It likes running with the smallest Eberline air/vacuum pump. It doesn't need a real "vacuum" to operate, just airflow.? Naturally the filter/sensor arrangement is set up to drawn in air locally, so a

*Loving the articles* and so is a friend! I finally saw sparkling alpha scintillation from a DIY spinthariscope last night and the night before. Was such a victory. I used a small patch of autunite

Sorry for my delay (work's been crazy) -- thanks so much! I'm so happy to be able to read them! To all: I hope an additional few folks will benefit from the resurrection of the articles as well. Dr.

Thanks Geo, and I feel your pain of lesser serviceable things today... well, thanks first of all for the heads up regarding the thick window of the SI-8B. I thought it was closer to being an

Yes rocks are fascinating for sure. Si-88 are good for sure and they don't have the altitude limitations like the US pancake probes do. But the downside is they also don't have alpha particle

Oh boy that will be just fine & righteous -- being able to use one of these units like the CD-700 for up to twice its labeled capacity with a pancake, perhaps the SI-8B with your

Hi Jeff, neat call letters. This is George Dowell, "Geo" a.k.a. Ham Call K0FF. Definitely get a pancake probe. It will find thigs too weak to find with a metal probe and it will do it better than

Greetings and thanks in advance, I'm very happy to have been directed here -- warmest regards. Further below, I introduce myself and give a back story leading to here, but in case you're in a hurry

So I did a survey at work and found no radioactive sources, I did see a slightly higher background count than home. ?It was very similar to home level, and a fair amount lower than the figure I found

That looks like a nice one Brian, we'll have you do an alpha particle test on the sensor one day. Those Russian tubes are really good plus rugged. Geo To: [email protected]

Well I got the detector( Radiascan 701A)?and did a survey of the house. ?Some of the Lantern mantels from the 60s were indeed radioactive. ?I also found some green depression glass that was mildly
