<p><P>PROBLEM TO BE SOLVED: To provide a radiation environmental information providing device for reducing radiation exposure autonomously by easily conveying radiation environmental information for each area in a controlled area to a person engaged in radiation business who enters the controlled area. <P>SOLUTION: A radiation measuring means 11 for measuring surface dose rate per pipe for each system in a nuclear power plant, or for performingγ-scan measurement is provided. An operation processing means 13 obtains radiation source intensity magnification for each system, based on a measurement value obtained by the radiation measuring means 11, and multiplies a dose rate matrix created in advance by the radiation source intensity magnification to create the spatial distribution diagram. Then, the spatial distribution diagram of the dose rate is updated and outputted by an information outputting means 14, and radiation environment information changing in real time from smaller number of measurement points is provided to the person engaged in radiation business. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
