I bought a #scintillation detector from https://radiacode.com. A great super modern radiation detector… it’s like a #geigercounter but with energy spectrum (you can detect the radioactive isotope). For testing I bought a 5x5x2cm #uranglas… now I am testing comparing all my geigercounters from the good radix to the cheap Chinese :-))

At PDX on the way to Montréal for #Scintillation!

My #photomultipliertube test box I made some years ago. Basically a tin box with a lid, made light-tight with adhesive foam made for old SLR cameras. A BNC chassis socket with a bit of coax connects the outside electronics to the voltage divider/socket/PMT.
Shown are the PMT, a test #thallium doped #sodiumiodide #scintillation crystal and a spark gap containing ¹³⁷Cs to generate predictable pulse heights.

How I found the page: I had my own visual hallucination, a kaleidoscope image, first with eyes closed and, alarmingly, persisting when I opened them. The image was superimposed over everything. I seemed to be looking at a baby’s limbs thru a #kaleidoscope, image bright and crisp and spinning rapidly.
I’m guessing it was a #migraine #aura b/c it resolved into a more standard (for me) #scintillation, like looking through flowing water. It was on waking from a vivid dream (not about babies). 4/4

I've had four instances of #RetinalMigraine in the past seven days and it's freaking me out. Anyone else experience this and have ideas of triggers? I have a doctor's appointment but it's not until mid January. Keeping a log of instances until then.

A #gamma spectrum of a small piece of #lutetium metal. With a decent #scintillation probe two peaks of 202 and 307 keV will quickly pop up. #lu176 #radioactivity

My first successful #gamma #spectrometry more than 10 years ago. I got a #scintillation probe and other parts for free from the well-known company #Scionix. Using a HV power supply and a computer with a sound card, a spectrum of ¹³⁷Cs was obtained. #science #radioactivity
