  • Description

    Type 7770 cards.  These are cards from which the TLD-600 was removed for reuse.  They still contain the elements 1, 2, and the thin E3 for beta dosimetry.  They are the equivalent of the type 1110 card, but have the advantage of being insensitive to neutrons since the elements are made of TLD-700 material (Li-7F)
