1. Kagawa National College of Technology ShogoYamashita, Ayako Yano, Chisato Mouri, Hideki Tenzou, An AR Radiation Field Visualization System for Monitoring Neutron Activation Sources 1st International Symposium on Technology for Sustainability 23-26 November 2011,KMITL, Bangkok Thailand. 20 2st International Symposium on Technology for Sustainability 21-23 November 2012,KMITL, Bangkok Thailand

2. Radiation Survey The operator must be know where to test for radiation. Conventional radiation detectors are not efficient for measuring radiation distribution intensity of current position only Radioactive source

3. Purpose To develop a radiation field visualization system that can display distribution. How to visualize A radioactive source Graphics are composted with live images from a USB camera. Generated graphics represent radiation distribution

4. System Configuration USB Camera 3D Graphics PC Radiation Detector Radioactive Source AR-Tags This system uses a radiation detector for measuring radiation intensity

5. System Configuration USB Camera 3D Graphics PC Radioactive Source AR-Tags Radiation Detector A USB Camera is used to capture images which will be used to generate spatial calculations and image composting

6. System Configuration USB Camera 3D Graphics PC Radioactive Source AR-Tags Radiation Detector USB Camera Two AR Tags are used as reference points for the spatial calculations.

7. System Configuration USB Camera 3D Graphics PC & Display Radioactive Source AR-Tags Radiation Detector USB Camera

8. About radiation Radiation is similar to fireworks Radiation is similar to fire spark of fireworks Fireworks hold in Japan Cloud Chamber which can visible radiation Radioactive source White cloud line represents radiation from the radioactive source

9. About radiation Radiation is similar to fireworks Radiation intensity is number of radiation per time counts the number of radiation as radiation intensity Radiation detector Radiation intensity is similar to number of fire spark

10. About radiation Radiation is similar to fireworks Radioactive source Shielding material (Pb) Which does not let radiation pass Radiation intensity distribution is depend on the experiment environment Low radiation intensity High radiation intensity

11. Movie of measurement Radiation intensity is color coded. CPS: Count Per Second A radioactive source Each tags position and orientation are acquired by the system To get the current measured points

12. Views from Optional angles The graphics can be seen from an optional angle frontTopSide

13. Receiving data from detector This construction makes the system adaptable to other types of conventional detectors and additional detectors. Visualization system Measuring system A serial connection Stack the radiation intensity data and the measured position data send the intensity date Each systems are independent each other These are connected by a serial connection

14. In the future Making a table which has a lot of radiation detectors To visualization distribution in real time without scanning. Radiation detector Around 50 ($) Visualization System Arduino

15. Conclusion In the future of this system A radiation field visualization system was developed to monitor radiation distribution This system will be able to accommodate large number of detectors Measuring the distribution in real time without scanning Radiation distribution is visible in this system The graphics are configurable from within the GUI. A simple serial communication method is used to make the system adaptable
