PROBLEM TO BE SOLVED: To prevent a rise in a preserving temperature of blood when blood packs are left as they are by constituting a cold insulation device provided in a blood pack taking-out port of an X-ray irradiator to irradiate X-rays to the blood packs by having an electronic heat exchange element such as a Peltier element and a cooling means using compression/evaporation of refrigerant gas. SOLUTION: An X-ray irradiator of blood packs successively automatically irradiates X-rays to the blood packs when plural blood packs are set inside so that the blood packs after irradiation are discharged to a taking-out port. In this case, a cold insulation device C is integrally arranged in the taking-out port to prevent a temperature rise in blood when forgetting to take out the blood packs from the opening part. This cold insulation device C is constituted by installing heat exchangers 6 by cutting off a part of a heat insulating material 4. The respective heat exchangers 6 are constituted of an electronic heat exchange element such as a Peltier element and a cooling means using compression and evaporation of refrigerant gas to thereby cool the blood packs.
