The DRSB-88 is a very
Detector Made in Russia. I purchased it on eBay. (Link
After reading a nice review of another model, (Link
) and finding
no other information about such devices elsewhere, I decided to write a
review of my own.
Pocket Gieger Counter
The unit is one of the the smallest (and least expensive) true Geiger
have ever seen. Update
There are several "Keychain" detectors now available. To read
review of one of them, see the links section at the bottom of the
page. What I wanted was something small and easy to carry.
The obvious device for such a purpose is a Dosimeter. I am very glad I
got a true Geiger Counter instead. What's the difference? See Link
The DRSB-88 is almost as small as a Dosimeter, yet uses a
easily replaceable battery (One AA Battery.) This
very important in a Civil Defense emergency. Instead of
estimating dose, the DRSB-88 gives indications of individual counts.
Background counts soon give assurance that the device is working
properly each time you turn it on. It also seems that the battery life
is very good.
While somewhat privative in construction compared to most
electronics, it seems fairly sturdy. I have already dropped
twice from my shirt pocket onto a tile floor, and it is still working
The unit lacks any sort of readout or meter. It's
simply a light and a clicker. In the presence of a
threat, the rather bright light would flash enough to be very obvious.
The “click” sound is exactly what people expect
from a Geiger Counter.
If I am near anything that produces anything noticably more
than background counts, I am going to take steps to increase the
distance between myself and whatever it is as soon as
the Milliroentgens, Radiation Absorbed Doses (RADs), and Exposure Limit
Charts to the proper authorities. If you want to quantify what you
detect, the DRSB-88 and a stopwatch will give counts per
By the way, does any body know what exactly that light
does not look like an LED. Is it some sort of neon
Sensitivity: With no readout or meter, speaking of
irrelevant. An important thing to note is that the GM
(Geiger-Muller) tube in the DRSB-88 is very small. Because of
this, fewer ionizing particles are going to pass through it than would
though a larger tube. My DRSB-88 seems to detect about
the counts as my old Universal Atomics V-700 Commercial
This does not mean the DRSB-88 is inaccurate or not
times background still means 10 times background, and that means you
have a problem.
Dr. Covington asked the rhetorical question: Have I found
radioactive? He did, and So have I. I
have a clock
out of the instrument panel of an old aircraft. It has a
dial, and it makes the DRSB-88 go crazy.
