A pretty spicy Cs-137 Spark Gap tube!
Unfortunately all the markings have rubbed off so I’m unable to identify it but based on the high doserate, I’m guessing the original activity was 5uCi!
If anyone has info on this tube, let me know!

Lead Castle Upgrades 😃

Today the copper sheets arrived for my lead castle to help with shielding XRF. I was positively suprised that even 1mm of copper was pretty much enough to get rid of most XRF!

Next I need to cut out a hole for my probe and make a lid!

Gamma Spectroscopy of dried Mushrooms

While grocery shopping, I found some dried Polish mushrooms and decided to scan them with my spectrometer. After a few hours, a clear 662 keV peak appeared—Cs-137 from Chernobyl fallout!

I recently visited the Berlin Natural History Museum which has this amazing T-REX skull and it appears to be pretty radioactive! What a find! I wouldn’t mind having one of those in my living room 😃 🦖

Working on making some neutron probes using SNM-11 and SNM-32 Neutron tubes. Just waiting for last few components to arrive and I’ll give them a spin!
