20090070070 | ENVIRONMENTAL RADIOACTIVITY MEASUREMENT SYSTEM OF ADMINISTRATION AND AN ANALYSIS METHOD OF THE RADIOACTIVITY - 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 accurate 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. There are provided an environmental-radioactivity measurement/management system which allows measurement specimens for measuring the environmental radioactivity to be processed at low cost and in large amounts, and the analysis method for the radioactivity intensity. | 03-12-2009 |
