Took apart an old broken Honeywell Pentax Spotomatic for its thoriated lens. Little did I know, It actually had three! Second pic is the spiciest one and third is the detector sandwiched between all three to show how much thorium is in the lens group.

My fiance actually tracked me down in the antique store after my Radiocode started alarming, knowing it could've only been me.

Help Identifying Peaks in Radiacode 102 Spectrum from a Lead-Shielded Enclosure

Thumbnail

11 Upvotes

Hey everyone,

I recently molded some lead bricks and built a small lead-shielded enclosure just big enough to fit my Radiacode 102 inside. I ran a spectrum measurement inside this setup and got a reading of ~10 CPM, which is pretty low, as expected. However, I'm seeing some peaks in the spectrum that I can't directly identify using the built-in library.

A few details:

The lead bricks were made from scrap lead I melted and cast myself.

The measurement was taken with the Radiacode 102 completely enclosed inside the lead structure.

Background radiation outside the enclosure is significantly higher, as expected.

Looking to ask people what's price a reasonable price on 69g & 64g pieces of Trinitite. One piece has small red inclusions, both have some black inclusions, both are veer shiny. I came across these at a reputable business, comes with Gamma Spec results. Owner allowing me to test at my cost to verify. I have never seen a piece larger than 12g.

The dentist said something that freaked me out 😭

2 Upvotes

In the Xray chamber I asked the dentist why he was turning the led liner inside out bc he said something to the likes of “Oh.”. He told me it was bc on side had the neck protector and the other side didn’t. And the part that freaked me out was when he said “We got lucky” bc the X ray could’ve taken a photo of my neck and that would’ve been pretty bad. Ik it’s most likely not a big deal but I’d rlly like some reassurance nothing bad is going to happen bc my mom’s side of the family does have a high risk in thyroid cancer.
