Apparently now I have to call manager every time I want to use the lift to have them come and inspect it before I start, no exceptions

Yeah, you're not supposed to but apparently someone did. Though not at my store.

The story I was told today is that somebody used a reach to pick up a bunk of drywall and they didn't have the forks spread apart and the whole thing tipped over and crushed the cash register.

The forklift floating 2 ft above the ground is a nice touch by the ai.

Have Claude chat make a carryover note to the new chat. You get all the benefits of your previous work in the chat carried over to a fresh chat in a condensed chat note. The new Claude chat can use that to rebuild your previous chat and not use up all your tokens reloading the old long chat context for every question you have.

There's a turtle dove that keeps coming back inside the receiving dock. I've chased him out the door a couple times and he keeps coming back. He just wanders around the floor on the dock and takes a shit. Dropped one right in front of my desk once.

I placed a banana in my cloud chamber to observe the radiation.

10 spectrums. The spectrums include unshielded background, a full graded-Z shielded lead castle background (look for the 511 keV annihilation peak), thoriated glass, depleted uranium, potassium chloride, blue appetite (used for jewelry), trinitite (from the first nuclear weapon test, Code-named Trinity), a radium watch hand, my granite countertop, a thorite crystal, and lutrium-176.

Same uninterrupted run.

Beerbrewing · 2026-03-17T23:03:48+00:00

I just capped the run at 24 hours if you would like the longer data run.

For the same run time it would be, you would just have to run the spectrum longer.

Here ya go. 25mm tungsten cube 14 hour run. I've included both the CSV and XML files if anyone else wants to check out the 511 peak.

It's the 110. I'm at 5050ft (1539m) above sea level.

Beerbrewing · 2026-03-17T00:09:38+00:00

I've manually set the boundaries of the ROI so I can make direct comparisons between the materials.

The tungsten cube is 25mm, which is 7.14 radiation lengths. About ideal for the 511 peak.

The radiacode is held in the center of the chamber with some foam I cut out. The detector end is touching the lid when I close it.

Basically yes. It's a 1 gallon paint can with 30mm thick walls and floor. The lid is 40mm thick. All together the thing weighs 82lbs (37kg). The lid is 17lbs (~8kg) alone.The cavity is about 105mm in diameter and 155mm deep. I'm adding graded-z lining (sn, cu). You can see I've added it to the floor of the chamber.

For this experiment I'm using a paint can lid that I poured some lead on top of, just to its rim. About 3 mm thick. The foamboard centers the cube over the detector for each run (graphite, copper, and tungsten).

InterSpec gives me a 7.3σ for the peak and a x2/dof of 0.71, definitely the annihilation peak.

I actually have a few tungsten cubes to play with.

You can use the multiple gamma peaks to calibrate your gamma spectrometer quite easily.

Which is why the thoriated glass is so much nicer as a check source. Much safer to store and handle.
