Actually the post is somewhat encouraging. I am surprised that the good guys could detect radiation from Iodine 131.
It would be emitting beta particles and gamma rays. His body the air and the car would stop the beta. It would not stop the gamma rays. It is obvious that the good guys ability to detect low level gamma is better than I thought.
However I wish this information was never published. The bad guys now know that to transport bad stuff will need a lot of radiation shielding. That means a lead box with a lot of lead.
So a man in a car is radioactive enough from the confines of his car in motion to set off abnormal radiation detectors, but we should live in fear of nuke plants that don’t even display radiation levels above background 10 feet from the structure.
“The bad guys now know that to transport bad stuff will need a lot of radiation shielding.”
The bad guys can guess that the CT cops can’t screen out medical isotopes (patients) from threats. In other words, no gamma spectrometer, and they come in very small packages these days.
They also learned that a piece of paper with the right words will get them by a traffic stop, as long as rad levels are what you’d expect from a patient.
