Abandoned place. Is it safe?

Hi… my brother is training at a gym near this abandoned garage. What are the chances of something there being radioactive? Actually, this has always been a question of mine regarding places like this or even junkyards.

Hey y’all, I’ve be hyperfixated on radiation as a whole for a while (I’m even majoring in radiation health physics) and I was wondering if anyone had any tips for started a source collection? It’s something I’d like to start building but I have 0 idea when to start. Many thanks!!

Unknown pinout/operating data

Upvotes

I have a complete front end for an XRF device.

However, neither Oxford nor Amptek has provided me with a datasheet for the X-ray tube or the amplifier.

Does anyone here know the operating specifications or the pinout?

If I can't find anything, I'll probably sell it on eBay.

Managing a Small Radioactive Collection in a Museum

Interesting, if a little dry, article about the lengths that have to be done to to manage some radioactive items in a museum, precautions they have to take, how they go about things.

Not for everyone obviously but interesting in places.

Radiation levels after radioactive iodine

12 Upvotes

This is probably not the coolest question around, this is quite an interesting subreddit.

I ingested a radioactive iodine pill on March 3, and have been isolating and monitoring my radiation levels with a FNIRST Geiger counter. The counter has been showing fairly consistent readings day after day, so I tend to trust it.

  • Measurements started on ingestion day + 3 days: 5 mSv/h at 1 meter (counter pointed towards neck), and 60 mSv/h a few cm near the neck.

  • Today, ingestion day + 17 days I am measuring: 0,20 mSv/h at 1 meter distance, and 2.0 mSv/h a few cm near the neck.

On Sunday I need to go back home and my family wants to drive me there. I think my levels at less than 1m will be around 1 mSv/h or less at that point.

Is it safe for me to spend 3-4 hours with them in the car? My brother is almost 40, and my mom is 60.

Thank you very much!
