This invention enables highly accurate sample analysis by analyzing energy spectra obtained using a radiation detector, even under a high dose-rate environment.

Next, a corrected spectrum is calculated as the difference between the measured spectrum and the background nuclide-originating component (corrected spectrum calculation step: S4).

On the other hand, a three-dimensional space from which such a region as no radiation source exists is removed is specified using the projection image of a Compton cone obtained from the detection data outputted from each camera head and projected onto a two-dimensional plane and an image based on the radiation source is reconfigured in the three-dimensional space thus specified.
Provided is a method for quickly separating radioactive copper from nickel containing radioactive copper and radioactive cobalt. The nickel that contains radioactive copper and radioactive cobalt is dissolved in an acidic solution and passed through a chelate exchange resin-filled column to retain the nickel, the radioactive copper, and the radioactive cobalt in the chelate exchange resin. Then the radioactive copper and the radioactive cobalt are eluted by passing an acidic solution through the chelate exchange resin-filled column. Then an acidic solution that is more highly concentrated than the previous acidic solution is passed through the chelate exchange resin-filled column after the nickel and radioactive cobalt elution in order to elute the radioactive copper.

There is a technique in which an ultrasonic wave is propagated to an aqueous solution of tetravalent platinum ions containing a small amount of 2-propanol to thereby reduce the tetravalent platinum ions to platinum metal. However, the mere addition of 2-propanol as in that technique cannot produce a reducing ability sufficient for the reduction of hexavalent uranium to tetravalent uranium with ultrasonic propagation. A solid noble-metal catalyst is used to enhance the reducing ability brought by ultrasonic propagation and thereby attain the reduction of hexavalent uranium in an aqueous solution to tetravalent uranium.

METHOD OF DECONTAMINATING RADIOISOTOPE-CONTAMINATED SURFACE VICINITY REGION BY USE OF NONTHERMAL LASER PEELING WITHOUT RE-MELTING, WITHOUT RE-DIFFUSION AND WITHOUT RE-CONTAMINATION, AND APPARATUS THEREFOR
With respect to the method of removing a surface-adhering coating contaminated with radioisotope, as the applicability conditions, such as object, place and configuration, are strict, the scope of application thereof is quite limited. Thus, 100% decontamination cannot be attained, and while half or more can be decontaminated, substantial portion of the adhering radioisotope remains, that is, the decontamination capacity effect is very limited. There is provided a method of decontamination by the use of nonthermal laser peeling without re-melting, without re-diffusion and without re-contamination, in which parts, structures, etc. with surface contaminated with radioisotope of an accelerator, atomic reactor, radioisotope production plant, nuclear fuel plant, nuclear fuel reprocessing plant, etc. are exposed to nonthermal laser irradiation so that laser-irradiated surface vicinity regions are evaporated off faster than the transfer of heat generated in the vicinity of irradiated surface to its periphery.

In order to increase the diffraction efficiency by forming a multi-layer film on a laminar type diffraction grating surface, it is necessary to satisfy four conditions: [1] condition of a groove depth capable of obtaining the optimal reflectivity; [2] extension Bragg condition of the multi-layer film; [3] condition expression defining correlation between directions of an incident light and a diffracted light; and [4] a ratio of the width of convex portion against the concave portion on the laminar type diffraction grating surface. However, there has been no unified design guideline. The present invention solves this problem by giving a general design guideline and an optimal multi-layer substance pair so as to provide a diffraction grating having both of a high diffraction efficiency and a high resolution in the wavelength region of 0.1 to 1 nm where spectroscopy using a diffraction grating is difficult because of the efficiency lowering.

A technique by which a high-frequency substrate having excellent conductor adhesion can be obtained. The high-frequency substrate comprises a base material and a conductor adherent thereto, the base material comprising a polymer obtained by graft-polymerizing up to 1 wt.% monomer having an affinity for the conductor with a fluoropolymer. A film of a fluoropolymer is irradiated with electron beams or otherwise treated to form active sites reactive in graft polymerization. Thereafter, this fluoropolymer film is introduced into a solution of a monomer having an affinity for the conductor to conduct graft polymerization. The conductor is adhered to the graft polymer to produce the substrate. In the graft polymerization step, the degree of grafting of the monomer is regulated to 1 wt.% or lower based on the fluoropolymer.
