Single use medical does of iodine 131 are in the 3 to 300 mCi range. Since a Type A quantity is 13.5 Ci, multiple dose shipments can be made without using a Type B packaging. However a bulk shipment, such as would be made from a source producer to a pharmaceutical processor, could easily involve 120 Ci (about one mg) which is 9 A2. This falls in Category III range, so even though a Type B package is required, its containment boundary need not be designed to ASME Section III.

For thallium typical diagnostic doses are about 3 mCi. With the Type A quantity at 270 Ci, a Type B package would not be a consideration.

Cobalt 60 radiographic sources are in the 100 Ci range which is well above the 10.8 Ci Type A limit so a Type B packaging is required; however, again a Category III package is sufficient and ASME Section III need not be involved. A cobalt 60 irradiator may use a 15,000 Ci source which is about 1400 A2 which puts it into the Category II range. A larger irradiator may well exceed 30,000 Ci and require a Category I packaging which would require an ASME Section III containment. Note that for cobalt 60 the A1 value is the same as the A2 value so there is no shipping Category advantage to encapsulating the cobalt into a qualified special form.

Finally the typical smoke detector has one micro curie of americium 241 so enough americium for 5400 could be shipped in a Type A package. (A Type A quantity is 5.4 mCi.) Larger quantities would require a Type B packaging, but again this would be Type B Category III packaging not requiring an ASME Section III containment.
