A literature review on the regulation of radiation systems in Sierra Leone.
A Literature Review: The Regulatory Legal Framework on Radiation Systems in Sierra Leone
1. Introduction: The Imperative for a National Regulatory Framework
The peaceful application of nuclear and radiation technology is a cornerstone of global development, with applications spanning medicine, industry, agriculture, and research. However, the inherent risks associated with ionizing radiation—potential harm to human health, safety, and the environment—necessitate a robust and comprehensive legal and institutional framework for its control. Globally, the International Atomic Energy Agency (IAEA) serves as the primary body for setting a foundational standard for nuclear and radiation safety. These standards, however, are not legally binding on member states; instead, they serve as a blueprint that individual nations must translate into enforceable domestic law and policy at their discretion. This literature review provides a critical analysis of Sierra Leone's efforts to establish such a framework, specifically examining the Nuclear Safety and Radiation Protection Act, 2012, its subsequent 2022 amendment, and the broader regulatory ecosystem. The review synthesizes legislative documents, international reports, and scholarly articles to identify the framework's strengths, persistent gaps, and implementation challenges. The analysis is framed within a comparative context, benchmarking Sierra Leone against its West African peers, Ghana and Nigeria, to identify lessons and provide a conceptual model for future development.
2. The International Architecture: Principles and Conventions
The global regulatory system is a multi-layered structure built on non-binding standards and legally binding conventions. The IAEA’s principal objective is to promote the peaceful uses of atomic energy while ensuring the "minimization of danger to life and property". It achieves this through its Safety Standards Series, which covers nuclear, radiation, transport, and waste safety and is categorized into Safety Fundamentals, Safety Requirements, and Safety Guides. Beyond these non-binding standards, a series of international conventions impose specific legal obligations on signatory states. Key instruments include:
- The Convention on Nuclear Safety (CNS): A legally binding treaty for countries operating civilian nuclear power plants that commits them to maintaining a high level of safety through international benchmarks.3
- The Convention on Early Notification of a Nuclear Accident: This convention establishes a system for immediate reporting to the IAEA and affected states in the event of an accident with potential for transboundary radiological release.3
The Convention on the Physical Protection of Nuclear Material
(CPPNM): This is the only legally binding international agreement mandating physical protection standards for civil nuclear materials, especially during transport.3It also requires states to criminalize the malicious misuse of nuclear material.3 The Joint Convention on the Safety of Spent Fuel Management and on the
Safety of Radioactive Waste Management: This instrument obligates contracting parties to establish a comprehensive legislative and regulatory framework for the safe management of spent fuel and radioactive waste.3 A significant finding in the research material is that as of May 2022, Sierra Leone's status on making a "Code of Conduct Notification" to the IAEA is "Unknown". This non-legally-binding code on the safety and security of radioactive sources is a key indicator of a state's political commitment to and engagement with the international framework. This "Unknown" status suggests a potential gap in the country's formal participation in the global safety regime, which may hinder its ability to secure necessary international technical cooperation.
3. The Sierra Leone Regulatory Framework: Evolution and Provisions
Sierra Leone's legal framework for radiation safety is anchored in the Nuclear Safety and Radiation Protection Act, 2012, which repealed the previous 2001 act. The primary purpose of the 2012 Act was to establish a dedicated institutional body—the Nuclear Safety and Radiation Protection Authority—to "exercise regulatory and supervisory control for the beneficial and peaceful uses of radioactive substances". The Act initially applied to "every source of ionising radiation". To operationalize this new law, the government enacted the Nuclear Safety and Radiation Protection (Fees and Charges) Regulations, 2013. These regulations detailed a comprehensive fee schedule for various activities, including licensing, inspections, and even the analysis of foodstuffs for radioactivity, and defined dangerous radioactive materials into three categories based on their potential to cause harm. Recognizing the need to update its legislation and align it more closely with international best practices, Sierra Leone passed the Nuclear Safety and Radiation Protection (Amendment) Act, 2022. This amendment introduced several critical changes:
- Expanded Scope: The most significant change was the replacement of the term "ionizing radiation" with the broader "radiation" throughout the Act, expanding the Authority's mandate to include "non-ionizing radiation" sources like ultraviolet radiation, magnetic resonance imaging, and lasers.10
- Ministerial and Board Reforms: The Minister's portfolio was changed from Energy to the "Minister responsible for the Environment," signaling a conceptual shift in governance.10The composition of the Authority's Board was also reformed to include a wide array of representatives from key ministries and agencies, including the Ministries of Finance, Health, and Information, as well as the Sierra Leone Police and the Office of National Security.10
- New Regulatory Powers: The Authority's functions were expanded to include new mandates, such as monitoring all base stations and masts for compliance and monitoring foodstuffs for radioactive contamination.10
- Revised Classifications and Penalties: The amendment introduced a more detailed classification system for radioactive substances (five categories) and nuclear materials (three categories).10Penalties for offenses such as willfully withholding information were revised to a fine of not less than 10,000,000.00 Leones or imprisonment for up to two years.9
4. Identified Regulatory Gaps and Implementation Challenges Despite these commendable legislative updates, a critical review reveals foundational deficiencies in the framework. These gaps are not merely technical but are often symptomatic of broader governance challenges in the country, such as "weak policies and institutions," "corruption," and a lack of "inter-sectorial coordination". The research material explicitly identifies the following key deficiencies:
- Lack of Independence: The framework does not assign regulatory responsibilities to a legally independent body, nor does it prohibit conflicts of interest among regulatory staff.5The absence of an impartial body undermines public and effective oversight.
