Where from in south Australia?

Crocker’s well or radium hill?

Hi there all, I live in Adelaide and work for the geological survey of south Australia. I’m very familiar with airborne spectra gathered over the maralinga area and have often joked about the existence af “Maralingaite” as a pun on trinitite. After the post I will chase our geologists and see if the...

Hi guys Abilene could be correct. The black mineral is possibly uraninite / pitchblende or davidite. The yellow green flakes could be autunite - which Fluoresces a bright green with SW MW and LW ultraviolet lights. It could also be torbenite - or metatorbenite. This mineral doesn’t fluoresce and is ...

Here is another collection from Australian deposits. Now not available anymore so obviously lucky to have it given to me😊

Source. I plan to run it again in the next few days but do a better calibration with either a thorium mantle or a radium card.

Thanks for your comments, much appreciated,

Cheers and regards

I have read with interest this post from Go-Figure, so decided to run a preliminary experiment of my own. The results are shown below, and the next step is to enhance the lower energy levels. As a background, our house was built in the 1980's above the Willunga Slate quarry in South Australia. The b...

My first attempt at building a cloud chamber - almost ready to try😊

👍👍

Let me know more off your tests.

I’ve been thinking of getting one for ages - and the price is obviously very good😊

Some of the results are for me very puzzling so I have posted them with the hope that somebody can provide an answer. Firstly, the spectra were collected using a Bicron NaI probe, a GS-1100 ...

Hi All, If anyone is like me and is struggling with a Windows Surface pro with no line in jack, or a laptop with one input jack which double as either a microphone or headphone, of like me, you have one of each. Then an external USB soundcard is the way to go. If you require a cheap but reliable dev...
