A Web-Based Private Permissioned Blockchain for Ionizing Radiation Management: A Case Study of The Tanzania Atomic Energy Commission
Abstract
The intricate software and hardware configurations of nuclear regulatory systems, such as
ionization radiation inspection systems, and maintaining and monitoring their integrity pose
challenges. Traditional methods of managing ionization radiation data often lead to
vulnerabilities such as data manipulation and inefficiency in handling information, which can
result in compromised safety measures and regulatory non-compliance. Recording electronic
ionization radiation and related data in spreadsheets or other obsolete systems poses a threat to
information security due to accidents. This project addresses the challenges of managing
ionization radiation data within nuclear regulatory systems by developing a private
permissioned blockchain Management Information System for the Tanzania Atomic Energy
Commission (TAEC). The primary objective is to enhance data security, operational efficiency,
and regulatory compliance through a secure, immutable, and transparent digital platform. The
project employed qualitative data collection methods, including user stories from focus groups
with TAEC staff. The system leveraged smart contras (chaincode) to automate processes and
enforce rules. It was developed using Hyperledger Fabric and followed the Extreme
Programming (XP) methodology. A prototype was implemented to demonstrate the feasibility
of this approach, focusing on the general inspection process of ionization radiation sources and
facilities. The system successfully automated inspection scheduling, data recording, and report
generation reducing processing time from days to hours while improving data integrity,
transparency and accessibility. Validation results indicated high user satisfaction, with 94%
agreeing on the system's usability and data security. The blockchain framework ensured secure
and tamper-proof record-keeping, meeting regulatory standards and enhancing ionization
radiation operational workflows at TAEC.
