Where physical size precludes the printing of re

27、quired data on the lamp itself, each unit package, exterior container, and unitized load shall be marked with the required information in addition to the corresponding military part number as identified in the cross-reference table (see 6.8). In addition, lamps containing radioactive materials shall

28、 be marked as specified in 3.18.1. 3.18.1 Radioactive marking. Lamps with intentionally added radioactive isotopes with a measured radioactivity level less than or equal to 0.002 microcuries per gram shall be considered non-radioactive for purposes of marking.
