Abstract: The present invention relates to a composition for preventing odors containing odorless microorganisms or a culture thereof. The present invention also relates to a method for preventing odors including coating the composition for preventing odors. When a biofilm is formed by coating an object offensive odor-generating microorganisms can inhabit with the composition for preventing odors of the present invention, odors can be effectively prevented by significantly preventing the inflow and inhabitation of outside microorganisms that may generate offensive odors.

Abstract: A radiation shield to locally apply radiation includes a source irradiating the radiation, and a shielding member is formed so that the radiation is incident only to a localized area of an object or a body to be inspected or treated and the other parts are shielded. According to the present invention, since the radiation is applied only to a part to be radiographed or treated, it is possible to provide the radiation shield which may locally irradiate the radiation to an object or a body to be inspected or treated. Furthermore, according to the present invention, it is possible to provide the radiation shield which may be used along with a radiation irradiation apparatus (60Co Therapy, CyberKnife: a collimated source) universally used in existing medical institutions and also may accommodate a separate radioactive source (an uncollimated source) to be used.
