Re: HPGe detector back to life after long sleep

There are quite a few on ebay, most based in US, which makes them even more difficult to get, since shipping will be 300+$. Also there is a working one for 4000$ from italy, the seller even offers to demonstrate the device and deliver it personally :) but 4k$ is alot. Here is a quite extensive repor...

Re: HPGe detector back to life after long sleep

Very nice detector, and extremly fortunate for you that the detector still works without any work. I'm wishing for a HPGE for a long time, but i was advised by Carl Willis (maybe some of you know his blog) that HPGe's can in very bad condtion, even if they are sold at a high price. Most sellers know...

Re: Pushing an Arduino to the limit.

If you need a more "boosted" arduino, take a look at the new models, they come with ARM Processor which is much more powerfull (48Mhz instead of 16)

Scintillation Crystal conversion

After looking for the perfect radiation detector, i've come to an end and accepted that there is no ultimate device for the hobbyist. I'm looking for a high-tech device (logging, gps, external detector capability etc) but there are only a few, and these are priced for professionals, which means abov...

Re: Orvieto - High Natural Radiation Background

First of all, i really like the first photo, very nice work. What camera you use? About the gammas, as far as i know, pozzolana and tuff are volcanic ashes or lava rock... do you know if only the volcanic ash in that place is slightly radioactive, or if all volcanic ashes are this way? I'm wondern b...
