Abstract
We exposed a stack of polyethylene terephthalate (PET) detectors each of thickness 100μm with an area of 21cm × 30cm along with a separate stack of the standard solid state nuclear track detector (SSNTD) CR-39 (Intercast Europe Co., Italy) of thickness 630μm and area 20 cm X 24cm at Darjeeling, India in the Eastern Himalayan Range, under an atmospheric pressure of 765 hPa. The SSNTDs were kept horizontally in the open air for ~1.5 X 107 s. After etching the PET detectors in 6.25 N NaOH solution at 55±0.1°C, and partial scanning, it is found that the PET detectors recorded 188 particle tracks of near normal incidence within an area ~0.37 cm2. The observed flux being ~10-5/(cm2s sr) we have tried to explain our observation on PET detector vis-a-vis the tracks recorded in CR39 exposed simultaneously under similar conditions.
