The development of a novel technique to evaluate the CR-39 track response to alpha particles

Abstract

A novel technique is presented for the assessment of the track response of the detector CR-39 to alpha particles by photothermal de ection spectroscopy and image analysis. The 2 new techniques can be implemented to CR-39 as in situ measurements. The proposed techniques offer the possibility of monitoring nuclear radiation directly. Photothermal de ection is described to detect the change in the thermal and optical properties of the track nuclear detector CR-39 when irradiated to alpha particles. In situ image analysis of the photothermal de ection spot is presented to assess the detection of the CR-39 of any nuclear particle or radiation instantaneously. © TÜBITAK.
