Dear radsafers
    
We found the following two types of exit signs with tritium in the 
Agusta Bell Search and Rescue helicopter (AB 412-SAR):
- "emergency exit", part number CAN-AC40
- "emergency exit, push window at lower corner", part number probably 
CAN-AC422.
(pictures available, but they proved too large for radsafe. Anyone 
interested may ask for them privately)
According on the text on top of the signs, each sign contains 4 Ci of 
tritium.
    
We need information on their construction. Do they contain one larger 
tritium source or several smaller ones?
    
Although the Agusta Bell is produced in Italy, I assume that the signs 
are produced somewhere else (perhaps CANada?).
    
Who can tell me who produces these and/or how they are constructed?
    
Thanks for your help,
