Include the small geometry of the detectors, and their ability to preserve their track record for almost infinite lengths of time.
The fact that the detectors, in themselves, do not need any electronic/electrical instrumentation means that
they can be deployed under field conditions and in remote, fairly inaccessible places for long durations of time without the need of human intervention or backup, except for initial placement and final retrieval; and their ruggedness is of great merit in making this possible.
Because of its good sensitivity, stability against various
•environmental factors, and high degree of optical clarity, CR-39 ha become the most favored SSNTD
