Abstract
We exposed a stack of polyethylene terephthalate (PET) detectors each of thickness 100μm with an area of 21cmÃ30cm 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 20cmÃ24cm 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 â¼1.5Ã107s. After etching the PET detectors in 6.25 N NaOH solution at 55±0.1âC, and partial scanning, it is found that the PET detectors recorded 188 particle tracks of near normal incidence within an area â¼0.37cm2. The observed flux being â¼10-5/(cm2ssr) we have tried to explain our observation on PET detector vis-à -vis the tracks recorded in CR39 exposed simultaneously under similar conditions.
