Abstract

Zooplankton contained in water have been successfully inactivated by irradiation with a pulsed intense relativistic electron beam (PIREB). A treatment chamber is filled with a solution of 3-wt% salt in water containing Artemia larvae as zooplankton samples and is irradiated using the PIREB (2 MeV, 0.4 kA, 140 ns). We found that up to 24% of the Artemia are inactivated by firing 10 shots of PIREB irradiation.
