We developed a high precision ionization chamber MALIC. It is an integral type ionization chamber which has a magnetically levitated electrode without being supported by insulation materials. Furthermore, the electric potential of that electrode can be read without physical contact, so that the contact noise does not occur. With MALIC, we attempted to measure the radiation dose from tritium vapor of a room air in an accelerator facility.
