Conceptual design of thyroid dose monitoring system using $$gamma$$-ray spectrometers

no journal, , 

In the situation of a severe nuclear accident, radioiodine monitoring in thyroid should be performed for a large number of people immediately after accident. We propose conceptual design of the portable thyroid dose monitoring system consisting of two $$gamma$$-ray spectrometers and radiation shield, which is easily used at evacuation centers and incident command posts in the radiologically affected area. The experimental study of detectors and radiation shield were performed to confirm if the proposed monitor can satisfy the performance requirements. As a result, it was confirmed that the proposed monitor can assess thyroid equivalent dose less than 10 mSv by adopting CdZnTe or LaBr$$_{3}$$ detectors with a tungsten heavy alloy shield, even in a high dose rate condition around several 10 $$mu$$Svh$$^{-1}$$.

There has been a growing demand for knowing time series changes in air dose rate and concentration of radioactive materials. Also, from the beginning of the accident, there were a lot of requests for local monitoring information specialized in the area where individuals live or want to know. To respond to those requests, we had improved and developed the information systems using software platform for environmental monitoring data which developed already. Several visualization information that made time series changes easier to understand were added to the Environmental Monitoring Database. Also, we had developed the Environmental Monitoring Infographics which statistically analyzes a large amount of environmental monitoring data and visualizes the change of air dose rate and concentration of radioactive materials. Moreover, we developed the Mapping Tool that can map and graph local environmental monitoring information.
