摘要：

Photon and electron irradiation effects in cables and connectors of ionization chambers were investigated under different experimental conditions by means of measurements of the chamber response to a Sr-90 standard check source and by measurements of radiation-induced leakage current. Correction factors for irradiation effects on cables and connectors were obtained as a function of the radiation energy, cable length, and absorbed dose dependences.
