## Description

RADEX RD1503+ with Dosimeter (Outdoor Version): High accuracy geiger counter, nuclear radiation detector: desertcart.com: Industrial & Scientific

Review: Pretty cool - Great device. My son and I were able to measure ambient radiation from sea level to the foothills of Colorado along with 32,000 feet in a commercial airliner. All readings seemed reasonable. We also measured radiation in our house including on granite counter tops with visible kspar. All readings were reasonable. After a while it wouldn't start, but replaced the original batteries and all is well. Update 4feb2023 I've only used the device a few times a year. Still working great. My son has grown a lot and built a mightyohm geiger counter with an SBM-20 Geiger-Muller tube. We picked up a bottle of uranium ore on desertcart and readings from each counter, measuring both ambient and adjacent to the U-ore are nearly the same. Now we're working on a true random number generator based on radioactive decay that can interface with software running on a laptop. How random.
Review: Checked against a calibrated laboratory unit. It's good. - It's only like, .02 off here n there, it takes multiple readings though out the course of 30 ish seconds and compiles them into one reading, making it a lot more accurate than others I have used. It's simple, It's light weight, it's tiny, it's orange so you won't lose it, its... perfect. And for the price point... AWESOME deal. Very decent unit.

## Questions & Answers

**Q: Can it detect all of "alpha", "beta", and "gamma" ??**
A: The seller's wholesale dismissal of alpha radiation is irresponsible at best.  Just for a quick example both Radium-226 and it's decay product, Radon-222, decay purely by alpha radiation as do the other two naturally occurring isotopes of Radon.

While it is true it's not likely that one would use such a dosimeter/geiger counter to detect Radon, it would be used to detect Radium, which still can be found in vintage watches and older medical equipment.

**Q: Why do they show it in use near hv transformers?  does it also detect em emissions in that range?**
A: No, you would need and EMF (electromagnetic field) detector for that:
https://www.amazon.com/Advanced-Electro-Magnetic-Detector-Monitor/dp/B007ZBETWC/

EM emissions are non-ionizing radiation, which means the particles do not have enough charge to cause damage to tissue.
Geiger counters detect ionizing radiation, the dangerous kind: Alpha, Beta, Gamma, X-ray, etc.

I hope this clarifies matters a bit!

**Q: What is the difference between this model and the RD1503+ without dosimeter model?**
A: This model does have the dosimeter function (see "DOSE" on the LCD screen), which means that it can switch between immediate radiation levels ("NOW") and accumulated dosage over time ("DOSE").Very useful when working in environments with even slightly raised radiation levels (warehouses, junk yards, granite canyons, treatment plants, etc.)

**Q: Is this detector EMP proof?**
A: As a former designer of electronic circuits, I can opine with 99% certainty that it is NOT EMP proof. I say that because the outside is plastic (a non-shielding material), and the LCD screen also would not block radiation. I think to add EMP protection would raise the cost considerably!

 FYI, I store my detector, when not in use, inside a metal container (with other electronics) because of its vulnerability to EMPs.

### ⭐⭐⭐⭐ Good meter and some clarifications
*by S***P on May 13, 2022*

I purchased this unit because of the various reviewers that had generally confirmed accuracy of this meter relative to commercial-grade equipment (Ludlum). I'm satisfied with the operation and limited results in use so far: (1) background in suburban/rural area of Florida = 0.1 µSv/hr; (2) thorium "check source" consisting of lantern mantles quickly set off the alarm and pegged the unit at 9.99 µSv/hr (or 999 uRem, depending on which units you are using). FYI: EPA's recommended 1-year exposure limit is 1 mSv (1,000 µSv) or 0.11 uSv/hr, and EPA's lowest 1-year dose linked to increased cancer is 100 mSv (100,000 µSv) or 11.4 µSv/hr. Note that there is a YouTube video that appears to be this unit (orange) exposed to various radioactive sources that shows the digital readout climbing to as high as 999 µSv/hr (and automatically switching units to mSv/hr). This would be great, but it is not this meter (there is a more costly unit from QUARTA that does have this capability). The display on this meter maxes out at 9.99 µSv/hr (= 999 uRem/hr), as indicated in the specifications. Also note that all of the QUARTA rad meters are apparently manufactured in Russia, which may influence your purchasing decision given the current Ukraine situation...
