摘要： At a worksite of a client, progeny nuclides of radon and thoron are collected into a filter, then making the gross measurement on α-ray amount within an hour from the collection. Next, the filter is sent to an analysis center with information added thereto, such as collection-condition information, gross-measurement information, and sampling-worksite information. At the analysis center, the gross measurement on the filter sent thereto is made again. Also, the radioactive-nuclide analysis is made to perform evaluation of the radioactivity intensity. Moreover, radon amount and thoron amount at the measurement-specimen sampling points-in-time at the worksite are calculated, then reporting the analysis result of the radon and thoron amounts to the client.

摘要： An α-ray measuring apparatus is provided for accurately analyzing the energy of a trace of α-rays emitted from a sample in a short time using semiconductor detectors which excel in energy resolution. The α-ray measuring apparatus comprises an α-ray detector including a plurality of semiconductor detectors, an adder for adding output signals from the respective semiconductor detectors, an anticoincidence counter for anticoincidently counting the output signals from the respective semiconductor detectors, and a peak analyzer for analyzing an energy distribution of the α-rays based on an addition of the output signals from the semiconductor detectors which are not anticoincidently counted. Since the output signals from the plurality of semiconductor detectors are added to increase the area of a sample under measurement and also remove background noise, the α-ray measuring apparatus can more accurately analyze the energy of the α-rays while reducing a measuring time.

摘要： A neutron individual dose meter and a neutron dose rate meter, both capable of implementing the effective dose equivalent response. The neutron individual dose meter is capable of being accomplished by providing a composite layer made up of a converter such as boron, and a proton radiator, on the surface of a semiconductor neutron detection element. The neutron dose rate meter is capable of being accomplished through such a structure as to surround a neutron detector with a neutron moderator and a thermal neutron absorber which has openings. Thus, a neutron individual dose meter and a neutron dose rate meter, both capable of implementing the effective dose equivalent response and measurement at lower operating voltage have been provided. Further, these meters are capable of being implemented by utilizing a single semiconductor detection element, respectively.
