Sealed Source meaning
Published by a LexisNexis Energy expert
What does Sealed Source mean?
In legal practice, a sealed source is a quantity of radioactive material fixed within a robust capsule or solid matrix so the radionuclide cannot readily disperse, greatly reducing contamination risk. It is used in medicine (notably brachytherapy and calibration), industry (industrial radiography, level/density gauges and oil and gas well logging), research and education.
The term is defined in legislation, including the Ionising Radiations Regulations 2017 (Great Britain) and Ireland’s Basic Safety Standards regulations, generally as radioactive material permanently sealed in a capsule or closely bonded in solid form; it typically excludes sources inside a nuclear reactor and material encapsulated solely for disposal.
Key legal features include: authorisation or permit to keep and use the source; employer duties for risk assessment, maintenance and periodic leak testing; security and accountancy of sources; safe transport under the Carriage of Dangerous Goods regime; and end-of-life management or return to the supplier. High-activity sealed sources (HASS) are subject to additional controls on security, tracking and financial provision.
Usage and regulatory approach are broadly consistent across England and Wales, Scotland, Northern Ireland and Ireland, though the permitting framework differs (for example, Environmental Permitting in England and Wales, EASR in Scotland, Northern Ireland equivalents, and EPA licensing in Ireland).

UK private-sector outsourcing procurement: selecting providers via sole source, competitive and sealed bids, RFx and BAFO/BARFO guidance for commercial lawyers
Originally authored by James E. Meadows, Culhane Meadows PLLC for Lexis Practical Guidance® US, and adapted for Lexis+® UK. This Practice Note sets out the issues a customer commissioning an outsourcing should consider in engaging with the market of potential service providers, together with alternative ways to progressively narrow options at key points in the selection journey. It is intended for general commercial practitioners advising private sector business customers on outsourcing transactions, and it does not address public procurement outsourcing. In choosing a procurement route for an outsourcing agreement, there is no single strategy that suits every case; distinctive circumstances often demand a bespoke approach. For example, although clients (customers of outsourcing services) frequently favour competitive tendering, in particular situations a sole-source option can secure terms comparable to those typically achieved through formal competition, particularly where existing relationships can be leveraged or a phased path is adopted to realise the outsourcing function’s aims. The most appropriate solution often involves nuanced variations on conventional wisdom...

UK legal framework for transport of nuclear materials: Brexit changes, international standards, security, packaging, liability, and transboundary waste and sealed source shipments
What is the impact of Brexit on the UK nuclear sector? From 31 January 2020 (the exit day), the UK stopped being an EU Member State. Yet, at that moment it moved into a transition/implementation phase, during which, for many purposes, the EU continued to treat the UK as if it were still a Member State. Leaving the EU also entailed leaving the Euratom Community. At 11 pm (GMT) on 31 December 2020, the transition/implementation phase concluded. In UK law this point—‘IP completion day’—ended core transitional measures and ushered in notable changes across the UK’s legal framework. The UK’s departure from the EU likewise resulted in departure from Euratom. Any amendments pertinent to this material will be detailed below. After IP completion day, the European Union (Withdrawal) Act 2018 (EU(W)A 2018) established a new class of domestic legislation—‘retained EU law’ (REUL)—consisting of preserved EU-derived rights and instruments following Brexit. On 29 June 2023, the Retained EU Law (Revocation and Reform) Act 2023 (REUL(RR)A 2023) received Royal Assent. REUL(RR)A 2023...
