Radiation stability of lindane and active substance of hexachlorane dust preparation under electron irradiation

Electron beam impact on the radiation resistance of organochlorine hydrocarbon is considered for two forms of pesticide – a pure chemical compound and a component of active substance of a pesticide product to be disposed of. State standard reference samples (SRS) of hexachlorocyclohexane (HCH) – lindane and hexachlorane dust – are used. The fullness of decomposition are determined for lindane and organochlorine compounds as part of the active substance, depending on the aggregate state of the preparation and the absorbed dose of electronic radiation. In all samples, a reduction in the radiation resistance of HCH and its isomers is detected within the range of the radiation dose (D) from 10 to 200 kGy. The maximum decomposition is observed in the suspension of the preparation. The dependence of a degree of decomposition on the amount of radiation dose is not linear. (paper)
