truck placard
The shipment placard is for accident responders... It is not for you to stay away from the truck... the radiation exposure rate at the surface of an unbroken package should be no more than 1,000 mR/hr at time of shipment and even this is worst case scenario. To put this in perspective you get an annual dose of around 2,400 mrem from Radon daughter products you inhale.... in your home!
Depending on the material being shipped, they have different dose rate limits... White I, Yellow II and Yellow III with a maximum rate of 200mR/hr.
Then there are the shipping containers themselves.... It just gets more complicated from here
(1 mR/hr is about 1 mrem where mR/hr is exposure rate and mrem is exposure dose.)
The truck is safe, no need to worry.

BTW, this national average (~360 mrem/year) is about the equivalent of 60 standard chest x-rays...or about 1/4 of a full body CT scan.

I looked up 2908 in our DOT emergency response guidebook and it's very low radiation stuff and empty packages capable of carrying very low radiation stuff.
Basicly, it's nothing. It only recommends us to wear our bunker gear and SCBA, which are not designed to block radiation at all. It's probably something that emits alpha particles at best that a normal T-shift can stop and even if you did get "exposed" probably nothing would happen.

that placard like said above is for an accident...
that gives whomever a is there first the knowledge of how to respond....open the truck door and get the hazmat book(if its not burned up or something) and flip to the section matching that placard and you will have a brief explanation of what to do etc...
Damn im rusty on my hazmat stuff
im glad i never got the hazmat endorsement, too much crap to remember, not to mention the liability

Its not so much the radon gas thats bad, its the daughter products associated with the gas thats dangerous when inhaled...
200 mRem is correct for radon gas in a total body exposure, not inhaled.

Basically its nothing to worry about. Like stated in a accident even if it did get all over the place a minimal amount of protection would be recommended.
Now say this thing had escorts and as stated before there were specialized containers that basically sheilded you from the radiation coming from the container then yeah that is something not to mess with.

Lets say this truck is flipped in a ditch and you come accross it. You notice that there is some fluid coming from the back or through a crack somewhere. This should not stop you from assisting with any injured person at the scene. This should stop you from addressing the spill itself. When calling for help it is important that you describe the placard and spill so that the proper personnel can arrive.

if you can get to the cab of the truck in an accident the BOL is required to be reachable by the driver strapped in the seat, or reachable from outside the door (either on the seat itself or in the door pocket) on a BOL for any hazmat load including radioactive there will be a emergancy response number you can call and detailed information about that load will be on there also.

For what it's worth, most smokers recieve about 7 times more dose to the bronchial epithelium from the Po-210 found in tobacco than the average person does from Uranium or any of its daughters, which is about the equivalent of 2000 regular chest x-rays for a heavy smoker.
Thanks for the info, I have not read much about equivalent dose delivered from radon as it isnt clinically used to treat cancer.
BTW, what do you do that you know so much about the transportation of radiation?
