EcoTest MKC-05




My Teppa-n (Russian version but just like yours) does that too a few times a year. Suddenly it goes high and alarms and then usually goes into a rest mode and it goes right back down to normal. I am not sure if it gets hit by real radiation from space, some big atomic particle nearby splits, or if the aliens are just taking a flash picture :D It might also be some weird quirk in the unit's software or detector. But I would call that "normal" whatever it is so don't worry. If it stays high for an hour then worry but those sudden short bursts happen to mine here too. I knew of an older detector unit that did that too but that was 30 years ago before they had software.

I Googled a bit and Gamma-Ray-Bursts seem like a possibility:

"...On July 2, 1967, while monitoring nuclear weapons testing, the U.S. satellite Vela suddenly detected intense gamma rays. This finding must have caused its observers some alarm, since the time was the era of the cold war between the U.S. and the Soviet Union. However, the source of the gamma rays did not lie on the Earth, but in outer space.
"This was the first observation of a gamma-ray burst," explained Dr. Makishima...."

This has happened to me long before the Fucushima thing so it is not that.

Phoenix, Arizona - Last Reading 4/16/11 1030 hrs 16 CPM (Previously 14 CPM)

wind = N 4 Mi/h
temp = 81°F
avg = 15.7 CPM
std = 1.6 CPM

The GeigerCount java program now includes data logging, one data log entry per minute. Next to implement is the alarm. I found a cool whoop-whoop from some recorded airplane cockpit sounds.

Neat! Is it open source?

Big hugs to all of you! Appreciate your extensive efforts... Please keep us posted from time to time. This certainly isn't over yet.

Phoenix, Arizona - Last Reading 4/20/11 2030 hrs 15 CPM (~=0.248 µSv/h) (Previously 17 PM)

wind = W 9 Mi/h
temp = 84°F
avg = 15.7 CPM
std = 1.6 CPM

Software now working in all modes, with a few odd issues. Logging and audio alarm now working properly. I'm creating a project on sourceforge.net and will post a link to it when necessary documentation is ready.

I live in Massachusetts and today our local newspaper reported that, "In Massachusetts, small amounts of radiation associated with Fukushima were reported in rainwater at the end of March, but the levels in the air are more recent developments"

I can't post a link because of copyright hassels, but a search should pull it up. The headline is, Radiation traces in air.

Exactly whats required here
