CR39
Solid State Nuclear Track Detector
CR39，as the most sensitive SSNTD till now, has been developed and applied in many fields, such as, environmental Radon(air and water), geology (radioactive investigation), health physics(neutron dosimetry), nuclear physics(neutron spectrum), spaceflight(cosmic ray) and track treeing mechanism and its application in material science, fracture mechanics and isolation of polymer etc.
