Abstract
In projecting radioactive rays for sanitizing food or the like, an irradiating condition which attains a uniform dose of radioactive rays for the entire objects to be exposed is automatically determined. An X-ray CT unit captures a sectional image of an object to be exposed , and an irradiating condition determining section acquires the density distribution of the object to be exposed based on the captured sectional image. The irradiating condition determining section then searches for a particular irradiating condition under which the dose distribution of the radioactive rays in the object to be exposed falls within a predetermined range. An irradiation controlling section controls a radioactive ray irradiating unit based on the irradiating condition, and projects radioactive rays to the object to be exposed in accordance with the irradiation condition when the object is transported to the radioactive ray irradiating unit by a belt conveyor.