- Absence of Key Regulatory Tools: The State lacks a legally referenced "list of controlled sources".5This is a profound regulatory flaw, as it undermines the ability to implement a graded approach to security based on the potential danger of a source. Furthermore, the framework lacks a legal requirement for a national threat assessment related to radiological materials, and there is no mandate for law enforcement to participate in such assessments.5
- Deficiencies in Disused Source Management: The framework fails to impose clear responsibilities for the management of "disused sources".5There are no requirements to identify who is responsible for the costs of managing these sources, to notify authorities when a source becomes disused, or to establish provisions for secure short-term and long-term storage facilities.5The absence of a strategy for regaining control of "orphan sources" also represents a major security vulnerability.5
- Enforcement Weaknesses: Penalties for violations are not linked to the different categories of sources, and there is no provision for a warning for minor violations, which could prompt corrective action before a more severe measure is necessary.5 These regulatory gaps are compounded by broader human capacity challenges. A study on radiation safety awareness among medical staff in Bo Government Hospital found "considerable variation" in understanding of specific protective measures and regulations, highlighting the need for comprehensive training and education to foster a stronger safety culture.
5. Comparative Analysis: Benchmarking against West African Peers A comparison of Sierra Leone's framework with those of Ghana and Nigeria provides valuable context and actionable insights. The resources and regulatory progress of Ghana and Nigeria "far outweigh what exists in the other West African countries".
- Ghana: The Ghanaian Nuclear Regulatory Authority (NRA), which became operational in 2016, regulates both ionizing and non-ionizing radiation and has a clear vision to protect humans and the environment.15The NRA's institutional structure is mature, with a Director General, a Deputy Director General, and three directorates with fifteen departments to carry out its mandate.15
- Nigeria: The Nigerian Nuclear Regulatory Authority (NNRA), established by the Nuclear Safety and Radiation Protection Act, 1995, is a highly structured body.17Its Radiological Safety Department is divided into five distinct divisions: Industrial Application Safety, Waste Safety, Public Exposure and Environmental Safety, Transport Safety, and Mining & Radiation Protection Services.17This specialized structure allows for targeted and detailed oversight of specific practices, such as maintaining a national radioactive waste registry through its dedicated Waste Safety Division.17 This comparative analysis demonstrates that while Sierra Leone has made commendable legislative progress, its institutional and operational frameworks have yet to reach the maturity of its regional peers. The specialized structures of the Nigerian and Ghanaian authorities, with dedicated divisions for functions like waste management and transport, serve as a clear blueprint for what Sierra Leone's Authority could develop to effectively address its identified deficiencies.
6. Conclusion and Future Research Directions
The analysis reveals a complex and evolving regulatory landscape in Sierra Leone. The 2022 Amendment Act is a significant legislative step forward, signaling a genuine commitment to modernizing the law, broadening its scope, and legally mandating inter-ministerial collaboration. However, the framework continues to suffer from foundational regulatory deficiencies, most notably the lack of an independent regulatory body, the absence of a legally referenced list of controlled sources, and a failure to establish a clear and enforceable strategy for the management of disused sources. These challenges are linked to and exacerbated by broader governance issues and human capacity constraints within the country.
Future research should focus on the practical implementation of the 2022 amendments. This could include qualitative studies to assess the effectiveness of the new multi-ministerial board in practice, or empirical studies to quantify the operational and resource constraints hindering the Authority's enforcement capacity. Furthermore, a comparative case study analyzing the operational structures of waste management in Nigeria and Ghana could provide actionable, context-specific recommendations for Sierra Leone to address its disused source management gap.
