TASTRAK Applications and Basic Data

TASTRAK, a form of CR-39, is a clear, stable plastic which is sensitive to the tracks of energetic protons, alpha-particles and heavier nuclei. After exposure, the tracks may be revealed by etching the material in solutions such as caustic alkalis. TASTRAK is used for radon detection (more than one million radon measurements have been made with the material), neutron dosimetry, fusion studies, alpha-particle autoradiography and low-level counting, uranium exploration, cosmic ray studies and the teaching of radioactivity in schools and colleges. The Human Radiation Effects Group in the Physics Department at Bristol University uses TASTRAK for analysing natural alpha- radioactivity in the human body and for a wide range of studies of natural alpha- emitters in the environment.
