The radioactive methyl iodide method is one of the important ways to test iodine adsorbers. The methyl iodide generator is the key equipment in this method. In this paper, the structure, technical specifications and results of performance tests of a self made generator are introduced. The generator is comprised of methyl iodide generator body, pneumatic control sysytem and negative pressure box with accesories. The results of 'hot test' showed that all operating parameters could be controlled within normal range, the generating flow rate was stable, and the generating rate and purity of the methyl iodide could meet the requirements of iodine adsorber test. In addition, safety protection system and off gas clean system were designed in the generator to effectively avoid radioactive gas escaping outside. The generator is portable with small size and light weight, which is convenient for on site use. (
