Lifetime of positronium in anti-oxidants and carcinogens

The method of positron annihilation lifetime spectroscopy in the study of the lifetime of positronium in the substance is carcinogenic and anti-oxidants. This method is based on the nature of the electrophilic carcinogens and a complete contrast—antioxidants, and the sensitivity of the method PAVS—change in the lifetime of positronium, depending on the electron density of the environment.We discuss the differences annihilation temporal characteristics of some carcinogens and antioxidants.
