This paper describes the synthesis and development of new polymers for solid state nuclear trak detector of two novel poly Allyl cloride – co Acrylic acid and diethanol amine of polymeric detectors of alpha charged particle tracks. The detectors were irradiated by two radioactive sources, Amercium (Am-240) and Polonium (Po-210) for 5 hours, and traces of alpha particles were seen in the microscope and their diameters were measured. The results showed the density of tracks of alpha particles from (Am-240) and (Po-210) are 295.86, 655.33 respectively, while the average of their diameters are 5.83, 4.78 respectively.
