## 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.

### ⭐⭐⭐⭐⭐ R meter

Good meter! Does detect elements. Ty

### ⭐⭐⭐⭐⭐ Tested It On My Cat After Chemo Therapy
*by R***N on November 24, 2024*

The media could not be loaded. My cat just came home yesterday from chemo therapy, for a thyroid tumor. I thought i might use this reader and see what his levels are. Here's a video I did to show how to properly use this thing. I believe it's measured is Rem/h(micro Roentgen's per hour)

### ⭐⭐⭐⭐⭐ Sturdy & reliable with best “instructions” sheet in years!
*by D***O on January 4, 2021*

How long has it been since you read the “Instructions” brochure for an electronic product that was clear, concise and WELL illustrated...in color?? I probably missed it on the Amazon site and reviews, but this a German (!) product with good USA support. The final technician who checked the device even signed the card. Thank you “R. Tonk, Laborleiter.”I checked accuracy and sensitivity with a chunk of uranium ore and it works well. Incidentally, the strongest readings are obtained on the left side near the view screen. It is allegedly water-resistant and that appears to be so, but I am not testing that claim at this time. The device is about the size of a deck of cards but approx 1.5 times thicker. The readout is by necessity small print but quite legible.I can already hear the negative reviewers, “This will be fried by EMP.” Yes, quite right. That’s why you store it along with some extra batteries in a heavy-duty, one gallon plastic bag in a 10 gallon metal garbage can, even in the lab. This gives you easy access and the possibility of increased years of function. (n.b. In the event that you or the device is reduced to nuclear slag, this claim is void.)
