A Low-Energy X-Ray Irradiator for Electrophysiological Studies

Abstract

A 50 kVp molybdenum target/filter x-ray was installed inside a lead- shielded Faraday cage. High-dose rates of up to 1.54 Gy/min (17.4 keV weighted average photons) were used to conduct local in vitro irradiations of the hippocampal region of guinea pig brains. Electrophysiological recordings of subtle changes in neuronal activity indicate the system is suitable for this application.
