Much of what is being discussed is still speculation since it is not really known how long the unit has decayed. If it 30 years then only about 3% of the original activity will remain. If the original activity is 3,000 Ci then the remaining source would only be about 90 Ci and it would only be a category 2 shipment. The US rules for category 2 would not require real time tracking of the vehicle but only package tracking so you would know that it had not arrive at the next point at the expected time. I would say that for this incident there was early knowledge that something had happened and that is the best one could expect within the US regulations for a category 2 source.
It is not clear to me that the persons involved are "doomed" but I would rather tell the news media that and see if the individuals involved are scared and seek help. At 90 Ci the source would only be reading about 21 R/min at 1 foot so it is not likely that they would have received a fatal dose. But as I said this is all speculation. I am going to be interested to read the detailed accounts of this incident.

In the USA it would be unlikely for a truck with Category 1 quantity of radioactive material to have gone missing. See 10 CFR 37.79, Requirements for physical protection of category 1 and category 2 quantities of radioactive material during shipment.

Hello John,
I would not presume that this kind of incident or others would not happen here in the USA or any other country. Things do happen and we have seen those things happen in the past. I would never state that there is no potential for a source to be unattended. For instance, there are numerous notices where department of transportation sources are stolen from government vehicles.
Regards,
Sandy

It would seem that a shipment like this would not be left unattended so that theft is "highly unlikely". Not trying to start a new thread, but I haven't enough experience in source shipment to be able to explain how we prevent this kind of theft.
