Proton Detection with CR-39 Track Detector
Radiation Protection Dosimetry, 1996Hungarian produced CR-39 detectors irradiated with protons of energy 3-18 MeV and with 14.7 MeV neutrons through a thick PE radiator were etched at 22°C and 70°C in NaOH solution. The increase in diameter of tracks as a function of proton energy was measured.

The Effects of Storage on CR-39
Isotopenpraxis Isotopes in Environmental and Health Studies, 1991The effects of storage temperatures on the track registration of CR-39 as a solid state nuclear track detectors have been investigated. The results show that the storage CR-39 detectors cause partial or complete removal of tracks depending on storaged time and temperatures. The bulk activation energy for CR-39 has been found to be 0.883 eV.

Plate-out effects in CR-39 detectors
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1985Abstract A study of “plate-out” effects in CR-39 detectors in indoor environment was made. The detectors were exposed to airborne particles, settled down onto a surface placed at various distances from the detectors. The effect was estimated to be about 30% in indoor air.
