Abstract

PURPOSE:To enhance the current amplification effect by placing substances differing in work functions and ionizing the gas existing in the space sealed with radioactive substance to generate current and voltage and by composing electrodes with thin filaments. CONSTITUTION:Thin, bar-form electrodes 2, 3 are alternately placed on a borosilicate glass plate 1, and a glass cover 5 is put thereon to cover them hermetically. In this enclosed space 4 is sealed radioisotope gas 4. By thus constituting, in the electric field generated in the substances 2, 3 differing in work functions, + and - ions are gathered in each electrode while amplifying the current. This amplification effect is larger as the electrodes 2, 3 are smaller in thickness. When the inside of the upper face of cover glass is coated with fluorescent material 6 fluorescent material emit fluorescence by the radioactivity of the sealed gas 4 and it may be used as lighting in darkness.
