The structure changes of Peganum harmala connected by the γ-irradiation influence have been studied by means radiothermoluminescence (RTL) and IR-spectroscopy methods. It is established that at a small dose 0.5<Dγ≤25 kGr region the structure changes of alkaloids d’ not takes place, but at dose 25<Dγ≤50 kGr region – particular decay. The possibility to applied a small dose region for radiation sterili- zation of Peganum harmala have been shown. The dose bounders of the radiation sterilization have been de- termined.
