Abstract

PURPOSE:To improve dielectric-strength, by exercising discharge processes of highvoltage and low-voltage electrodes after activating an electron-radioactive substance and by removing harmful matter easy to emit electrons vapor-deposited on both the electrodes during the activation of the radioactive substance.
