetrate a sheet of paper or a layer of skin. Beta and Gamma (X-Ray) radiation goes though much tougher materials.
RADEX ONE is specifically calibrated to detect and alert about dangerous radiation.
Uses low-voltage SBM-20-1 Geiger-Muller tube (the sensor) for detection. Calibrated with Cesium-137 isotope in our lab.
Ambient Radiation dose and Accumulative dose
One of the great features of this handy device is the Accumulative Dose mode, that shows how much radiation was detected over time, and not just immediate results.
Accumulative dosage is important and a rare feature for radiation detectors: most show immediate radiation levels only, and not prolonged exposure.
See what you have been missing.
Radioactive materials are used in many consumer products. The most common of these is some smoke detectors which use radioactive Americium-241 to detect smoke particles in the air.
Other sources: natural granite, tobacco smoke, medical procedures such as Thyroid Radiation Treatment and contaminated produce.
Normal levels (sea level) are 0.10 - 0.30 uSv/h

Pros: Small, discreet, light weight, very easy to use, works great. Audio and adjustable level alert. Battery life is fantastic ~ 19 days. Measured a known test source and the unit was very accurate. Shows current levels, and accumulated dose. PC software for data logging. Excellent buy for the price. I would buy another.
Cons: No back light on the display. The display may be a slightly difficult to read for older people.
Helpful hint: It has a lanyard but if you carry it in your pants pocket place the clip the front button side to help keep it from turning on.
Update:
It was about 3 months after I purchased the Radex One that I had a minor problem. The secondary clear protective cover that protects the LCD screen detached from the unit. It is held in place by a clear glue. I emailed Quarta Rad with the Amazon order info and asked for a replacement LCD cover. The Regional Manager, Dmitry replied that the Radex One had a 1 year warranty and they were shipping out a new replacement unit, and to simply ship the old unit back usps. I received the new one 2 days later. Wow talk about fast and eager to please, these guys went way above anything I expected. If you need a compact accurate Geiger / Dosimeter at a good price, this is definitely the one to get. Quarta-Rad, you ROCK!
I have had this unit for a year now. The Radex One is a perfect grab and go unit. The compact size makes it very easy to take along, and discrete to use. The fast 10 second response time for the first reading is impressive with the best reading after 30 seconds.
The sensitive internal geiger tube runs virtually the length of the unit, which places it in class with much larger hand held units.
There is a vibration and soft audio alert that can be enabled as well as an adjustable received dose level alert. The battery life
is fantastic ~ 19 days of continuous use with an energizer battery. I measured a known test source and the unit was very accurate,
within a small percent of a unit that was 4 times as expensive. The display shows current levels, and accumulated dose. PC software
for data logging. Excellent buy for the price. I would recommend it for anyone and I would buy another.

Keep in mind that the upper limit on this device is around 1 mSv/h. This is more than enough for assessing the consequences of more distant radiation accidents, for playing around with uranium ore samples, or for testing food or soil, but - it is probably not the kind of a detector you want if you're seriously worried about living through some kind of a nuclear apocalypse, since it maxes out way below levels that are immediately hazardous to life.
Oh, be mindful that this thing has a tiny LCD display, and that you need to crack open the manual if you want to change any settings.

Da ich leider schon mit der Alterskurzsichtigkeit zu tun habe, muss ich durch die Lesebrille (oder den Leseteil der Gleitsichtbrille gucken) sowie mit einer starken Taschenlampe auf das Diagramm leuchten um erkennen zu können, ob ich jetzt den einen oder den anderen der zwei Schalter auf dem Gerät drücken soll.
Die französische Gebrauchsanweisung ist zum Glück einen Ticken größer und ich kann zum Glück auch Französisch.
半年経過頃よりエラー表示が頻繁に出るようになり、電池交換しても改善されなかったので購入したショップへ問い合わせたところ、修理ではなく無償で新品と交換してもらえました。対応も早く、非常に良いショップでした。
