RE: Type A transport containers
Thanks for all the info so far. Some more more
important info about the source and container. The
source is special form (296GBq) and is surrounded by a
stainless steel sheat at the centre of the shielding.
The container is also used for storage when the source
is used at temporary work sites. The TI is 3.0. The
cost of each container is in the region of $1500.
This particular container is 6 years old.
