摘要： PROBLEM TO BE SOLVED: To provide an inexpensive device for practical use for making waste harmless by irradiating the waste with radiation to decompose harmful chlorine- containing organic materials contained in the waste. SOLUTION: A cylindrical inner container 2 for housing the waste to be treated is installed almost in the center inside a steel-made outer container 1 consisting of a cylindrical container body 1A, a bottom 1B and a cover 1C. Plural cylindrical radiation source housing containers 3 capable of housing respective gamma ray sources are attachably/detachably disposed to surround the inner container. The radiation source to be used is selected from a spent control rod used in a nuclear reactor, a channel box and a high level radioactive waste glass-solidified body. The container 1 has a thickness enough to prevent harmful level radiation from emitting to the outside when the radiation source is housed. The containers 2 and 3 are made from a material and have the thickness which allow the transmission of a gamma rays.

摘要： PROBLEM TO BE SOLVED: To fill a metal into a through-hole in a ceramic board through an economical process, without the need for complicated operations and to realize high density and high performance of a board circuit. SOLUTION: A ceramic board 10 in which a through-hole is formed and a metal plate to which an activation treatment is not executed are pasted by a screw or the like to form a laminated object. The laminated object is immersed in an electroplating liquid. Electroplating treatment is executed on the metal plate, which is exposed in the bottom part of the through-hole. The metal is precipitated on the inside of the through-hole so as to be filled into the inside of the through-hole. At this time, by having a filling metal 11 grow by the thickness portion of the ceramic board 10, the ceramic board is polished, and a metal-filled ceramic board which is flat is obtained. In addition, by having the filling metal 11 grow so as to form a gap part 12 inside the through-hole, e.g. a semiconductor element can be embedded in the gap part 12, and planarization of a circuit can be made.
