21. A method for detecting breaches in a container, comprising:
providing a tamper detection system, comprising;
at least one optical energy transmitter;
a material for transmitting optical energy from said at least one optical energy transmitter; and
at least one detector for detecting a change between an optical signal transmitted from the at least one optical energy transmitter and an optical signal transmitted through said material due to an intrusion in said material;
