Monitoring and Advising System for Iodine Status

Abstract

<p> Iodine-125 is produced from Xe-124 at McMaster Nuclear Reactor (MNR) for medical applications. Excessive amounts of this isotope in the air of the reactor site can be hazardous especially for the staff members who are continuously working at the reactor building. Therefore there is a critical need to monitor the concentration of iodine released to the air. In the previous iodine monitoring system available at MNR, there were several technical and practical problems. Consequently a new monitoring system was designed to overcome the previous problems and to provide with further facilities for the staff. The system is developed in the LabVIEW1 platform and is easily maintainable. The external data acquisition board LabJack is used to transfer the data to the PC. Briefly, by using radiation monitoring techniques and statistical methods, a computerized embedded system is designed to keep the MNR a safe place for operators and visitors. This thesis examines in detail the design and implementation of the new monitoring system, MASIS.</p>
