Kvarts DRSB-01 Review

Mental Socket DRSB-01 Review

My Review: EXCELLENT! Although it is not a dosimeter (it only measures rate), this is an excellent Geiger Counter. It is very sensitive, seems to be built pretty strongly, and has both loud audio and video output. I love mine - at this price, it is a giveaway! Buy from annakozub on eBay- it takes awhile to get here (US), so be patient. Best packaging ever, bubble-wrapped to the max.

This unit measures background counts of 30 CPM, just like my Geiger counters that cost over 10 TIMES as much.

Type: Dosimeter Geiger Counter

Manufacturer -
Kvarts

Power = (1) AA Battery



DRSB-88 Review


My Review: EXCELLENT AGAIN! Although it is not a dosimeter (it only measures rate), this is an excellent Geiger Counter. It seems to be built pretty strongly, and has both audio and video output. It is really small. I love mine - at this price, they are giving it away! Buy from annakozub on eBay- it takes awhile to get here (US), so be patient. Best packaging ever, bubble-wrapped to the max.

This unit will NOT measure low background radiation counts of 30 CPM. It produces about 1 CPM. However, when the radiation gets high, it works just fine.

Meter= 0 ~10mR/hour (milliRoentgen)

Manufacturer -
Sper Scientific
Source Country - Scottsdale, AZ

Power = (1) 9V Battery


Disadvantage: There is no "On" switch - just a square "Push-to-Test" button. Holding this button down gets old really fast! This unit is for quick checks, not for survey.

NOTES:
*Geiger counter: Measures intensity of radiation (rate)
*Dosimeter: Measures intensity of radiation (rate) AND accumulated exposure over time (dosage). A dosimeter may be based upon a Geiger counter, or upon an ionization chamber counter, quartz fibers, or other technology.


eBay - New Low-end Units
Initially, I dismissed all the Russian Geiger Counters as "too far" and "problematic". My eyes have been opened - I love mine. The best deals seem to be Russian, and all with a flat, worldwide shipping fee - $9.00 US. Note that other types of Gieger counters (sic) are available on eBay, but the low-end devices listed above are all new devices, and are the most popular (available).

eBay - Used High-end Units
High-end Geiger counter units such as Berthold, Bicron, Eberline, and Ludlum are usually sold as "used, working", or "as is" (your top bid should be much lower). Some come without a required external probe. "Don't know" or "can't test' is a red flag. It may be honest, it may be deception. Look carefully at the seller's rep. I avoid anyone under 99%. I prefer 99.7% or better.

Hint: Decide how much you are REALLY, REALLY willing to pay for a used unit, at least 1 hour before the end of the auction. Don't let the heat of the moment decide your last bid. Because the winning bid is usually determined in the last 30 seconds of the auction. I'm a six-time loser in the last 30 seconds. Do your analysis early, and then bid and forget. Decide the $, early. Bid only half as much for "as-is" items. In some cases, "as-is" means "doesn't work" - some folks are not as honest as they pretend, nor as forthcoming as they should be.


Antiques, but still in use
Some Civil Defense Victoreen antiques from the 1960's -
CDV-700 - Geiger Counter - These are capable of detecting low-level radiation - built-in check source.
CDV-710, CDV-715, CDV-717, CDV-720 - Ionization Chamber Radiation Detectors - Useless, unless bombed

For years, we were told that low-level radiation won't hurt us. Most scientists now concede that ANY amount of radiation CAN be harmful. Radiation damage is accumulative. Reduce your total exposure.



DISCLAIMER
Although the author has tried to be as accurate as possible, errors are possible. Prices are continually changing, based upon varying supply and demand.

I could not find a Geiger counter summary like the above. So, I made this ionizing radiation detector comparison chart, to help myself understand the technology and pricing available. I hope that it helps you.

I am an electronics engineer by trade, who knows little about nuclear radiation.
