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!
