Searching for Strangelets (small pieces of strongly interacting matter comprising of nearly equal numbers of u, d and s quarks) in cosmic rays, an experiment has been done at Antarctica using passive detectors. We have exposed CR-39 and PET (polyethylene terephthalate sheets) at Maitri and Bharati experimental stations of India. High detection threshold detector PET limits the detection of cosmic rays to relatively high Z and low energy particles. In this report we will present charge response parameters (Vt /Vb ) for charged cosmic ray particles observed at ground level. Track parameters viz. diameters, depths and incidence angles of observed charged particles in CR-39 show wide distributions. Identification of different groups of particles has been done from the distribution of charge response parameters (V t /V b ) with the help of the calibration curve of CR-39. Flux of charged particles observed in CR-39 is ~6.2x10 -4 /(cm2.sec.sr) at both the places.
