Gamma Scout w/ Alert (Geiger Counter / Dosimeter) – [already sold – sorry]

The Gamma Scout w/ Alert is now so popular, the current backlog means you have to wait 5 months to get one in your hands.  Unless… you WERE the one lucky person who responded to this blogpost first.

See for yourself if the line’s gotten any shorter…, –> which is also where you can read up on all the specifications as well.

My unit:  Sorry, too late.  It SOLD to buyer in H.K. 

(First response, no higher bids came in.)

Perhaps have a look at my list of Geiger Counters and various other equipment that may be of interest to do your own monitoring. 

Well, to look back… I bought mine early, shortly after the Fukushima-Daiichi nuclear disaster in March and had to wait “only” 2.5 months…   In my month and a half of playing around with it (looking at the 12-hour averages is pretty much all I’ve done with it), I’ve mainly seen the cosmic ray influx vary (part of normal natural background radiation), and when flying to Belgium for 2 weddings and vacation, I’ve observed that there truly is over 6.2 µSv/hr gamma ray (cosmic rays) on a Transatlantic flight around 30,000 above sea level.  But honestly, as nice as it would be to hang on to it (just in case, etc.), my focus is shifting and I could use the money right now.  So I’m selling it.   I sold it.

Quick note for Mac users:  The other reason I sold ‘m selling it is because I’m very much a Mac person, and it was a long painful process to get the Toolbox software to work properly at first (GammaScout’s service over email was excellent, though – no complaints whatsoever; with patience, you’ll get there).  My issues seemed to stem mainly because I wasn’t familiar with how things are done on a PC.   (If you’re a PC-user, it should be a breeze)  Anyhow, if you have Windows installed on your Mac, you can use the GammaScout too.  That’s what I did, and I don’t recommend it.  I find Windows annoying and prefer to make my Mac ‘Mac-only’ again.   Thus I can only comfortably recommend the Gamma Scout for PC users.  I still think the GS is among the best for all kinds of projects, and usable as a dosimeter.

It’s sold, so don’t bother to email me…

————–  Below is an example of the data download, though: ———————-

The data can be downloaded onto your PC, and saved as a .cvs  or /txt file, which you can then use in programs like Excel (or Numbers) to do calculations or plot graphs with.  As a text file it looks like this: (current setting:  data stored was every 10 seconds, 3 minutes of data, just as an example of how workable the GS is:)

(use the blue bar to see the dose ratein the far-right column.)  This data you can then graph, which makes the ‘dose rate’ during these three minutes nicely show its fluctuations.  This is why I find checking the 12-hour average (by pressing the radiation symbol key on the GS) much more indicative for “what’s going on” than sample readings.   In Park City the 12-hour average has been fluctuating tightly in a 0.018 µSv/hr band: between 0.188 µSv/hr and 0.206 µSv/hr, generally just below 0.2 µSv/hr.   Spikes of up to 0.6 µSv/hr (during a minute or so) occur as well here at 7,000 ft above sea level.  This is almost certainly normal cosmic ray influx (unless it’s one of them “hot particles” coming to tell me hello…). Unfortunately I didn’t get the GS in time to report on the worst of the radioactive clouds drifting over in March and early April.

All kinds of fun stuff you can do with the Gamma Scout…  This just to show the data from a random 3 minutes on July 20, 2011 (above) in graph form:
